When mentioning the oil thinning out in high heat conditions it reminds me of what I read on the Redline bottle that states that it actually has a higher viscosity than 90w dino oil at 300 degrees and less viscosity at lower temps.
Sure feels like it to me. I ran to Canada and back last weekend, it was HOT and it shifted great!

On hot days, does anyone notice that the shifter gets stiffer?
It's kinda hot today (96) and driving in traffic the shifter got harder then usual. Not difficult, just harder. Also coming into the garage, I have a 25 degree upslope to get in and once on a flat surface, the shifter got loose like it was disconnected. two seconds later it was stiff again.
I am assuming that the oil thined WAY OUT due to the heat raising the pressure in the transmission (i have a breather line) and the up slope caused the fluid to (un)cover the linkage allowing the disconnected symptom? It's fine now after it cooled down.
These things (ferrari's)make PMS look like a cakewalk. |

Bob, try shifting 1-2 when cold...barely perceptible stiffness for me...just about perfect, and never was that good with the previous stuff (unknown) or the Mobil 1 I put in. |

I just replaced the Mobil 1 with Redline 75W90NS per Redline's recommendation (I was replacing the TO bearing, so...). The rear end chatter at tight stop sign corners is gone, and it was really there before (annoying). I can't tell if it shifts any better, still feels like it always did. |

According to Ferrari UK they use/recommend SHELL DONAX 75W 90. I checked the Shell site and this is listed as a transmission oil ?? I would have expected the SHELL SPIRAX S to be recommended looking at their website info. Anyone using Shell for a 308/328 ? |

Guys,
I am having all bronze gears made and using straight dexcool in the gearbox this should solve the gearbox problem.
Just kidding.......
I still suggest AGIP "the right stuff"!!!

Joe,
This is why Redline says to use the 75w-90 NS, and then add the limited slip additive only if necessary, and only the amount needed, and no more. |

Here is a link for P cars that seems applicable in the Mid engine transaxle application.
http://64.226.197.185/Paragon/General/Fluids/transaxle_fluid.htm
I understand why Redline recommended the NS lubricant. The limited slip additive can make the oil too slippery so the synchros won't be able to do their job.

No, Steve. That's what is so aggrevating. If they would just come out and give the spec it would help. I suspect that GL-4 may work, as GL-5 is intended for "hypoid ring & pinion", which the V8 doesn't have. But the Redline reps insist on the GL-5 75W90NS for some reason. Maybe they're worried about liability for an expensive F-gearbox if their GL-4 causes a lubrication related failure. Just a guess. |

Joe C. -- Some of us do have "rear ends" (i.e., hypoid bevel gears) in our gearboxes so we're stuck with the GL-5 gear oils. On the transverse-mounted V8s (with helical ring-and-pinion diff gears), you probably do have the option of using a GL-4 gear oil. I checked my 308 literature and couldn't find any GL-4 or GL-5 recommendation (just "AGIP such-and-such") -- anybody ever come across a specific GL-4 or GL-5 spec in their 308/328 documentation? |

Thanks Hans, I read more of Redlines literature and it says that 75W90 may be required in those limited slip transaxle applications to prevent limited-slip chatter.
Many in this thread are reporting that they are using 75W90NS which is similar to the MT90 in that they both don't have a limited slip additive. Perhaps the GL5 rating of the 75W90 is an attraction.
I use 75W90NS in the rear end of my Capri race car which does have a limited slip. Of course, I don't care about noise and I prefer the additional limited slip bite I get w/o the additive.
When I change my trans oil the next time, I'll probably try the Redline 75W90 with the additive. My Ferrari currently has a standard limited slip gear oil in it right now, and the limited slip is even tighter than my race cars!

Also, Joe, remember that the F-gearbox contains a limited slip differential, not just a transmission. If I recall the Redline literature correctly, they say NOT to use MTL in differentials.

Curious why everyone is using their oil more recommended for rear ends. Red Line does make an oil specifically for manual transmissions called MTL.
Here is a link
http://www.redlineoil.com/redlineoil/mtlti.htm
I use it in my race cars, it definitely helps the 'ol synchros hook up to enable fast shifts w/o a crunch.

It's been over a month since I put the Redline 75W/90NS in mine (no additive) and it's absolutely wonderful. I never even *think* about 2nd gear anymore... it's just not an issue. I wish I'd been able to do that 10 years ago when I first bought the car.

Dana,
Two others changed to Redline 75w-90 NS without adding the additive, I don't think it is necessary. In other words, whether you have enough "residual" additive or not, it probably doesn't matter....in fact it can be counter productive for the synchros making things too slippery. |

I installed Redline 75w90NS in my '78 308 two weeks ago and I noticed a pronounced change in the shifting right away. The shifting is lighter but more distinct. Before the change it felt like I was pushing the lever through wet concrete.
Lets hope it stay this way for a while.
As far as the limited slip additive goes, I had added 7 ounces of Trans-X on my last gear box change and I believe there is residual in the gear box now to alleviate any chattering. No problems to date in that respect.

Update:
I have been driving my 328 for a couple weeks now with the Redline synthetic 75w-90 NS gear lube and it continues to work perfectly. No cold 2nd gear syndrome, and I have NOT had any problems with the limited slip acting up. So I have not needed to stick in the additive. |

Funny you should mention Royal Purple. It is stocked at my local NAPA. I even have Purple stickers on my wall from the last trip to the drags.
Maybe I'll try that in the next few thousand miles if I have problems with the Redline.

I'm running Royal Purple 75-90W in my BB...
Between the gearbox overhaul last year, and the Royal oil...she shifts like a Honda (well..close!)
No problems cold shifting or with diff noises...

Anyone ever used Royal Purple? They make a product called Max Gear that is a synthetic 75w-90 (also available in 75w-130(!)). They claim safe for bronze synchros, meets both GL4 and GL5 applications, and (according to what I read on the bottle) works in both gear boxes and transaxles with limited slip. Saw it at a Napa Auto Parts store for only $6.99 You can do a Google Search to find their website... |

Hans, I am aware of the Swepco 201 but went with the Redline because it was available locally.
On another note; Isn't the Shell Spirax the 'new' stuff that is proprietary to dealers only? I heard FoS sells something like it for 28.00 a quart.
Of course FoS says if you don't use it you will compromise the warranty on your car. Another case of 'FUD'?

For the 550 and 575 the recommended gear oil is Shell Transaxle oil. This is interesting stuff and is only distributed in the 55 gal drums to the dealers. There is no smaller packaging.
It is a GL-5 75W-90. Like all others, at 212 F it has a viscosity of around 14. However, at 104 F it's viscosity is only 81. At this temp the Redline 75W-90NS is 96, the Mobil 1 gear lube is 106 and most others are 115 or higher.
On paper, the Shell product seems to be the best one. But in use it is stiff when cold. I am using the Redline 75W-80 Lightweight gear lube. It may be a little thin for racing but still seems thicker than needed for my around the town type driving. The case temp of the transaxel is only getting up to 120 F for me. This is indicitive of a low friction trans with little heat generation, a good thing. Remember, warmer parts wear faster than hotter parts, all other things being equal.

Well, after hearing that Ferrari does not recommend GL-4 and many GL-5's are not recommended because of it's corrosive properties (there may be parts other than syncros made of non-ferrous metals), synthetics still seem to be the best performer according to many on this site. I haven't seen anything negative about the Redline products either.
Just want to cover all of the bases on this car.
As far as finding another excuse to work on the car, I attribute that to my obsessive/compulsive nature (read as anal). HA

I have driven my 328 some more and it is shifting well even cold. The cold 2nd gear is gone completely. I used the Redline 75w-90 NS straight with no additives. Works fine, no diff chatter yet, and I WAS getting some chatter with Mobil 1. This was when starting out with the wheel turned, in first gear and accellerating briskly.... |

Oh Boy! Here we go again. I have the list of acceptable gear oils from the another thread on this subject though I think there was still a lot of controversy. There were still misgivings towards GL-5 grade oil. I am guessing the definitive answer has to do with WHICH additives are being used in WHICH brand. I keep seeing the consensus swinging back and forth on this.
So what is the 'bullet proof' acceptable gear oil that is not embroiled in controversy?

Do the 308/328 gearboxes have the old type brass synchros Fiat used in the 60s-80s or something better? If soft medal, then I've heard to stay away from modern gl-5 type gear box oils. They are bad on the synchros. GL-1 is still available and is much better on it. Even something like castrol gtx 20w50 motor oil is preferable to gl-5. (engine and gear oils have different rating methods so 90w gear oil is like 50w engine oil)
I've heard a lot of good reports about Redline though, including from a racer I know who also owns a transmission shop. |

there will be more engine oil in the trans then trans in the engine oil.
I was told be Ferrari to NOT run gl-4. I guess the trans fluid is more of a debate then when to change a t-belt. |

I just changed the engine oil and gear oil in my 308 this weekend. The engine oil was definately 'darker' than the gear oil. The gear oil was translucent amber, not looking much different than the new gear oil out of the bottle. My guess is if a car has a bad case seal between the engine and transaxle the engine oil and gear oil would tend to show the same color (or similar). Taking a wiff of the engine oil is a quick way to tell if there is gear oil in it. The stench is unmistakable!
I am now using 85W90 GL-4 gear oil with 7 ounces of Trans-X limited slip additive. The car shifts great! 1-2 shift is light after a slight warm up.
Just for the record, I read the back of my GL-4 oil and it specifically stated that it was safe for non-ferrous metals.
In comparison, I read the back of the GL-5 oil and it has Phosphoric acid and Alkiline salts as additives. If there are any non-ferrous bushings or retainers used in our transmissions I would imagine they wouldn't hold up well to these additives.
In addition, I don't imagine rubber seals would hold up well to Alkiline salts either.
I probably should have held off on the limited slip additive but didn't think about it at the time. My own feelings are, if the car shifts good with the additve then I would feel better knowing the LSD isn't chattering.

Dave,
quote:BTW, Matt, how common is the failure of the shaft seal between the engine and gearbox? That is an interesting thought, but how would you know there is a problem (oil testing?). Also, why would the oil go toward the gearbox and not the other way around? hmmmm. I don't know if that is my problem or not, but if it is, it seems like a pretty involved fix. Seems like it would be better to just change the gearbox oil twice a year. :-)
The shaft seal is a common fix on the 3X8 cars. I am sure oil goes both ways but it is not a lot in a short time. It's a little volume over time. It's only something like $250 to fix. I recall I paid $268 for my repair from Ferrari. the Part was $18 and 2 hours labor. According to the Service Manager, He has never seen a 3x8 that did not need it fixed or has not had it fixed in the past.
Next time you change your oil, look for engine oil. You can get it tested. Sometimes if you have not changed your trans oil in a while you can smell and see it.

Dave--in the previous thread, one Chatter rec'd adding about .5 Qt of the the Red Line straight 75w-90 if there is any chatter. I believe that the rear label of the NS also says to add another Red Line additive IF that occurs.
A friend with a 328 just changed to Red Line 75W-90 as well ( w/o the additive or 75W-90) and reports great results, w/o any apparent chatter. |

A tip on changing: Sometimes the fill plug(s) can be a little stubborn. So open them first before you open the drain plugs, just to make sure. This way you won't have an empty gearbox with a stuck fill plug. |

I'm back and the shifting is fine, even when running to redline on the 1-2 shift. I'm not sure about the fluid color versus what it looked like before it went in. The Redline product appeared a bit golden in color going in. The may be some mixing with motor oil, but I don't know. My oil consumption is not excessive, around 1 quart in 1500 miles or so. The procedure is a bit messy at Matt says. Complete instructions are available at www.expensivecar.com There are several tech tips there.
Good luck all! I am happy for now. Will keep you all posted on any further changes. |

When I went to Redline 75W-90NS a few weeks ago it was IMMEDIATELY better shifting than with Mobil 1, and had ZERO cold 2nd gear problem, which had still be moderately evident with Mobil 1. |

I've been using REDLINE 75W90 for 3years now with no issues. This was recommended by TRUECHOICE andis the obvious choice if You visit the REDLINE website.

Mike,
It is a really messy job unless you have a long clear tube and a forgiving wife for making a mess in the garage.
First.
raise the car on jack stands and make sure that the car is level..
Using a 10mm allan key, Drain the trans oil pan and the clutch housing.
open the horzontal filler.
close the clutch housing and transpan
now, Get a long clear tube and snake it from the top of the engine into the transpan.
Fill with 4.3 quarts of oil or until it starts to come out. Do not worry about filling the clutch housing. The main pans feeds oil to that area.
Close the transpan filler.
Warm-up the car has normal |

I currently have Valvoline in my car. It is not recomended and Valvoline e-mailed me that they do not have a gear oil suitable for a Ferrari.
However the car shifts great into second when cold!
I will change it as soon as the Auto Zone opens here with Redline. |

Dave,
Awesome! Do tell us how your drive went.
My shifting is definitely degraded, using Chevron LS Supreme. 5k miles on this fluid. My guess is, it's starting to break down and/or mix with the engine oil as Matt suggests.
I *definitely* need to change the gear oil soon.
Dave, could you tell us please where you sourced the Redline stuff from?
Also--since I'm learning here--could you give a general outline of a procedure to change the gearbox oil? I've exhausted the archives and still have no clear procedure. I also can't find the procedure in the workshop manual.
Very much appreciated.
Happy shifting!
--Mike

I don't remember the #.
I think 15k for gearbox oil changes is a touch long but then again I drive it a lot.
What color is your oil when you drain it. If it looks amber then it's getting mixed with engine oil at the shaft seal.
That could explain why it changes over time and miles. |

Al, the presumed issue with additives is that they make things more slippery, which is counter to what the synchros need, which is a little less slippery. That is apparently why the Redline guy is recommending not using any limited slip additive unless absolutely necessary, and then, just the amount needed and no more. Time will tell, but I need to wash all this oil and crap off me and go for a drive! :-) |

Matt,
I suppose the Mobil 1 would be fine too, if I changed it every 5k, but there must be something out there that will go the factory recommended interval.
Do you recall which Redline product you used? |

Anyone tried any of the metal additives-conditioners, like "Militec" or "ZMax", etc?
A Porsche guy told me he had rough 1-2 shifts and after adding Militec the tranny shifted smoothly.
I have used Militec in my other vehicles, including my old truck and am very impressed. After reading the threads on the F. trannies I'm a little nervous about adding anything other than specified oil to either the engine or tranny. |

Dave I had a similar issue with redline on my 308 a couple of years back.
A ferrari friend of mine recommended I try the GM gearbox oil. I have not had any issues with it. I change it every 5,000k miles which is about 4 times a year. |

Okay guys, confession here...I was one of the advocates of using Mobil 1 gear lube in 308/328 transaxles, I had heard good things about it both here and over on Ferrarilist. My current 328 was very hard to shift cold or hot when I got it last year, so I had Mobil 1 put in. HUGE and immediate improvement, even my mechanic was impressed (this was 9/02). BUT, in the past four weeks or so I have noticed a progressive worsening in shifting effort, and on a few occaisions a "crunch" when doing a fast 1-2 shift at 7,000 rpm. Not good. I was even getting a little limited slip "chatter" when accellerating hard in first gear while making a turn. So after watching/reading the previous thread, I changed my fluid out today to Redline 75W-90NS as recommended by several of you (no additive for the limited slip, yet). Immediate improvement! I just got home from the shop and need to clean up, but will properly warm up the car and do some fast shifts and let you guys know how it's working a bit later. The big question is will the problem return in the future? The Mobil 1 was in the gearbox about 8 months and 9k miles before it started acting up.... |
