Hi, Yes I remember at the start of working with the PTU'S all the literature saying it only worked up to 4th gear, but I've been on road test with the diagnostics connected and the PTU stays in 2nd gear whilst 3rd,4th and 5th are engaged at the rear. The clutch pressures are active too so it's not just like it's engaged ready to resume it's duty if you happen to drop back down to 4th. It was a surprise when we first did a road test and found it. Cheers Martin
Engaged at 5th...I'm truly learning something new everyday. I wonder what's the reason Ferrari could not be more upfront about it.
I have got a Lusso in for repair on Wednesday, I'll do a little video of the diagnostics and upload it. I agree with otakki there is no reason to hide the fact it's still operating, it would be good to use one on an open slippy surface to see it's effectiveness through the gears. My test is from standstill putting one side on grass one side on the road, pull away quick and make sure the front clutch pressures ramp up fast.
Maybe an easier and safer way is to get all 4 wheels off the ground with a lift, and go through the gears and see.
We tried that, and even with traction control turned off it still put a fault light on the dash for the abs and traction control.
I can personally recommend Martin and Simon. For there excellent work and service rebuilding my own PTU. More than an few thousand miles ago. Great service, very knowledgeable and friendly.
Hello, I sent one of my exchange units to Utah yesterday, once the customer has it installed I will ask him to come on here and review his experience dealing with us. To answer the question about the difference between my repair and gte's I will have to wait until the exchange gearbox comes back because the customer had his done by them previously. Thanks Martin
So for US folks looking to replace a PTU, what is the best option? I've heard of three but I do not really know the complete difference in what each one does to circumvent the failure. - Simon Furlonger (EU) - GTE (USA) - FErnie (EU?) I'm starting my initial preparation for doing this job as my PTU reservoir has been running dry pretty fast after fill-ups. The JOY!
I don't know about GTE in the US. But I did a summary of the differences in the UK options before making a decision. My recommendation having been faced with the same decision is SSautotech and Parkes Performance ( FerrariErnie ) on the forum. Furlonger is a seal replacement, SSautotech / Parkes is a proper rebuild and replacement of the weaker areas of the box improving it. Martin and Simon are passionate and clearly care about the service and quality they provide. I was and am very happy with the outcome. Thumbs up. Oh and no affiliation or benefit from me recommending, just personal experience.
Just for reference, there is an official PTU repair kit now listed on Eurospares. https://www.eurospares.co.uk/Ferrari/FF/FF_(RHD)/PartDiagrams/0027/PTU_REPAIR_KIT
For those who have gotten their PTU replaced with a repaired unit, what type of costs did you pay on the labor side?
I would be interested if anybody has ever serviced the PTU on their own. Where are the drain plugs for the oil and for the hydraulic fluid? I see where you put in the hydraulic fluid, but where do you add the gearbox oil?
Yikes. Was concerned about my hydraulic oil level, wanted to check it. Took to my mechanic. It was about a quarter low under the marking in the lower tank. We also found some leakage from the PTU drainplug/washer area that had accumulated on the lower body panel. 2014 FF with 24k miles. Okay, so, one might think if the hydraulic fluid is low, it could have only gone one place = leakage into the gear box oil. Correct? I don't think there is any way that this fluid evaporates or can be lowered otherwise. We are going to change out the PTU oil, obviously have new drain plug and washer installed to prevent leaks. Top off the hydraulic fluid tank to its marker. Find out if someone can test a sample of the drained PTU oil and see if hydraulic fluid is present. Fingers crossed.
Anyone know much about this company in US that repairs PTU? https://eshop.gte-engineering.com/products/ferrari-ff-ptu-rebuild1
No picture of the drain plug, there was a small amount of oil that it gathered on the underbody panel underneath the plug. Not a whole lot, and nothing on my floor ever. The hydraulic fluid is supposed to be measured at 1 L at the normal fill them out. They had to add 1/2 L to get it back up to the mark on the tank.
https://www.parkesperformance.co.uk/2022/02/modified-ferrari-ff-gtc4-lusso-ptu-rebuild/ This seems to be a better option. Apparently they redesign several flawed components so it allegedly fixes the PTU forever. Has anybody got any feedback to share on them? It would be nice to see that repaired cars never failed again, and compare that will swapped/rebuilt units by Ferrari or other parties.
