I keep a bottle of White Out Correction fluid in my work area to mark everything that I disassemble that has any question as to the need for an exact repositioning during reassembly. It has saved my ass many times and countless hours of lost time. You know what correction fluid is, It's thatwhite stuff you see all over a Blondes computer screen. |

Thanks for the answers thus far. There have been multiple references to the fact that I was probably in second and not first. It 'felt' like first but I can't swear to it.

Ckeck out pages E21 and E22 in the 308QV/Mondial workshop manual.

If it is selecting second than that would probably be the culprit Drew. Mine was out of adjustment just slightly so I adjusted it right, I was stupid though and didnt mark where everything was before I started, so I spent quite a few hours getting it right (because I couldn't see inside the trans because the cover was still on.
Andrew if you get it to go into this forward gear (in the reverse spot) just go around the block and you'll be able to tell what gear it is. |

Do you guys think that it just maybe as simple that the shift linkage adjustment between the shifter and transmission has gotten a bit loose and rotated a couple of degrees. You try to put it in reverse but actually are selecting second. You can't select reverse because the shift gate is preventing you from rotating the linkage all the way counterclockwise.
I would remove the 2 screws holding the shift gate and see it you are able to get it into reverse without the shift gate by rotating the shifter slightly in the countercloskwise direction (towards the driver). If this works its not that hard to adjust the linkage which is located under the car before it enters the transmission. It takes a little bit of time but if you're "handy" it's not too bad. |

That's correct. The bottom oil pan with all the nuts. |

when you guys say the transmission cover do you mean the one under the car next to the oil pan? I was going to change both of those gaskets (oil & trans) soon but I also think I'm going to have to do some adjustment for a similar shifting problem so if this is the cover your talking about I can do both things at once.

To put the balls and springs back in, use some wheel bearing grease around the balls and springs and into the bore and the grease will hold them in place. |

I second Joel's advice about the little springs and balls that drop out from the trans. case. They locate the shift-fork shafts when they are moved to select a gear. I CAREFULLY stacked them onto the cover and GENTLY offered the cover to the trans. case and into their respective holes. Took me two attempts... |

After thought, when you pull the transmission cover there will be three springs, three small balls , and three guides that will probably fall out to the floor. Dont worry. There is a place for them that is very obvious. They simply hold the shafts in place. |

This exact thing happened to me. I left town and had someone watch my house for me. When I got home and drove my car it did exactly the same thing. I suspect the fellow was acting like he was in a race in my garage. Shifting and such without the motor running. I had the garage door locked so I know he couldn't get it out. Remove the transmission cover and lie under the car and have someone shift the car. You will see that the shifting finger that slides between the three slots that select which shaft it is going to move is out of adjustment. In nutural it will need to be set to move the middle shaft. This is very difficult to explain but once you look at how it shifts it makes sence. One of the shaft shifts first and reverse, the other 2 & 3 the third 4 & 5. The whole job took less than 2 hours. Plus you will get to see inside the transmission and understand how it shifts. |

Andrew -- how do you know that it's 1st gear and not 2nd gear that's getting mis-selected? Bret's point about the different directions makes me think it's 2nd. Also before investing in a shifting fork "adjustment", you (or like Bret said, your mechanic) should maybe ensure that:
1. the two rubber "silentbloc" bushings (one in the tunnel, the other outside) in the linkage between the shifter and the forks in the gearbox, and
2. the engine mounts
are in good shape. Just a thought... |

Based on your other post about the cost of labor in New Zealand, just have your mechanic do it. If he knows Ferraris than he'll be familiar with this procedure. It's not really all that hard, it's just time consuming and can be frustrating (especially the first time you do it). And then there's always the thought of "Did I adjust it correctly" when go to first engage a gear with the engine running, waiting for a cataclyismic explosion with parts blowing out from under the car and through the rear bonnet. I only fooled around with the trans once and in the end it came out real nice, next time I'll have it easier. |

Yeah the forks and/or the shifter itself (ie the lock nut underneath and the shafts situation in reference to the trans) need to be adjusted. To adjust the shift forks you need to take off the cover (I haven't had to adjust them yet, but Peter will know about them). The shaft I can tell you is a b#tch to adjust if you lose your place of where it was in the beginning (unfortunately I found out the hard way). I think with a little mechanical inclination this could very much be DIY type of thing, depends how much you get into working on your car. What's the worst that could happen anyway, blow the trans...
I'm trying to picture in my mind what's happening to cause this back in there. When it goes into first (when trying to select reverse) is the stick hugging the left or right side of the gate, or right down the middle? Can you avoid the gear if you hug a certain side? First and reverse are on the same fork, but different directions. |

Hello all
Today I experienced a problem on my Euro glass 308GTB that has happened about 4 or 5 times in the last 4 years. It has been so intermittent that I keep forgetting to do something about it.
After a long hard run I can not select reverse. Either:
(1) The gear lever will just not go in, or
(2) It goes in but first gear is actually selected instead (That was fun the first time it happened)
Someone said to me that I probably need to adjust the "gear selector forks"
What is the procedure for doing this. Should I see my mechanic or is it somthing an average DIYer could do?
Cheers
