Hi, I have a 1995 512TR with 16k miles on the clock in excellent condition.. full history file etc..

When you start the car from cold everything works as it should, all gear changes are fine, no issues. But as soon as the car has warmed up (approx 10-15 mins of driving) it becomes very hard to push into first gear, you have to use a fair amount of force, all other gears are fine, only 1st gear and only when engine/gearbox is warm. Another thing to note is that if you turn the ignition off and try first gear it goes on smoothly…

I have had the gearbox oil changed and the Ferrari specialist have tried some adjustments on the gate etc and they said all looks fine…

Any advice on what could be the issue would be greatly appreciated.

many thanks

regards Lee

Is clutch releasing fully .maybe the heat is causing air in the line to expand and not releasing clutch fully ..

It has to be relates to clutch not releasing (even TO bearing) since you are not moving (not synchro) and you had linkage already adjusted

Thank you I’ll ask the garage to look into that… someone mentioned changing the diff on another forum but my technician doesn’t think that’s the issue??

Got to be the clutch adjustment. Diff carrier is another issue, early welded ones break, you want a solid forged billet carrier. Modena and Paul Newman make them. Ask Paul, I just spoke to him about one for my 512 BBi. When he gets enough requests he will make a batch. I don't think it's related to your first gear issues but major major major gearbox damage if your diff carrier lets go.

Username Newman on this site, Paul Newman on FerrariChat. I don't believe he has a website. Many great threads on both sites of the full restorations he has done. Not every TR owner has the carrier fail, but many do opt to have the OE welded design replaced by Paul's or purchase a unit from Modena Engineering or others. My understanding is if the carrier cracks you risk major damage to the gearbox casing itself among other items. All very expensive compared to the carrier.

Ok thanks that’s great.. I’ll speak to my technician and contact Paul.

What I read is a very common problem, albeit it usually refers to 2nd gear.

The fluid channels about the 1/2 gears in the older models are a bit tight and cold fluid doesn't flow easy when cold. Bringing the car up to temps will make the issue go away.
Many of us struggled with 1st to 2nd and typically before temps get up--about 10 minutes max--just skip 2nd and go to 3rd when cold. Is this the issue? You state 1st. Perhaps it's only your model that has this. Others?
