Now you describe, for all intents and purposes, the box actually preventing the shift (unless very inappropriate force is used. But I have heard that in fact all Ferrari's with manual 'boxes are reluctant to shift into 2nd when cold. I guess I understand that this matter exists with the 308gt4 and the Mondials (prior to the final iteration - it being north/south engine/transaxle orientation).For that matter, also for all 308's too. including the max-1/8" relief hole old-way-of-dealing-with the issue. For those who sent private messages with warnings who admitted they don't know this gearbox, never worked on one, never seen one, never read an owners manual for one, maybe just keep your comments to yourself?Ĭlick to expand.I've read this with great interest. ![]() It's been done for over a decade on dedicated forums.Īgain this is a specific issue with this particular gearbox and I'm giving targeted advice for JUST this gearbox. This issue goes deeper on why Ferrari specced the factory gear lube they way they did and why GL4 is best for them and why GL5 doesn't matter with the lack of hypoid gears and the internals of this transaxle but I'm not here to explain that. Then they figured out MTL is thin cold but also works great hot AND doesn't cause extra wear so just do that. This is a snippet from the Ferrari owners magazine with a very respected Ferrari tech explained why the passages are too small for the oil unless it it hot and thin and how to drill it to get more flow from 15+ years ago. It wouldn't be BITOG without people with no experience with something becoming internet experts. Today, I've actually gotten private messages from people who have never worked on a Ferrari, never seen the inside of this gearbox, don't know what my owner's manual specs and why, and have told me I am wrong about the passages being too small.
