Hello everybody, coming back after a 10 years hiatus when I sold my 550. Back then I did not participate much in the forum but I read a lot. I will try to participate more while I sort this new toy.
Red/tan (really odd color combo I know) 1989 30k miles, I bought it directly from a friend. Major service was performed last year. Car runs really good.
So will Testarossa's ever go up in value? The transaxles are fragile GEE I just can't figure out why these cars are languishing, while just about every other car is skyrocketing. Maybe it's because WE are the biggest group of self deprecating car owners on the internet. Does every post have to accentuate problems?
Every post?????? Give me a ****ing break. Have a problem with truth? New owner deserves a warning on a very expensive weakness. Put it where the light don't shine. Good God. Another ******* on ignore.
Actually the transaxle was upgraded with last major as a preemptive measure, it was an aftermarket one, I will check the records to see if I can figure out the manufacturer, if not I will ask him.
The upgrades are important and help a lot but by no means fix all its shortcomings. It is still not a transaxle to treat harshly. Its fragile no matter what updates and improvements its had.
How’s that? It is my understanding the problems with the differentials were it was welded instead of a one piece, of course I am not intending to do burnouts and/or dropping the clutch but how a differential can still be fragile with a solid piece of metal? Maybe the other pieces connected to it? Or the internals? Not debating, I want to learn
I never said differential. I said transaxle. I have been working on flat 12 Ferraris since before the Testarossa came out. These are not singular events. I kept pictures of representative examples. I have had a TR for over 20 years. I like the cars but every owner needs to know its a fragile transaxle. Not every picture is mine but I have experienced all on client cars.

gotcha Yes I’ve read about the shaft issue too, actually I’ve read an old post of you that you mentioned the shaft works as a fuse for the transmission So as long as the shifts are not aggressive the car can handle flooring it? Or any of those parts can fail with acceleration only?
the shaft will fail when accelerating very hard in 1st gear and shift fast into 2nd, of better push the clutch very fast. the shaft is turning itself when accelrerating and when you push the clutch the shafts reacts like a spring and can break. I killed alraedy with my competition 1 shaft. this has been alraedy much stronger than the thicker shaft and made of 1 piece, not 2 pieces as the original. now I have in a shaft from rob hayden ( australia, also a member here, but he is not making those shafts by himslef, may be MODENA from australia is doing? they also do very good diffs ) what can turn itslef much more around and goes back without breaking.
You are talking about the propeller shaft and not the transmission main shaft. The picture is of the main shaft, a vastly more expensive fix. Propeller shaft breakage is so common I didn't even put it in my photo array. In their sheer stupidity Ferrari in response to propeller shaft breakage they made the shafts heavier duty. That transferred the break to the transmission main shaft which was grossly underengineered.
Is there any upgrades (like the differential) that you would advised to be made as preemptive measures? Or a Better question is “what did you do to your own car”” Thanks
A differential and a Modena Engineering propeller shaft. His shaft is made like a spring so it winds up and protects the trans from shock loads.
I let produce mainshaft and layshaft with CP from a specialist in germany and never had problems again. but it was very expensive but those highest quality material you not need for normal aspirated TR serie cars
