:( I purchased my 1986 testarossa from a dealer in Jan this year and until now have enjoyed an amazing car that i totally love, then bang! (i knew it was bad). I am told the housing that holds the diff has collapsed, it happened as i was driving out from a junction the car give a bang and lost all the gear oil. I took the car to a local garage who told me that housing was split and advised me to contact the dealer as i had a 12 month warranty with the car. The dealer now says that this is a very common fault and he will not cover it because it is a ferrari fault and he would only cover things like clutch wear etc and estimates the cost of repair to be approx £6,000. Does anyone know of this problem occuring in early testarossa's or is the dealer trying it on?. Any info or sources for parts etc would be greatly appreciated as £6,000 is alot of money to me right now, on top of this i will have to send the box to england from ireland as i don't know anyone who might do it here and as goodwill the dealer says this is a good price to show he cares about his customers anyone else apparantely will ge £££'s more!:eek:

could be a few things rather than a split housing. Which side was the gear oil leaking from?

Check out this thread from another forum which has some pics and sounds like a similar problem

By the way, get a lawyer to look at your warranty. i would have thought major drivetrain problems would be covered

Cheers gma365, this certainly proves interesting reading. The oil came from the passenger side of the car (rhd car) and knowing my luck things will be worse than first estimated when they finally get the box looked at, i will keep you informed.

Ouch! I'm sorry to hear about that. The differentials on TRs are known to split internally increasing pressure on the housing until it ruptures and dumps all of the gear oil. If this is what happened, replacement of the differential is pretty much the only way to fix it. The differential problem was fixed for the later 512 and 512TRs. I would take a very careful look at that warranty as it should certainly cover driveline if nothing else. Good luck!

I've heard more stories about mainshafts snapping than the gearbox housing splitting. If the mainshaft breaks and there is very little "shrapnel" to contend with than it's not too bad. But if little pieces float around then it's a major expense. If the housing splits as in your case I'm not sure what can be done. Maybe welding the case and fitting new internals will be okay...but more often they replace the whole trans with the 512TR version which is much stronger. If a TR is abused with burn outs, and hard launches, eventually one of these two problems will occur down the road...pun intended. Thats why people (prior owners....NOT necessarily you) need to learn to drive these cars properly. Use just enough revs (below 1600) and let the clutch out from a dead stop as smooth and quick as possible. In my TR I'm able to almost "idle" away from a dead stop. No speed shifting is possible in a TR, so you must be deliberate and accurate, with the clutch totally disengaged during the transition. Lots of full-throttle acceleration in first gear is to be avoided if possible...or done sparingly. Once in second gear or higher full throttle is fine. I think I've heard that a 512TR gearbox installation runs around $15k or so here in the U.S....and will probably last forever unless you track the car a lot. The price you mentioned in your original posting sounds "reasonable" even though it is a ton of money. It sucks that the dealer is balking at honoring the warranty. I would at least explore some legal action if it becomes necessary. If they knew prior to selling the car that this was a "common Ferrari problem" and didn't disclaim this in writing, then you may have some leverage to get it fixed at a reduced amount. I would at least consult a lawyer about it. If the car broke at a location where it was not being subjected to high speed or abuse but driven in a conservative manner (no skid marks, no burn outs, maybe even a witness of the event) this would help establish a case. Please look into the situation and keep us informed.

Thanks for all your info, I certainly would have witnesses as i had just left a crowded place and some of them came to see the fuss when i pulled in of the road (it was a hotel) As you said about little throttle in first gear this pissses me off even more about the car because i can swear on a bible that i have never abused the car in any way or spun the tyres so it is even harder to swallow. I hope to know for sure today the results of my problem and i will take it from there. I will let you all know.

Finally heard today the initial results. Now i may have picked some of this up wrong as i am not mechanically minded in any way but they say that the crown wheel let go damaging the pinion gear and shaft. The crown wheel lost about 3 teeth and the pinion gear lost about 80% of its teeth. I was talking to the mechanic doing the work and he said he has never seen one do this before and will let me know what parts are going to be like to locate (new pinion gear is £3840 but ferrari might not have any left) and nobody will split a box so they are checking prices of a used one.When i mentioned the crack he said it definately isn't cracked on the housing but said the sump underneath might have a split but this is unlikely and not serious anyway but he promised to investigate properly for me. I will keep you all posted.

Sorry to hear about your tough luck. Man that sucks. For your parts, try Dennis McCann in Ohio. If he's got them he can ship them to Ireland.

You might try Ebay also. Funny the stuff you find on there sometimes. Some Ebayers don't like to ship outside the USA because of the extra paperwork. If you find that to be the case, PM me and have the parts shipped to my house and I'll forward them to you.

Best of luck.

tr diff problems

how many miles/k on the car . the box does tend to let go/split on higher milage cars . [broken pieces make more problems =$ . the best thing is to replace with an updated unit . standard on 512 tr . its not a good idea to max out 1st gear in any ferrari. i had to tell my boss i made a boo boo on a GTE once . i wonder if tire technoligy has any thing to add the the already problem . sorry to hear about it. cheers frank

Ditto. How many miles are we talking about on these Boxers and TR's when they are letting go?

There's every chance Eurospares would be able to help you, Speak to James Pumo and tell him Stuart from N.I advised you to contact him.
Also if you are anywere near Newry, a very close friend of mine (who has a TR) is a Ferrari specialist and charges excellent rates. He loves working on Ferrari's so your guaranteed the personal touch.

I hope you get things sorted ok. I know of 4 TR's in N.I

Thanks for all the info and tips guys, the problem was not the housing it turned out to be the crown and pinion busted, i don't know why because i never drive the car badly. I purchased a brand new crown and pinion and hope to be back on the road this weekend and can't wait. It took a lot of searching and i tried all the usual places but i found either they wanted to shaft me or thought i was stupid and would fork out crazy figures that they thought of (a phone call to the same place at a different time could show a price difference of £800-£1000!!) but i eventually found the right part at the right price in USA and it was delivered inside three days with a totally professional service.
I feel lots of people think that if you have a ferrari you are rich and will throw money at anyone but with me it is far from the truth and if you sit tight the right part from the right people will come to you,all you just need is patience.
