Sam, has your mechanic indicated how much work it would be to just tighten the loose nut and replace the gearbox asis? Unless someone can authoritatively vouch that this problem won't re-occur in a new gearbox, it hardly seems worth the trouble to go for one, especially given that you were not experiencing a problem earlier. The risk with this approach is that there are bigger problems that will bite you soon, but the upside is that the repair may last you a long time. I'm at a similar decision point with my gearbox, but in my case significant disassembly is needed to replace a splintered bevel gear so the financials are different. |

Frank,
Nope, it's not exactly the same, you can;t use one out of a 348 & bolt it into a Mondial t or vise versa. Maybe the internals are the same, but there are noticeable differences in the cases & mounting brackets and such.

Guys,
You want the Mondial T gearbox, no problem
Ferrari NA has this item listed @ $9399.93
I can sell it to you for $6999.99 + freight
This is a brand new gearbox, with either 3 Point 0r 4 point mounting brackets, price is the same.
Delivery is about 4 weeks.
This will be coming out of Europe, FNA have no stock on either gearboxes.
Kurt.

Well,
the 348/mondial T has two crappy transmission problems. I know of 3 challenge cars and my car,one other and now Sam's car (it sounds like) which had improperly staked "stake rings" in the clutch shaft. This cases the shaft to move and the gears to collided causing knocking that sounds like a bad clutch T/O bearing rattle. Closer inspection through the bell house side inspection plate reveals often times chipped or scorred input shaft and clutch shaft gears. I do not think the housing is a problem. I did my rebuild and it is easy after I made some special tools and took my time. There is no FNA manual on this of any detail. Your brain and the parts book are your best weapons. If you take this apart I can give you advice. I did this over 5000miles ago and club race my 348. My gearbox is bombproof! At least two other cars I know have poor heat treat in the gear metel and one one gearbox the replacement gears were bad too! This causes disintegration of the gears like water spray on a sand castle. These are real events. I have seen one gearbox with internal castin flaw that caused the clutch oil pathway to leak into the gearbox oil. This last may be an isolated event. I'm in So Cal. and to my knowledge there is no one with extensive knowledge of these gearboxes. It takes time and or special tools to fix these. I think these are easy to fix. However, the time and concentration required is high and most shops need to turn out cars. You do the math and you can guess what you get. Find a guy who knows what he is doing who will take his time. There are FNA dealer guys who don't know what they are doing on this one too. Be careful or you will be repairing twice. |

billy,
any thoughts on rebuilding mine? My mechanic tells me that the nut that holds the input shaft inside the gearbox came loose and that coused some play in the shaft that wore through the bearing and caused wear in the housing and he feels that when he opens the gearbox there will be big problems as well so he feels best econiomical solution is a new tranny....car ran fine before clutch went so I am confused. with about 3 grand plus labor for the clutch and a new or rebuilt tranny being ??? plus labor with maybe new motor mounts I fear the car may be beyond economical repair ...I figure I could be over 10G on this repair for a car that is otherwise fine...getting concerned. Maybe towing it for a second opinion is worthwhile...I told the mechanic I am going to have to come down for a look before he proceeds. |

Nothing* wrong with my 348 g/box either, but it is a F car and there's always tomorrow!!!!!
*Apart from 2nd gear being 'not an option' when cold that is. |

Billy,
What makes you say that the 348 tranny is crappy. I have heard that they are very solid and I (knock on wood) havent seen any problems with mine. Just out of curiousity what parts went bad in the tranny? |

In seems to me that unless it has weakened the housing due to excess heat, that scorching alone should be no problem. Clean it off, have the clutch installed and drive. |

My mechanic tells me i should get a new gearbox for my mondial t...says there is "scorching in the housing" curious if anyone went through this or can give any advice...car was working fine going in and the car is in there for a clutch repair/replacement. |
