Re: Contact Bob Fernald. He's been building Alfa transmissions for decades.
Is Bob on this board?
I contacted Vick Autosports in Fort Worth (I'm up that way a lot).
They phone quoted $1000-1300 to rebuild or exchange my current gearbox since I will be removing it. They said I would have it back in about a week.
I have seen that people recommend them for parts, but I haven't seen a recommendation for their service. If anyone knows about them please let me know.
I also located a 260Z gearbox already rebuilt by the shop that used to do my work on Z cars. I can get it for $850 but I'd be putting another $300 into an adapter and then have to figure out the clutch and input shaft requirements. Also, since I don't have a CAD model of any of the transmissions, I don't know how much metal I would have to cut.
I will be replacing the clutch since the tranny is out. I thought about resurfacing the flywheel but I think the car revs out too slow. Perhaps a lighter (new) flywheel would be in order to go with the rebuilt trans.
And yes, I thought about the Z engine in the Alfa engine bay. Maybe if I had a spare car I would attempt doing that. It would sound terrific (very Ferarri-like) and would shift like butter at all engine speeds. Can't get the spare car until the end of summer though.
Thanks to all of you who responded. I appreciate the opinions and I didn't see any flames.
Last item...Does anyone have any 3D CAD models available (or know where to get them) of engines and/or transmissions, especially the Alfa?
If not, I will be modelling the Alfa gearbox/bell housing while it is out of the car. This will be in either Pro/E or Solidworks, but I can convert to IGES for those who may be interested. I would do the engine, too, if I were pulling it or had a spare to measure.
Keep the thoughts coming...I am learning a lot about my Alfa.
