915 Rebuild

[Wally]

Last year, the 915 5-speed in my 1303 with the 2,4 TIV performed excellent, but for the synchronisation of the trans itself. Its a mag-cased 915/40 from '76 with a 8/31 differential.
Shifting up and down to 2nd and 3rd could only be performed with a little time-lag or it protested by grinding..
This was not funny at the track and seriously annoying.

So, for this year I wanted to have the problem dealt with.
That meant either buying another - better - 915 tranny, having some-one rebuild mine or rebuilding this one myself.
Since another used 915 can usually not be tested in the car it came from, that would always be an (expensive) gamble.
Buying a rebuild one is also expensive: I think you're looking at 1.500 - 2.000 euros...and so is having a rebuild done by a good shop.

So, despite my deeply seated resentment of opening a tranny, I have just done that :
