I think I rebuild more "just rebuilt" transmissions (which don't shift properly/make noise) than I rebuild original transmissions.
Since the internal wear pieces inside the 05 are the same as the 03, I think I would have pressed the client to just use the 05 for parts and rebuilt the 03....making sure that "rebuilt" actually means rebuilt.

Just me....
The last thing I want is to right back here with a rebuilt transmission with a new set of issues.
Had this fellow reached out to when he was looking for a solution I would have suggested he send the transmission to you or have Howard Wright here rebuild it. He is factory trained on 928s.
I spoke with Howard at Sharks in the Mountains. He does not do rebuilds where he does not also have the car. He does a before and after drives. That makes perfect sense.
Well, it's done. A couple of additions to what changes with the swap.
You should plan on replacing the upper bell housing with a later version.
And the long bolts that secure the hand brake cable along the subframe are not long enough.
And a funny thing.
The 2-3 shift is really tight in the new transmission. How tight?
So tight that if you don't tighten the rear shift rod on the pivot tight enough will pull off the pivot. Luckily, it fell off a few feet into my garage. :-)
I took copious pictures along the way. I need to organize them before I post them.

A new synchro with a new slider are generally fairly difficult to shift, in this style transmission.
These transmissions are also very sensitive to what gear oil is used.
A few miles of upshifting and downshifting should loosen things up, if it was rebuilt correctly.
I am the owner of the above mentioned car. Happy would be an understatement. This car was the only 928 manual I have ever driven and the Clutch and Tranny were not good from the start. I still put 10k miles on it as it was. I loved driving the car but the tranny was really getting worse and I just adjusted to the lousy shifting and clutch noise. Finding someone to work on these cars in Alabama not easy. Kevin installed the tranny and new clutch. He then replaced the fuel lines and sent the
injectors off toe be refurbished, Unbelievable the improvement in low end torque. The shifting now is butter smooth and no noises. On my 240 mile trip home I had to learn how to shift this car all over again. Glad I had a windshield on the way home because my teeth would be covered in bugs.
Thanks Kevin!!

I don't know how this car performed off the lot, but this car has too be damn close.
It disappears under you. The torque is amazing. It loves to go fast. Don't tell my other 928s, but David's car is the nicest 928 I've ever driven. The gearing is perfect. Hard to believe it's a 4.5L.
I'm glad the owner is so happy, but I did nothing magical except replacing everything from the flywheel to the battery box and refurbish the injectors.
