So, transmission #8, without warning yesterday on my lunch break went into fourth gear and will not come out of fourth gear. You could shift into neutral and it felt normal, but if you were to release the clutch, it was like it was stuck halfway between being in gear and neutral, and would stall the engine. The only gear that you could put it into with the engine running was fourth and fifth. You could put it into all other gear positions with the engine off. This transmission didn't feel great anyway as it was very "notchy". As it was the middle of the day and I've yet to replace the engine in the P5, without a way to get to pick another unit up, I canabilized the P5 for its transmission and installed it. From start to finish, including removal of the P5, removal and replacement of the MSP transmission, oil change and straightened up a few things, it took 4h23m18s.
Transmission #9 is installed... I'll actually hit double digits soon....
