I'm running a t45. Bought the car with a used t45 in 2012 and immediately had the spare rebuilt with "good" parts (Zak at the t45 source built it). Installed that winter of 2012. In winter of 2018 I had been having trouble getting the car to shift if we had slow double yellows but it would shift fine when back at high rpm....so I had it rebuilt again. Been fine since.

The t45/3650 are a absolute bitch to remove around long tubes.......but it can be done. We've pulled/installed several but it takes alot of maneuvering to twist/rotate to get the bellhousing up in there.
