Before attaching the automatic transmission assembly to the engine, the engine turns fine. Once I attached the auto transmission, it does not turn. There is a 19mm nut on the main pulley coming from the cranckshaft, I just tried turning it using a 19mm socket and it would not budge. The auto transmission is in Park positiion. After attaching the drive shaft to both sides of the transmission, I tried turning the wheels and both sides turn freely and smoothly.
Let me pull out the transmission/engine assembly and take it back to the shop that machined the cranckshaft and ask him to fix it. This will take me a couple of days and then we can close this session. Thanks.
