Well ive been trying to install my stock transmission onto a 89 350 tbi engine i bought for my 92 camaro rs. And the problem I am having is that it wont go together as easy as the stock to the stock motor did. Also when i do get it lined up i have to use a couple of bolts to pull it together and then the torque conv. wont spin freely like the stock one. And yes the torque conv. is in all the way. Im not sure but every mechinic I talk to says that it should bolt up with no problem but in this case its not. If anyone has any idea they would be appreciated.

 

Flexplate on backwards?

 

was the motor from a manual vehicle? if so you will have to remove the pilot bushing or bearing from the crank. and you are sure the tc is in all the way you can't fit your fingers between the tc and pump?
