94 j30 infinity tranny will not engage into any gear.I replace the engine

[mel m]

its good,second tranny same thing? I pulled the engine and tranny out of the car to replace the motor,when i got the engine in and every thing hooked up ,i started the car and it started just fine but when i engage the tranny nothing happen.The tranny ran good before i took them out.So i bought another tranny and the same thing.Now let me say i have done all the normal things.I have pulled the engine and tranny 4 times to recheck myself and i can not see what i am missing.I have to say that im more of a engine man than a tranny.I throw my hands up when it comes to a automatic tranny.Now one thing that i think is funny,i can let the car idle for 45 min and check the tranny fluid it was not even warm.Some people said it could be the pump but i had one of the trannies looked at and everything was good.If anybody has any ideas,i will be very gratfull. Thank u.

Did you attach the flex plate to the torque converter ? It sounds to me like maybe for some reason you are not turning your pump and since i am not there to look at it we have a problem perhaps you can cam me and we can do a IM to figure this out that is all I can think of .
