    Did you install the torque converter bolts?

    Is the driveshaft installed? Lol sorry just messing around now.

    As long as the shift cable is hooked up and all of the obvious things are installed it should turn the wheels even with none of the electrical connectors hooked up. (Aside from the range sensor, the engine won't start without that connected.)

    Are you able to turn the driveshaft by hand with the rear end off the ground and trans in park? Are you able to turn the driveshaft with the trans in any other gear?

    the wheels will spin while in park - I pulled motor and transmission together - I guess I will drop transmission and try again unless you have any other advice

    If its an open differential then the wheels will spin in park. Hence why i mentioned the driveshaft.

    If the driveshaft turns while in park then yeah the parking pawl in the transmisson is shot. Might as well just get a used transmission to replace it with.

    Very unusual that a trans would do that just from replacing the motor.

    The only other thing i can think of is the torque converter wasnt seated properly on the input shaft when installing the motor and they might have shoehorned the motor and trans together by tightening the bellhousing bolts while the converter wasn't fully seated.

    Doing that will destroy the trans fluid pump and that will cause your trans to not work at all.

    Whoa dude that was just a wild shot in the dark guess. Just an idea of what things MIGHT cause what you're talking about.

    Always go through the proper testing procedures before replacing parts. Otherwise its just guessing and you'll provably end up wasting your money.
