Are you SURE you got the torque convertor bolted up to the flexplate/flywheel?
It may seem like a silly question, but you wouldnt believe how many times i have seen this happen.
Lets get down to basics,,,if the trans was working fine before the engine was replaced, AND the convertor for sure is bolted, the fluid is full and the linkage is moving,,about all thats left is an internal issue inside the transmission. This just doesnt make any sense.
If you would like, i will opt out and see if another expert can pull something out of his hat :-)
There is a possibility that there could be a blown fuse, or a disconnected/faulty TPS switch (throttle position sensor) Check them both and let me know...
Let me know what you find please...I forgot to send you these diagrams.
Well,,,,,it looks like we have went as far as we can without the use of a scan tool to read diagnostic codes that will be stored in the computer. The scan tool is not the same as a "code reader" it gets into measuring applied voltages and line pressure activation. Sorry but i'll opt out and see if anyone else can perform a miracle. Best of luck my friend!
Here is a list of possible codes that will come up with the scan tool.
