I have a 2007 F150 5.4 with a 4R75E trans that I just finished installing a rebuilt 4R75E today. Is there a relearn process that I need to do? The transmission I put in was the same as the one I took out except it came out of a 2008 F150 and my truck is a 2007. I heard about the relearn process but trying to find out more. Please help. Thanks in advance.

 

Just clear the PCM by disconnecting the battery and drive it normally.
