Default 4l80e question...
Someone I know has a 4x2 05 4l80e for sale and I would like it for a 03 5.3 LM7 I have in the works, question is will I have a problem bolting the 2 together and will there be any technical issues with the computer? I looked around and couldn't find an answer to this question... Thanks for looking!

Probably need to change out the internal harness and the Pressure Control Solenoid.

What vehicle is it going in?

You will need an 80e flex plate and crank spacer if you use the stocke 80e torque converter, you can use the 60e flexplate if you have a verter' made with a 60e bolt pattern.

I have not had any issues swapping early and late EPC's for 60's or 80's. Do you know something that I don't here? TIA Vince
