LOOKING TO DO A BUILT MOTOR INSTALL IN MY TAHOE AND ALSO DO A TRANS SWAP TO A 4L80E. ENGINE WOULD BE CRATE FROM JEGS, 460HP AND REBUILT 4L80E...WHAT IS INVOLVED FOR TUNING FOR ENGINE?...TRANS. SWAP JUST A PLUG AND. PLAY?...TI

@BlackBearPerf can tune it with the existing ecm

 

[BlackBearPerf]

It's a straightforward swap as long as the engine is a Gen-IV engine. Transmission tuning would be required to control the 4L80E. We can easily accommodate that for you!

PLUGS ALL THE SAME?...BASICALLY JUST AN R&I JOB FOR BOTH THEN TUNE?...

i went from a 6l80 to a 4l80, different plugs for sure.

if he has a 4l60 going to 4l80, i think the plugs are the same but there may be a pin or two to move. or like BBT says i think you can command the solenoids to shift in the order needed in the tune to work for a 4l80

transmission is longer so will need driveshaft(s)

doubt it would yield better gas mileage tho, 4l80 has a tall 1st gear, less over drive .750 to .696 and a lot more rotating mass than a 4l60. but it would be miles ahead in strength
