4l80 SWAP PROBLEMS PLEASE HELP
 

HELP!!! Just finished my 80 swap and it doesnt want to shift into any manuel low gears when put in 1-3 and doesnt want to shidt when in DRIVE.

Im so lost idk what to do...

Such info, great details.

Way more information should be said to even try and get some helpful pointers.

What do you drive?
Have you done a segment swap via tuning for the 80e swap?
Is all wiring correct for the change?

05 silverado
did the segment swap via HP tuners and repined the wiring.
my speedo works.

sorry, im just really frustrated, im at a loss here...

Tell us about the trans. New? Junk? Rebuilt? Mods?

Did you do a pressure test on the pump?
​

Had it built with all new parts and shift kit.
had a local trans shop that was recommended to me build it. im hoping its not something in the trans...

Can you activate the solenoids with the scanner with the truck off but key turned to run? Did you wire in the input speed sensor?

How do i tell if theyre activated through Hptuners scanner? i was hitting the button to activate it, (truck was on though)

I used this 4L60E to 4L80E Conversion for the wiring

Turn the truck off with the key on and listen for them clicking.

ok thanks, ill give it a try. and if i cant hear them, whats that mean?

LEFT is my truck tune before seg swap, RIGHT is the file i used for seg swap
