What tuning program will you use?
Are you swapping a 4L60E or a manual gearbox to a 4L80E?

All my best,

Steve

~ The wiring harness, and harness adapter from speartech. The main 4l60e harness plug will not work with the 4l80e. Speartech has and adapter the plugs into the 4l60e harness then plugs into the 4l80e. The other harness that comes with the kit it the VSS plug. The 4l80e has two VSS senors on the drivers side and the stock 4l60e only has one. You will have to connect this to the actual PCM its self. then plug the new added harness into the FRONT VSS. If you plug it in the rear you are going to have idle problems. (been there done that, lol)

Yeah, there's a great writeup/sticky in the Automatic Transmission forum that details everything needed, it was really helpful when I did my '80 swap.

...and yeah, HPT makes the swap easy and has great customer service to boot !!

Cheers,
Rob (Bad30th)

I am having problems with that conversion. After everything was installed and programmed I am getting a transmission hot as soon as that happens it raises tranny line pressure and shifting gets horrible. We scanned it and tranny fluid temps are below 180C, changed the harness that reads the tranny temps (it was leaking) and still.

any help would really be appreciated going nuts with this thing.
