A new and more affordable 4l80e adapter harness

[Frost]

LSxTune is happy to introduce our new 4l80e adapter for 99-02 F-bodies that are swapping out their 4l60's for 80's. Our M6 harness is in testing now, and this post will include the M6 version as soon as it is available.

Our trans side conversion harness has high temperature fiberglass sleeving protecting it. The VSS sub-harness uses clean-cut braided sleeving.

Let me know if you have any questions. PCM programming is available as well.

Dealer inquires are welcome as well. Thanks for looking.

TTT.... I need a tester for my M6 to 4l80e swap harness. The 60 to 80 harness works well and has been selling for a month or so now.

If you are going M6 to 4l80e, holla and I will give you a great deal on the harness if I can get some feedback from ya.

98s can't run a 4l80e with their PCM. He has to buy a standalone controller for the trans($$) or re-pin his harness and swap PCMs with a 99-up unit.
