7+ 4L60 To 4L80 Swap Wiring

I Plan To Use A.

I'm going to be running a 4l60e in the vehicle that i am using the tbi for. Now i have seen plenty of plug in adapters for a 4l60e to a 4l80e swap, but i am doing the. I currently have a 17 pin 4l60e was wondering what i had to do to get the 4l80 in as far as wiring.

I’m Currently Working On An Ls Swap In A 1998 K1500.

Each platform will be a little different; With everything pulled out, i measured a length of 27 from the transfer case. You should be able to run the ’08 harness provided you’re swapping in a ’95 and above 4l80e (though i’d swap in a 97+ simple due to design changes).

My Question Is, What Era Of 4L80 Will Work For This Swap?

The existing speed sensor wires from the 4l60e (purple/white and green/black wires twisted together) will hook to the speed sensor directly above the round gray trans connector on. As part of this swap, i'm replacing the weak 4l60 with a 4l80e. Today we wrap up the 4l60e to 4l80e swap with wiring and tuning options.

You Need A Tcm For A 4L80E, That E38/E40 (Whatever One It Is) Uses A Tcm That Communicates With The Pcm Via Canbus.

Get a wiring schematic and go wire by wire on your harness and match up pin by pin, wire color by wire color, to determine which. You will need the 4l60e to 4l80e. In this article, a fully built 4l80e from finish line transmissions will be installed in place of the 4l60e.

A Popular Swap In The Ls World Is Upgrading To A 4L80 Transmission From A 4L60E Or A 4L70E.

Its the part on the trans where the gear changing. I have the harness adapter already. Not sure why you're trying to swap a whole wiring harness for this, it's literally moving two wires at the trans plug and adding two at the pcm connector.
