4L65E Swap
 

Anybody know if I can replace the 4L60E in my 2007 GMC Sierra with a 4L65E from another vehicle and still use the computer in my truck, are they compatible? Also what vehicles do I find 4L65E transmissions in? Thanks guys.

The 4L60E can be upgraded beyond the 4L70E spec.
Check out PerformaBuilt Trans and look at their Towing Series trans.

They can also help with the advice on the 4L65E swap.

Here is some swap Information from a 4L60E to 4L65E posting


1) The tailhousing has to be swapped off stock tranny because the one that comes on the L65 doesn't have mounting points for the torque arm. (its 6 bolts and took me 3 minutes to do.)

2) the manual shaft (aka the shift lever) that protrudes out of the side of the trans and gets hooked to the shift linkage must be swapped as the Holden/truck style shift lever is too long and hits the tranny tunnel. it's pretty simple, it's just a matter of popping the pan off and working the lever out from under the gear selector (the ratchet thing that moves as you select different gears.), then putting the stock 4L60E lever in it's place. i let a tranny guy do this step just for the sake of him knowing exactly how to do it and it took about 10 minutes.

3) Should have the same electrical connector and plug in and go.

If you do this yourself, take special care not to cut the seal while putting the shaft back in the case.There is a sharp edge on the shaft. Deburr as needed.

Anybody know the code in the glove boxes for the heavier duty trans?
