swap 4l60E trans out of 1995 vandurra 2500 for 4L80E
Good day, i could use some advise , i would like to swap my 4l60e tranny out of my 1995 gmc vandurra 2500 for a 4l8oe from a 2003 1 ton pickup , any help on pitfalls and maybe opions on what torque converter would be greatly appreciated, coach

I edited the thread title so members would have an idea what you are doing.

You will need to change the drive shaft Yoke to 32 spline of the 4L80E and length of drive shaft will be shorter. I would suggest mounting the trans and measure for length

Build or modify a crossmember for the mount

There are wire pigtail adapters available to convert from 4L60E to the 4L80E , you will need the PCM re-programed for shift sequence of the 4L80

Depending on your engine size, there should be a flywheel available to use with the new trans combo
