Alright, guys I already have a 5.3 mated to th400 swapped into my 86 k10 chevy.Now I want to swap in a 4l60e. I want to know if I'm missing anything on my parts list:
-4l60e
-Wiring harness(junkyard, redo standalone) as I ripped out trans harness
-Some way to mate 4l60e to np 208?(suggestions)
-Length of th400 and 4l60e difference? I have adjustable Dirty Dingo mounts
-Suggestions for trans cross member situation
-Also, would my current th400 shifting linkage work with 4l60e
-And I currently have VSS hooked up to 208 would I leave that as is or redo?
Thanks

Not sure I would do that,you would be better off with a 4L80E unless you enjoy pulling and rebuilding transmissions,I'm sick of issues with weak *** POS 4L60E's in my Wrangler and thinking of going to a TH400.Advance should have an adapter ring for either trans,you probably need a crank spacer and bolts and your vss should be fine where it is.

I won't be using the truck for off-roading as much. I mainly use it for school, I commute 100 miles round trip m-f and just desire the overdrive and better fuel economy. Also I got estimates of $900-$1300 for a rebuild around my area which is crazy so I thought id bite the bullet of the swap. This 4l60e will take almost all town and highway driving with little to non off-roading.
