Yes, the 4L60E is a newer version of the 700R4, that is electronically controlled.

The 4L80E is a different trans.

BTW, I EFFING hate this truck...

Today the fuel pump died, leaving me stranded perpendicular to the road, as I was attempting to turn around. This pump has less than 30 miles on it.

This truck has been together for about 12 years and we have hardly driven it since it has never ran right. I think it's cursed.
