What is the differance between a gas 4l80e and a diesel 4l80e?
I have a 80 Blazer I am going to put a 2000 lq4 6.0 in and i found a good deal on a 98 4l80e from a diesel truck and i am wondering if it will work properly with the computer for the 6.0.

 

Id say they are the same trans. I have the 80E in a gas suburban...

 

i was told by a guy at a trans shop that they are differant. must be differant valve body or something.

 

Well, I found out the transmissions are the same, the difference is the torque converter. Yay for me, that saves me $300.
