Transmission Replacement Thm-700-r4/4l60

[ScottGriesser]

Hello, I have a 1991 Jimmy and looking to replace my transmission. It is on its second rebuilt and has lost overdrive. I believe it is a Thm-700-r4/4l60. Any suggestion on where to go for a replacement? I am located in the Denver Metro area of Colorado if that changes anything.

Are you looking for parts or for service?

My go to in the Denver area for service is Detroit Transmission off 52nd and Wadsworth. Not cheap, but that’s what you expect with 4x guys working 30+ years in the same shop

I am looking to replace the whole transmission and install it myself. Good to know about Detroit Transmission though.
