Question type: General

Replacing transmission in 2003 Chevy
Blazer extreme 4.3 2door 2wd need to know
what I'll have to do to make it work because
the factory tansmissions are junk and I won't
put another one in it I've went through 2 in
the past year and I don't hot rod it at all

1 Answer


an older TH350 needs a vacuum modulator and a kickdown cable to shift, that's not going to be possible on your 03 truck, which is set up with a TV cable. I assume you're trying to get rid of the 4l60e?
