Title: Overdrive Trans for 75 Blazer w/203 and 350 trans
Post by: scpscpscp on May 02, 2008, 06:34:06 pm

As gas continues to go up, I have finally decided to look at putting in the overdrive transmission. Question is, which one? I do not want to put in a computer assisted tranny if I do not have to. Is there a thread already on here to help with the installation, such as having to change the crossmember, etc. Any assistance helps. Thanks, Steve. ???

Did you try the search feature? The 700R4/4L60 is the cheapest non computer controlled overdrive trans.

Or one of these would sure be nice
