JerseyMonte Posted April 22, 2014 Share Posted April 22, 2014 What would be involved to replace my 350 turbo with a late model 6 speed auto trans. I have a 2:73 gear I have a Tahoe with the 6 speed and it has a low 1st gear ratio I believe 4.03 to 1 the Tahoe has a 308 gear but the tranny pulls the almost 3 ton beast very well Quote Link to comment Share on other sites More sharing options...
NewTimer Posted April 23, 2014 Share Posted April 23, 2014 You would need to fabricate a new tunnel that trans is huge also I am pretty sure you need a new flex plate and a stand alone controller for it which no one currently makes at this time, the last time I checked Edit: forgot about these guys, they make a controller for it. It has been around but I have never found much reviews on it linky Quote Link to comment Share on other sites More sharing options...
