1badshelby Posted November 26, 2011 Report Share Posted November 26, 2011 I JUST got done with my install on a customers 2011 GT500 vert, i went with FB Performance Tansmissions,,, 800-769-1118, 4R70 complete kit, and other than not having cruise control no more, i see no problems with the kit,,,, until someone figures out how to make the 55r bullet proof, the 4r70 is the best choice.... one thing that needed changed out was the hard dipstick for a Lokar flexible one, which made a huge diff on the ease of the job The cruise control is one of the remaining issues I am having...it works until you go down hill, then it will drop out. Also my nav unit no longer works...can't figure that one out just yet. Mike Link to comment Share on other sites More sharing options...

Hooper T Posted July 15, 2012 Report Share Posted July 15, 2012 A 4R70W is your best choice. That way you still have overdrive for road trips. And with the auto you will run quicker and more consistant at the strip. Heres a link on how I did mine: www.westcentralauto.com/gt500_trans.htm What Blower is on your car?
