kaze_v8 Posted August 14, 2015 Report Share Posted August 14, 2015 Interesting. I mean are there any real benefits from the 6 speed to being with? Quote Link to comment Share on other sites More sharing options...
1BAD2K Posted August 15, 2015 Report Share Posted August 15, 2015 That's for 07+ trucks that didn't come with the 6 speed. I would LOVE to do a 6l90e to have that low first gear and that awesome OD for highway cruising, but it would be way too much $$$ Quote Link to comment Share on other sites More sharing options...
SuperSportSilverado Posted August 23, 2015 Report Share Posted August 23, 2015 (edited) I'm doing this swap on this new project truck I'm working on. Its a 02 Silverado ext cab I bought for $500! Not sure about the motor combo but going with a Speartech E38 ECM and 6l80. Good thing is since my 2011 is my drag truck with just about everything swapped out I'm using a lot of its stock parts on this older truck. Will see how it turns out Edited August 23, 2015 by Three6GMC (see edit history) Quote Link to comment Share on other sites More sharing options...
