brobradh77 Posted May 16, 2007 Report Share Posted May 16, 2007 I am no mechanic but as long as you dont have some hand held tune or any tune at all other than stock that firmed up your shift pressures I would think you would be just fine.

Schmids5.3l Posted May 16, 2007 Report Share Posted May 16, 2007 (edited) You should be OK, I asked this question a while ago. http://www.silveradoss.com/forums/index.php?showtopic=33403 Scroll down to post #8 by P. From your sig I guess you're still runnning the stock tune, so you should be fine.
