bfletch7441 Posted February 4, 2011 Report Share Posted February 4, 2011 The newer trucks have : PRNDM for their gear selection. What is the M for? Ben Quote Link to comment Share on other sites More sharing options...
VermontHunter Posted February 4, 2011 Report Share Posted February 4, 2011 The " M " is for Manual Control .. Quote Link to comment Share on other sites More sharing options...
Shaun_300 Posted February 5, 2011 Report Share Posted February 5, 2011 Yep, manual mode. The newer style trucks with the 5.3 or 6.0L engines have the new 6L80 transmission which has a manual mode. You can put it down to M and use the toggle switch on the shift lever to change gears while driving. Quote Link to comment Share on other sites More sharing options...
Gator Posted February 7, 2011 Report Share Posted February 7, 2011 What Shaun said! I have used it in this snow, helps me slow down without using the brakes and running the risk of sliding. Also used it to keep my speeds down on slick roads Quote Link to comment Share on other sites More sharing options...
