Rob Posted June 9, 2007 Share Posted June 9, 2007 A friend of mine stopped by the shop tonight wanting to know if I had any advice on the problem with his air shift six speed trans. With the air built up you can select the low range and sometimes you're in low, sometimes you are in direct. Reverse seldom seems to be selectable. With the engine shut down, and the shifter in the neutral position, flipping the button gives the seemingly appropriate sounds from the air shift cylinders at the back of the transmission. Every now and again, reverse will fall in and you will have all five speeds. If the splitter is shifted back to neutral along with the shifter handle then both put back into reverse, it is probably going to move the truck forward when you let the clutch out as reverse takes several times to get in. The truck is a DM series, (1986) with a 300+ engine, and is a roll off truck. It has seen some severe duty through the years and runs very well.Any ideas??Thanks,Rob Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.
