<p>[QUOTE="25(2)+2, post: 1854964, member: 4147"]Manually downshifting is possible if the computers decide it is ok, and that may not work to your advantage. The one I had wouldn't force a downshift that would rev the engine over about 1700 RPM, so you had to have it in a lower gear before starting down or ride your brakes enough to slow the engine to about 1250 for it to work 'manually'. It beeped at you if it wasn't in the parameters to allow an upshift or a downshift. The only thing you could force it not to do was upshift,lugging the engine with the selector in manual would still cause it to downshift.</p><p><br /></p><p>I drove one for a year and 3 months, almost to the day. I now have an Eaton 10 speed, and I would rather drive that, anywhere. You don't always have to start in low, and you don't always get to high, but you decide where and when, not like that thing did when it missed a downshift with a heavy load on a mountain upgrade.</p><p> </p><p>We both survived it, the truck went to the auction, and hopefully whoever bought it has lots of money to try and fix it, and is in possesion of good luck, because that person will need both.[/QUOTE]</p><p><br /></p>
