I noticed this plowing yesterday and the day before. about every third or forth shift into reverse it will go in gear, and i'll strating accelerating backwards and it will all of a sudden rev up and slam in to gear hard. Now to clear up a few things first, when i plow i get to the snow bank, put in in reverse raise the plow and get on the gas pedal to start backing up. there is plenty of time for it to ship in this amount of time. trust me. especially becasue i've been waiting even longer now that it started doing this. My problem is that it doesnt' happen all the time. sometimes if i shift it the computer won't let the truck rev no matter how hard i push teh pedal, others it will rev up and slam in. so i'm not sure if its the transmission or ship delay sensor or somethign like that.

also, i've noticed that sometimes (random and less often) it will slip between either 2nd and 3rd gear or 3rd and 4th gear going forward. actually infact its happen twice that i'll hit the gas going down the road at about 30 or 40 and it will rev up and slam back in gear.

now i have to give props to the transmission because i've never seen one that would hold up to that much slipping with out blowing up, shortly after. this thing just won't DIE so i can show teh dealer.

If anyone can give any info on a simular problem let me know, if things tranny goes while its snowing i'm screwed and will make no money. sorry for the long post but i wanted to give info on whats happening so you guys and gals can give info. thanks, Rob

 

I'd take it to the dealer. You don't have to wait for it to die to get it fixed. If you do wait it almost certainly will die while you're plowing, because that is when it's working the hardest.

 

i know it sounds bad that i want it to die, i just mean that everytime i've brough it to the dealer for something that isn't constantly a problem, they say nothings wrong with it. because they don't get paid enough to drive it around for 20 or 30 mins and check it all out. i called the dealr today, and thye are going to look at it monday. any more suggestions of what it would or could be would be great. thanks!!

 

reverse and 3rd gear use the same clutch packs, possibly explaining the link between reverse and 3rd slipping-could be that clutch pack going bad

also, once you begin losing reverse (as in completely) your tranny is toast




check your tranny fluid and see what color and how it smells
