Truck Goes Fine Forward, Hard In Reverse

[ZackTeryx]

I had a very strange issue happen last night and I am getting ready to go out for a trip towing 15k. I went down to re-fill the fuel in the truck, and i was backing up in my driveway and it was backing up fine (idling), then it felt like i bumped a block or something and it came to a stop.

Then I pulled forward, got out to move the peice of wood or something i hit and looked, and there was nothing, so i got back in, put it in reverse, and it went about a foot and then it felt like the same thing. SO, I gave it some of the pedel, and it started moving, but then as soon as i let off, it came to a stop.

Clicked it over to drive, and it pulls forward great, but as soon as i go into reverse, it stops and when i accellerate, it feels like something is dragging.

Any ideas of things to check, i gave it a quick once over and even felt all the brakes, and one didn't feel hotter then the others like it was dragging.

That sounds similar to what my trans did to me. I was backing cattle trailer up into the barn when it started, went on a 700 mile drive the next week to college and went back into the driveway and couldn't get in. As long as I left it at an idle i could get a lil bit of a running start but if i got on the fuel hard the trans started slipping. Read that if ya put the T case into 4 low it'd back up fine and it held me from August until December when I was home again but I ended up replacing the trans. Hope you get it figured out.

I think mine is kinda opposite, It really feels like i am trying to backup with a foot on the brakes, or with a trailer hooked up. This was just the truck by itself, no trailer.

yeah, mine was doing the same thing but i had the trailer hooked up the first time it did it...then after the long drive it was like I lost reverse

hope you can find a different cheaper fix...but that's what happened to mine...did you try using 4 low and see if it changed anything?

I am going to give it a shot when i get home from work. I am sure its going to make it be able to backup at idle because its just doing more gear reduction to over power if its say the brakes stuck or something binding.

yeah, I have the E4OD...you have the 4R100 in a SD right? may be something else doin it..hope ya get it figured out

check your e brake system. something is loose and binding up when the wheels start moving the other way. happened on a truck at work yesterday, ended up being an e brake shoe that fell off.
