I sometimes have a problem with my transmission slipping when I put the truck in reverse when I am on a hill. It will usually ketch if I put it back in drive then reverse again. Anybody else having the same problem?

no, but I think the TCU could be adjusted a little. It tends to not want to shift.

I also have fotten some really Strong jolts from the trans while it is doing its thing.

Yes, mine will hesitate a second before dropping into reverse. occasionally and it seems to be random not associated with length of operation, temps or incline. It hasn't been a real show stopper for me, but I'll mention it at 22000 miles.

Same here. I wouldn't call it "slipping" but it sometimes takes a long time to shift to reverse. I'm talking a few seconds rather than a split second... Sometimes longer than others. If I get in the fuel before it's finished it will jolt when it finally shifts.

I haven't fully decided yet, but I think if I am slightly rolling when I shift, it takes a long long time. Seems to be ok when I'm fully stopped and on the brake.

I know this post is old, but mine is now doing the same thing. 11k miles, mostly highway, and it started not backing up out of my driveway which is something of an incline. It will rev up as if it's in neutral, even rolling forward as this is happening. Sometimes it will catch and start reversing normally, after which the check engine light comes on for the next 3 stop/start cycles. Dealer couldn't replicate the problem, but was told by Chevy's technical support to replace input/output sensor which is embedded in the transmission. So they tore the transmission apart, replaced the sensor, and it still does it, if anything more frequently. Have an appointment tomorrow to recheck it, we'll see...
Anybody else had this since this thread was last posted in?

Just an update in case anyone is having the same issue... Transmission Control Module now replaced, after which truck would not shift into any gear. They have now gotten it to shift, and the reversing problem is no better than before.

Hi Aiden.
Did you have any luck fixing the issue?

I know this is a dead thread but I found it while searching for info on the same problem and I figured I'd update. My problem was, when parked nose down on an incline (my driveway) the truck would fail to go into reverse from startup. Shifting from drive to reverse a few times would usually get me out as I worked towards getting the tuck horizontal. The dealership initially could not recreate the problem until I showed up to do it for them. The truck must be parked nose down for a minute or two to recreate the problem--which I did and the tech got it immediately. The tech said that the transmission fluid was all draining toward the front while parked and that, combined with a senor failure, was causing the problem. He had me keep the RPMs high while attempting to reverse. Eventually, the car jolted into reserve and triggered the check engine light. This allowed the tech to download the error codes to help identify which senors are bad. I'm taking the truck back in a few days for them to isolate the senor. I'll report back then. For now, parking flat or nose up is the workaround.

Interesting. Glad you were able to figure out the issue and get them to see the issue in action too so that they could help you.
