Firstly I’d say this is probably not the reason for your problem. However, a similar thing happened in my Australian Valiant at a shopping centre car park no less. The Borg Warner auto finally gave up the ghost and it commonly fails, I found out later, by not releasing a band or clutch (forget which one) when it is supposed to. Basically the transmission locks up internally. Lots of revs got me reversed out of my parking space (like the brakes were locked) but it would let me drive forward. Solution was a replacement box. Don’t forget that auto bands and clutches can fail as well. Easy to check by jacking up the rear axle and putting in gear.

Server Subject: [Chrysler300] 300H rough idle/ now about car "locking up". Some time ago, I moved my car in my garage and it locked up as though it had hit something when I moved either forward or backwards a couple of feet. Because I HAD to move it, I gave it gradually increasing amounts of throttle and it did move as though I were driving through locked brakes. Here’s where things are now: 1. Removed both rear drums, and found both rear brakes were normal (they were rebuilt a couple of years ago.) 2. Removed drive shaft and found a rear u-joint was worn but showed no signs of anything locking up.I could turn the diff input shaft either direction without a problem. 3, The diff was shipped to Randy’s for disassembly, inspection and rebuild . It was in good shape except the Power Grip clutch pack was worn (350,000 miles). 4. I spent a long time on the phone with Jeff Carter (who sold me replacement axles as mine were stripped or worn on the taper),and he suggested I check out the e-brake more throughly. I just now pulled that drum, and it looks just like it did when I put it together several years ago with new lining. It is also not my smoking gun. 5. Jeff Carter suggested I check for a broken trunnion pin on the front U-jpint, which I will do. If it still does this (no reason found not to!) , I plan on cycling buttons on transmission between 1 and D as that is a different fluid path and may show something. If anyone has any further suggestions , I would sure be grateful!
