I've been putting this off since I still have an e-brake in my trail truck so it doesn't bother me right now...but that could change very soon. The last time out I was pounding on my truck pretty good. Everything help up very well. I went to put it in park on a downhill slope and took my foot off the brake to depress the e-brake (I drive two-footed when I wheel) and the truck made a clicking/whirring noise and started rolling forward. I figured no big deal, the park pawl is stripped, I can live it. I stuck it in gear, shut it off, and put the e-brake on. Later in the day I forgot about it and put it in park while pointed uphill, took my foot off the brake to engage the e-brake and then realized the the transmission was holding it's position... I don't know jack about the inner workings of an auto nor do I pretend to. Anybody have a clue as to what's going on? It's a 700R4 that was rebuilt a while before I bought it. I didn't think it could be stripped in only one direction unless I'm losing it. This truck/transmission isn't worth a trip to the shop if they're gonna have to tear into it. Any advice is more than appreciated.
