Sooo, I'm betting this question has been asked and answered on the forum somewhere, but I couldn't think of any search terms that gave me an answer. Anyway, when I'm parked overnight on a hill and try to drive off (and uphill) in the morning basically nothing happens. Or almost nothing, because the engine revs and the truck does actually start inching up. If the hill is very steep, I have had to roll back down and take a running start at it. I know the trannies on these trucks are lame, but I'm hoping that I'm not looking at a high dollar repair. I checked the fluid level and that wasn't the problem - any thoughts would be most appreciated. Cheers, Lock

I'm going out on a limb and maybe Richter69 will see this post, but I think there is a check valve on the outlet line of the tranny, maybe yours is stuck open or gone (some folks remove them for better flow) and if you park on a hill, your TC might be draining out while sitting for extended periods........

Or, maybe I am just fullacrap too. /ubbthreads/images/graemlins/biggrin.gif

Does this happen if you park completely level overnight?
