shifting issue

'97 f-350 pick up, auto, aux. cooler with fan, maintainced spring and fall with synthetic fluid. Was shifting hard actually more like jerking as shift, 1-2 and shuddering the whole truck 2-3 when under load, ie towing or bed loaded heavy, never problem with o/d.
Did dp/exhaust and noticed shifting changed, feels like I think it should.
now bigger problem... was towing 1800lb trailer, and 4800 lb skidloader about 65 and got on it as started up incline, trannie lost OD and redlined. I hit neutral, OD off button, back in D. Worked fine to jobsite and haven't towed in OD since. IS this a sign the trans is going or just a hiccup?? I think the truck is scheduled for maintance 11/2 for the trans.
sorry for long post.... tia

im not a tranny guy, but my best guess would be a slippage issue with the torque converter while towing in OD causing lots of heat, thus your problems. Im just specualating based on my understanding (which is limited) of trannies but its an idea to start with

will the tq convertor still get hot even with the cooler fan on and temps reading 150-165ish? I generally don't tow in OD but I was going fast and running late... cuz I think I remember hitting OD when 3rd reached about 3grand on the tach

yeah auto trannies scare me, just worried about having it implode in the middle of a snow storm!! Had it happen about 5 too many times when we still ran Chevys.
