anybody have any ideas? i made a road trip in my 94 cc idi turbo with a e4od today. i went to michigan with a 14,000 gvw equipment trailer and picked up a john deere 60 tractor roughly 6,000 lbs plus some extra rims and tires and a few other things. trailer, tractor and all extra's was right around 9,000-10,000 lbs. everything was ok except the torque converter starting unlocking, driving down the road in overdrive, unlock for about 2 seconds than lock back up. well it won't lock up in low gear when taking off from a stop, and at low speeds it doesn't want to lock up at all in 2nd. the fluid is fresh about 5,000 miles since it was flushed, and at the same time i put a rv trans cooler on it so the trans is not getting to hot. anybody got any ideas? could the speed sensor be messing with it? let me know what you guys think. thanks, pete
