Mines done the same thing with 4 transmissions, new plugs + wires, fuel filter, tb cleaning, new lim gaskets, ported lim (not that that helps), and seafoam blah blah the works. I was convinced for so long that it was torque converter... but on the 4th one that'* hard to believe. I just deal with it now.

There were many Trans Chuggle topics posted in 92-99 on this problem in years past.

I just adjusted TPS. I think that didn't really 'fix' the problem, but it definitely hid it well.

I still haven't given the car a test drive since I did the TPS. My wife still claims it'* better, but I need to prove it for myself.

Been too dang busy to get out in the nasty cold weather to go for a test drive...

It definitely helped. I didn't drive it but maybe ten minutes, but I hit a few inclines along the way. Definitely a way to 'hide' the problem lol.

I adjusted my idle screw like the guide suggested, and that resulting in like idling at 3500 rpm. So... I knocked the idle screw back down to .52v and that made it perfect. I think at WOT, it'* at 4.32v I'm kind of thinking that it'* going to move around a bit until I get the proper screws that don't require needle nose pliers.

Sorry it'* taken me so long to get back to this. I finally had the chance to drive the car due to my wife having other problems with it (see my latest new thread) and it seemed to be 100% better! I drove in the city for about 10-12 miles and got up to speed so that the torque converter would lock up, then ease into the gas, but not enough for a downshift. Each time I did that (probably a dozen) I did not get any of the surging.

So, for now, it seems that a new TPS has corrected my issue! If the issue resurfaces I'll resurect this thread.
