RPM drop at WOT? automatic 2g non turbo

[ECLIPSE95]

so when im crusing down the road around 60mph or so about 2.5k rpm and I punch it, then the rpm ramps to around 4-5k but the needle will drop about 100-300rpm and jump back up again and resume climbing. like a slipping clutch. I keep the car at WOT, but the car has a hard time gaining speed? The car used to have some power, but its been getting really bad lately. suggestions??

anyone? could this be a possible torque converter issue?

Maybe a TC but I doubt it have you check the tranny fluid and/or drained ot lately? BTW nice talon im trying to find a white 2g as a DD.

Yea, I got the fluid changed and its all up to par, but I still have the problem.

Hmm it almost sounds like its in 2nd gear. I think its hard to say have you priced a tranny diagnostic at a local tranny shop? That might be your best bet as it could be the TC or the TCM and maybe the wrong tranny fluid. I would just check for leaks or maybe try some LUCAS tranny slip-stop see if that helps it any.
