Sometimes my Car surges when light throttle

[99GPGTP]

sometimes my car surges when im at light throttle or when cruise in on at 45-60mph and i start up a hill and the car accelerates on its own. im not getting any codes in the transmission or ecm. i have done a trans mission flush about 2k miles ago. the car has 150800 miles on it.

im wondering if its the torque converter going bad. or if i might be able to put a tcc solenoid in it and fix the problem. i am gonna put a zzp a shift kit in and new filter in a couple weeks.

any ideas please let me know

My car has done pretty much the same thing since I got it last year. I've done a fair amount of reading but I haven't made any attempts to fix it because I just don't have the cash.

I've just learned to live with it by punching the throttle a little harder to make it downshift when I go up a hill. I also hold it back to 2nd and 3rd in the city.

I would replace the EPC (pressure control) solenoid as well as the TCC solenoid.

i have found my self downshifting a couple times. im thinking of replacing the solenoids and filter kit along with a shift kit at the same time. i just hope it fixes it and i dont need a torque converter

let completely off the gas to let the torque converter unlock, then ease back into it.

it did it to me today on the way to work at 30 mph. i had to tap the gas to get it to stop
