Acceleration Problem...transmission?

[Noelle]

My '89 2.3 4 cylinder is having a lot of trouble accelerating from a standstill or lower gears. I can slam down the pedal and still be plodding along at 5 mph, gradually and slowly making it to speed limit. Merging is a nightmare. For some reason, the problem is off and on. After I changed transmission fluid, it went great for about 20 or 30 minutes, and then went back to how it was. I've tried both slowly pushing the pedal down and slamming the pedal down to the floor. Still goes extremely slow either way. It seems like it's having the most trouble changing from 1st to 2nd gear. Also, the car jolts when I switch from Park to Reverse or Drive. I'm not sure if they are related problems... Any ideas on what could be wrong?

I have similar problems. I was also having problem with my overdrive gear not engaging. I am currently replacing my TPS and soon my IAC. If the IAC doesn't work I'm taking it to a mechanic because I'm frickin tired of it. Post more if you find anything out.

Hey,

Is the check engine light on? if so, what are the codes?

When was the last time you did a tune up? whats the timing at? how much fuel pressure do you have at idle? codes? bad EGR? etc start with the basics

If you have changed the fluid did you change the filter too? i would try that. It sounds like maybe the torque converter is going bad, or maybe the bands in the tranny. I would start with the easy stuff and then move to digging into the tranny.
