[thabadguy]

ok i bought my 89 rs v6 auto like to months ago dude didnt tell me it had probs but didnt matter cuz i really just wanted the shell. ne ways the tranny ended up being alllllll messed up. so i went and bought another one and put it in. now it seems like its not all there. sometimes it pulls real hard and sometimes it slower than syrup in thhe freezer. wuts wrong

I don't quite understand your explanation of the problem here, please be a little more specific with less text message analogies.

You're sure everything engine wise in order? Oftern times, wheat feels like a trany problem is more of a engine performance issue.

[thabadguy]

well i fixed the check engine light. see when i floor it, sometimes it hauls azz, and sometimes it bearly goes anywhere.

That's not detailed enough info to get a diagnosis of any sort. Please explain

Any rattling from under the vehicle in the exhaust system? BAses on thsi decription, and your overheating issue, could be looking at a colapsing catalytic converter.

[thabadguy]

no not really but i hit a really big manhole and it pinched the exhaust tube a lil, and i also have and exhaust leak. and i talked to some people and the said that could it is this true

Sounds like the previous owner neglected a lot of things.....
When you put the new transmission in, did you flush out the trans cooler and lines? Whats the fluid look/smell like in it now?
When you say sometimes it hauls and sometimes its slow, does engine temp make a difference? Like the longer you drive the worse it gets or what?

[thabadguy]

no i didnt. the fluid is nice and reddish and smells good but ya as i drive down the freeway, sometimes its "cuts out"(sluggish feeling). but the temp doesnt change nething.

I'm not sure about v6's...what injection does it have, multi-port or throttle body injection?

[89IROC&RS]

sounds like it might be going into limp home mode.... have you run the car for codes..... oh wait you said you fixed the check engine light... did it just go out? what was causing it?

also you can have error codes without a check engine light. so id scan for them just in case.

[thabadguy]

it has multi port injection. i jumped the codes and it gave me a lean/rich air/fuel mixture. so i changed the o2 senser. light went off.
