hi. i'm kind of new here, and was wondering if anyone knew what the problem with my car is.

i have an '86 240, with an automatic transmission. recently, the gas pedal has become unbelievably easy to push. almost effortlessly. i cant seem to get down as far as i used to be able to however. also, i've been having problems with it shifting. it doesnt shift until about 4500-5000 rpms, no matter what position the throttle is in. if i slam it, it of course revs fast and shifts, but at half throttle, it revs slowly until 4500 rpm, then shifts.

tonight i was driving around, and put in a quart of transmission fluid. while i was under the hood, i noticed that the throttle cable seemed to be hanging out of its rubber hose. this was the lower throttle cable, the one that actually moves. when the engine is revved, it comes out fine and dandy, but it doesn't slide back into it's hose. after driving it with the cable pushed back in, the gas pedal was normal. but since it doesn't go back in, the gas pedal is back to nothingness, and it won't shift again.

so, my questions for you guys are these:
what is the problem, why is it happenning, and how can i fix it. also, how much will it cost, and can i do it myself.

oh, one more thing. my car idles at about 800-900 rpm. is that normal?

thanks a lot

chris

I know next to nothing about auto transmissions, but that sounds like a problem with the kickdown cable (the lower of the two cables at the throttle wheel). Try lubricating the throttle and kickdown cables to see if it helps. Here are some topics from the Brickboard archives that might be of use:

See this post which includes the quote below:

Throttle cable sticking would cause high throttle pressure and would cause delayed upshift. Broken cable causes early upshifts with no downshifts at speed but with all gears working. -Abe Crombie
Good luck.

As far as your idle goes, Im pretty sure that that is about correct. I read somewhere that for the B230F engine the idle speed is around 750 rpm. So thats about right. Good luck on the throttle cable though.
