sloppy kick down, sort of? (1 Viewer)

[lurker]

When I slow to about 10 mph to make a corner, and rapidly accelerate (>1/3 throttle) my transmission fails to fully engage. It feels as if it not engaging until about an extra 800 RPMs is added then it's OK. During normal driving conditions (>10 MPH) I never notice this gremlin.

I've looked at the kick down cable and it has a little red insert which should only be protruding about 1mm (so I've read) but the cable has a lot of lateral slop in it (3/8") at the 1mm measurement. I've tried to drive around with the slop and it doesn't seem to hurt the condition, but doesn't improve the issue either. If I tighten the cable to the point where there's about 1/8" of slop the little red insert protrudes about 1/4" of an inch, but it doesn’t improve the kick down issue. If I tighten the booger any more then the transmission will down shift too soon.

Next on the agenda is the IAC which I added the 2 oil ring solution. When I installed the unit back on the TB I marked both mating positions, but it didn't help with this kick down solution, but I'd like to add that in my case it doesn’t seem to mind where I adjust it, it almost doesn't have any effect on anything.

Now that I've beaten around the bush a few times; am I even on the right track in solving my kick down problem? Is it even a kick down problem or an internal transmission problem?

We need a Help smiley also!

I seem to have a similar problem. I am not entirely happy with the shifting of my transmission, and when I tried to adjust the throttle cable it developed slop just as you have indicated though perhaps rather more. Is it meant to have slop in it, or is there some other way to take this out by adjustment on the throttle body perhaps (1994 4.2 TD)?

Somebody, anybody?

Mine still sorta does that, but, it's been about 80K ,iles since I found that the throttle cable was not in the mount. It was floating freely and I had really weird shifting problems until I found that. PO issues.

You might wanna try a search on this forum using the word flaring. That is the term that Slee I believe uses for the symptoms you have.

Not uncommon BTW. Good luck.

I think ???? the flaring issue is when your driving up and down hills and when it down shifts from say 4th to 3rd the RPM's jump from say 2400 to 3100 RPM but creap back down to 3000 RPM's, the flare would be the 100 RPM's.

In my case this new problem feels almost as if I'm coasting under 10 MPH while in first and if I apply a little too much throttle it revs freely for about 300 RMP then catches, but again only in first grear under 10 MPH, never above 10 MPH (in first) or any other gear. So I assume that clutch plates are not bad/slipping?

lurker, have you tried this?

Hey!

Thanks for the link!

Good link medtro. I have been told in a past thread related to the same topic that the A442 doesn't kick down into gear as some would like. It is normal according to extreme trans in Australia.

According to the link, adjusting for a little slop is OK and then Play with the TPS.

Well I finally figured this bugger out.

It's the TPS adjustment.

I tried to follow the haynes manual but that was a waste of time.

So I checked the ohms at the TB closed position (580 ohms) and blindly turned the TPS counter clockwise about 2mm remeasured at 680 ohms and it's not perfect but much, much better.

Thanks for the links and support.
