Did you bother to check the transmission fluid level when this started to
happen? If not, and it's low enough to cause this much slipping, I'd guess
there's a good chance you killed the tranny by continuing to drive it this
way.

The power gain was your imagination (or your having replaced a dirty stock
filter with a clean cone), aided and abetted by your ears hearing the
intake roar.

Sounds like bigtime transmission slippage. Checked your transmission
fluid...lately? Do so now. What's it smell like?

Probably not causing your problem, but also not something to just shrug
and say "Whatever..." about. Those hoses are there for a reason. Fix 'em!

The computer has no ratios.

I had a very very similar problem (although not caused by any mechanical
changes). I thought my tranny was a goner. Turns out it was the TPS
sensor. Simple to fix. I'd recommend you try this first, before looking at
the tranny.

4th gear and 5k rpm and 20 mph?
You have serious tranny problems.

Re: Help! Jeep Cherokee can't go over 20mph!!!
'88 was still amc.. too bad.
If it was chrysler you could scan the computer very easily for codes, which
would tell you whether it's the TPS or not.
AMC is probably scannable... check out www.batauto.com and find the trouble
code section.

No the 88 isnt really scannable. I dont think you can even find a daignostic
tool for the port on that thing.
