Hey guys. So two years ago I went with my brother in law to buy his first cherokee. turns out he really didn't care about it and a week after he got it, it died on the highway.

Finally after two years of sitting, this morning I was able to fix it (after buying it off him for $600). Turns out it was the ignition coil. Its starting and driving fine except the transmission is slipping like a ****. Tomorrow I plan on getting it flushed and filled with new fluid.

Any chance the transmission got screwed just by sitting for that long? What should I do?

Check the fluid level.
If it ran fine before I am sure thats it

Btw you ****in scored!

YEAH man he paid about $5000 for it. I pretty much stole it. The dipstick shows full.

Transmission probably isn't the only issue. It's hard to believe someone would spend 5k on a vehicle to drive for 1 week, just to park it over an ignition coil. YMMV

Exactly how is it 'slipping'? What a lot of folks describe as slippage is often something else, like starting off in high gear, etc.

If you have the fluid changed make sure they use Dexron III, Not ATF +4.

How is it idling/running otherwise?
Like stated, get fluid change check/change first. In fact, if its been sitting for two years unused, you might wanna redo most fluids actually. Re-adjust throttle linkage. If its been left unused for two years and the above isnt solving the issue, I'd def look at the TPS, since its closely involved inn shifting issues.
I'd reckon that the solenoids would be able to cope with being unused for two years...

Try driving it by using the shifter in 1-2 and shifting manually.
Quit slipping?

If so, check out the fuse for the Trans Control Unit under the passenger side dash.

Cruiser, just curious here. This is a good way to make a possible distinction between the electric and mechanical part of things. If it would not fix the slipping, what would you think/check next (assuming fluid is all nice/level good and the trans has not too many miles on it) ? Solenoids? Curious since currently reading up on transmissions, since they have always been something I'd stay away from...

believe me, he parked it over a coil. he's not a car/jeep guy. it idles nicely at 7-800. sometimes it won't shift without me manipulating the throttle, then sometimes after 2000 it will just shoot past 3000 with no movement.

Do you have a CEL?

If it was a solenoid you would more than likely be getting one.

A code? I get 12, then 55, which is just "the battery has been disconnected before 50 cycles." UGGGHHHHH i found an empty bottle of ATF 4 in the back!

Test/Check your TPS. Preferable with a non-digital multimeter do give you a good visual if there are any dead spots in the sweep from closed to full open throttle. Good chance you will find a deadspot in yours.
The TPS is closely involved in transmission shifting characteristics.

I would check to see if that is indeed what they put in there.
You really want Dex III (or best Dex/Merc III)
