I bought my 01 Trooper about a year ago. Was crashed in the front-
replaced radiator and body parts and have been driving it fine for about 6
months.

About a month ago, it started to occasionally slip out of gear on hard
acceleration, esp. around corners and progressively got worse, such that
even mild acceleration would make it happen. Then finally recently it just
wouldn't go up a hill in any forward gears. Reverse worked fine, so I
reversed up the hill to my house and parked it.

I found the trans to be low on fluid and have added in about 4 quarts of
Dexron III, - now forward gears will slowly engage with a mild clunk, but
the slightest press of accelerator makes it pop into neutral. If I put it into
4wd it will crawl forward at idle, but shudders bad if you try to give it any
gas. Reverse still works great.

I've read about the 1-2 accumulator valve and others have mentioned
'solenoids' (same as accumulator valves?)- any ideas out there?

Would a code reader give me any info? Thanks in advance-

look at the side of the trans and see line the accumulator cover on the trans is leaking. if so fix this and make sure you fill the trans up correctly

Thanks MASTERTECH- I did check the line and it does not appear to be
leaking. I did accidentally discover something interesting recently
though- I hit the ''WINTER'' button and heard a clunk in the front
differential (I assume), and suddenly the car would drive through all gears
just fine. I added in fresh fluid just prior to this. So- what do you think it
means that reverse works normally and forward gears will slowly engage
with high revving if pointed downhill (then once you get some speed built
up, it shifts through the higher gears just fine until you stop.), and all
gears will shift fine without slipping with the WINTER button engaged.

Does this point us to anything more specific? Thanks for the help!

Still hoping for an idea as to why my trans slips in all forward gears unless
the winter mode button is pressed- then it drives fine. Any ideas on what
that might mean? Thanks-
