Our Trooper had the transmission replaced at 33K miles. It now has 80K and has begun to shift erratically when under strain, like going up a steep hill. It feels like to me that the lock-up converter if it has one is disengaging and reengaging. It happens quickly and rarely long enough to see the rpm's jump up and then right back down? Any help would be appreciated. Also, this problem just suddenly appear, wasn't happening one day started the next?

ok what engine is there,? gas or diesel, ill guess, gas.
that symptoms Gob smacks me as, timing errors.
is the cam belt ignore for 6 years. (6x 10k per year, is 60k mile)
that is all part of a tuneup, or doing necessary service on the engine.
the belt slipped,
if you had check spark timing ,it be way off, and that belt caused that.
gen 2, trooper have this line up, 3.2 L 6VD1 SOHC V6
3.2 L 6VD1 DOHC V6
3.5 L 6VE1 DOHC V6
3.0 L 4JX1 TD I4
3.1 L 4JG2 TD I4
i ask every time, and not one ever can figure out whats under the hood. sadly.
the last 2 are diesel...
if you disclose engine that tells the spert, what EFI system is there.
cold slips. can be, clogged filter.
cold AFT will not flow well in any clogged filter.
if lucky this can be it.
do not let it slip or the clutch packs burn to a crisp fast !
get a full flush and filter. and cross fingers.
ill assume the ATF levels is no low or too high. right>
do not guess at method or guess AFT types. ask. or read the operators guide, in the glove box. if not lost, if lost buy one?
The transmission doesn't have a dip stick you will have to take some where and have them check it, unless you feel comfortable doing it your self. The power steering on the other hand. If you pop the hood look around you should see a black cap that says powersteering fluid, when you take the cap off it should have a dip stick attached to the lid if not there will be a fluid level mark on the side of the tank, which you took the lid off of.
Ya sounds like the electric shift solenoid. Problem with electrical. Will not give you a warning. Will go bad in a heartbeat. You can try unhooking plug that gos into the trans and spray electrical cleaner on it. plug back in. Wiggle some wires and maybe find one loose or broken wire or connection and hope for the best. But its probably the tranny with that many miles. Go to Advance Auto Parts they usually scan your car for free for codes. Good luck
