Slipping Transmission badly

[kjred4wd2004]

Went camping to Ocotillo Wells and started to slipping really bad drove it for like 30miles and it just got worse. Need ideas or should I sell?

Check the oil level ASAP, only use ATF4+ to refill

How many miles on your 2004 KJ?
Does the ATF+4 transmission fluid on dipstick smell burnt at all?

Drop ****** pan, empty, replace filter and gasket(AMAZON).
Get 3 bottles Lucas Transmission Fix 24 OZ and 2 quarts ATF+4 AMAZON)
Premix these good in something like a used 5 qt oil container.
Refill ****** and top off with ATF+4 if necessary to have fill level right.
Start driving in first and shift until slippage, stop and start over.
if you are lucky you will be able to get to 3rd and your problem will be
overdive; that may take a couple of hundred miles.
If this doesn't work you may need a couple of new solenoids and then you
make the fix/buy decision.
I fixed a 2009 45RLE this way recently and previously an ARMADA that was
throwing a 780code.
Good Luck what ever you do.

Forgot to ask if it was slipping or really shuddering. Shuddering may mean
torque converter is going out. Transmission fix mentioned may stabilize it.
Only a shop with test equipment can differentiate. If problem is in most/all
gears may point to converter locking/unlocking; very fluid driven.
