Your problem can be caused by a few different items. Throttle pressure may be low, but this generally happens when it has not been adjusted properly after a rebuild or engine work has been done unless a control cable has broken. Next is the map sensor that has some influence over the electronic shift control. after that is the control itself. If the fluid you changed was not burned or contaminated with either clutch material or fine metal, I believe you will find your problem in one of the items I mentioned. Or, possibly your speed sensor.
One caution though. Don't run your engine up to 5K too often or you will find a connecting rod hanging out of the block very ain't a smallblock chevy!!! Do some good testing or bring it to a relaible transmission shop asap!

My 2002 jeep grand cherokee won`t change out of first gear I can only drive under 25 mph?

check fuses.
then scan it.
the scan tool will in fact tell you what the trans is stuck
The PCM shifts the gears, so if it cant, it complains big time.
those are called DTC errors.
all shops in town can scan, or you can buy one and DIY.
on all modern cars. 96+

at 25mph 2nd should happen.
if not, the trans will log, DTC errors. for it.
but it's best to scan and see all errors.
there are are other issues, limphome on engine and transmission.
but the DTC errors show that too.

Auto transmission won`t change out of first gear

posted now 3 times this post is longest so will answer here.
not 3 times. ever.
so like all cars like this, with electrically shifted box.
you check fuses first.
then scan it.
if the TCM sees errors (scan it) then it tell you it has errors.
and will either not up shift, or will go to limphome mode.
no matter, the reason you dont know is you didnt scan it first.
the tool is cheap as $10. too.
all modern OBD2 tools work, buy one rent one, barrow one, etc.

Have a '93 Jeep Grand Cherokee, 4WD, 5.2L, 8 cyl, automatic that's not shifting. Transmission fluid looks good, no burnt smell, no metal bits in fluid, no grinding gears. Won't shift til you...

If the transmission will not go into gear or has trouble finding gears and has the proper amount of fluid, the shifting linkage could be bent or misaligned, especially on automatic models. The linkage can be found on the driver side of the transmission, toward the top of the unit. Inspect it to make sure the components aren't bent or broken and have someone shift the Grand Cherokee while you watch from underneath. Most times, only minor adjustments are necessary.
Also, check Torque Converter and scanned the TCM (Trans Control Module) to know if some fault code is stored there.

How to shift from 2wheel drive to any of the 4 wheel drive modes thank you

if I'm not mistaken, it has the shifter for the 4wd just to the left of the gear shift? In that case, the best way it to stop, put the gear shift in Neutral, then place the 4wd selector in your mode of choice.

Auto gear problem

You will want to check your transmission governor transducer on your transmission, and if you have to replace that...after you begin to drive it the computer system programs the shifting for you. It takes a couple days to get back to normal shifting. Run diagnostic testing on the transmission first, and see if you get a communications failure.
