THE PCM MODULE.
no country stated, the 728ad shows Europe. (why?)
"I found"

where, at ebay, at pick-apart, or ?
USA cars have 11 PCM for one engine. fact.
and 100s more world wide.
what a question, just a p/n
then you post to grand Cherokee and then text leaving out Grand.?
why?
i searched the part at jeep and is wrangle part, 629ad.

you do know that it must be reprogrammed to your car right:?
the pcms on cars can vary
by engine, trans opted , 4wd/2wd,and year.
federal PCM
Calif PCM
and mexico PCM
and 9 more. just for 1999

is yours 42RE for 45RFE?? tranny??? 30/32 RH? what?
post county (or state if calif)
post engine and year
post body and not contradict.?
post drive line, in car, tranny and if 4wd?
then we can match it up
or call jeep.com

they (jeep) will do this magical thing!
ask you the VIN.
and then look it up in their database.
and see ALL THE ABOVE even what radio is in it. of 5.
me, im a glass half full guy (hard knocks, reality stuff)
id not even believe the part in car is correct.
im too SAVVY !
i find out from jeep what it should have first.

not one matches the 4.0L in the GC.

(part not found, is this a non usa part?) im stumped

was fun to try.
but im stumped.

why? got DTC errors? please post them. just curious , me too.
5speed stick, there is no such transmission here. ok JK08 ,usa.
4wd?

mine is 6 speed stick, the 5speed option is the automatic.
6sp is DEH trans.or NSG 370
with NV241 transfer case.
my wild guess is its really a 6 speed manual, with 4wd.
am I correct>?
and is USA, not an Export.
my fsm does not cover, 6 speed VSS, oops.
i wonder if the VSS on the 6peed, uses speed from the ABS.
the automatic vss is on the left side of the tranny case. and input speed and engine rpm speed. but that is A/T.

M/T as your post clearly states is another matter.
the parts list for the 370 box shows no sensors at all ,just 1 reverse switch, then i look at the car 241 transfer case then the parts list.
it too , dont have a sensor. only , 4wd switch and is not a speed sensor.
so that leaves 3 more,
front axle, no.
rear axle ,no (only a lock up switch option)
leaving what, ABS.
must be the genius at JEEP said, one day, well gee abs knows speed, why not just get that for free on all 4speeds.

the A/T needs the sensors to shift right, but not any manual ever.

The electric drawings for jeep jk08 show no speed sensors at all on the M/T. (dedicated to forward speed via the transmission side)

see here a nice JK08 full parts list in PDF.

does dont move mean it slips

can you move throttle to say 3000 rpm and car will not move.

this is gross slip. or FLare. RPM matters. here.

why?, because the engine must be good, to move forward.



hot and cold engine? no move forward.? or both?

standard means manual transmission.

so the clutch is bad.

my guess is you meant it has a A/T box.

mine has a 6sp, M/T box.

apples and oranges diffr.

this car had 4 transmission options day1 factory build day.

4.

2 auto

2 manual standard, stick.

ill guess at 32RH at (not AW-4 auto) 32RH is a 3 speed.

hydramatic.

levels good, per the operators guide, do not guess, use the steps in the guide, the A/T box is not checked like the engine, at all.

is the fluid, pink (ATF) or black and with metal flakes, dripping off end of dip stick. or stinks, smoky not sweet smell.

???????

is the shifter moving the shift side crank on tranny correctly?

this takes careful observation .

1. level checks, and lever action.



2. replace the filter now. was this step skipped for 22 years?



3. get the full flush no , may be the AFT fuild types were mixed up?



4. this means the stall test fails, (dont move)



5. so in the FSM the next test is the pump pressure test port test. called LINE checks, this is next. if fail the tranny is bad.



6. whats next depends on %5

the tranny pages below, pdf page 71 shows the 1st line test.

there are 5 line tests.

if you can do that, , then find a shop that can.

you will never get to the stall test because the tranny slips. test 6



see yJ 93, tranny

thrust bearings are bad and the flywheel is moving out of range of the crankshaft sensor, or the crankshaft sensor is sitting too close to the flywheel.

Have you checked the clutch master cylinder fluid level?

if this is a 5 speed manual transmission...all you need to do before putting your jeep into reverese is puting it into first gear and then shifting it to reverse to avoid any grinding or problems shifting into reverse...this isn't a problem just a poor jeep design by not installing an extra gear to eliminate this grinding or shifting problem

Sounds like you may have bent a shift fork or your cluster gear has some missing teeth on it now. I would venture to say that is it a bent shift fork. This will require the transmission be removed to gain access to inspect and repair.

shift tranny from 1st-3rd if engine revs up clutch needs replacing

use two nuts tightent them together put wrench on back nut and spin off against front nut
