99 Jeep grand Cherokee Gearbox issue help
Discussion
Hello all
Just picked up a nice clean 99 Grand Cherokee 4.7l V8 on LPG which apart from sloppy steering seems to be looked after and in good condition. However I have a slight concern that's its not getting out of second gear , it seems to drive fine and doesn't sound like it struggles but I notice it change from 1st to second but then nothing its revving at around 2500rpm at 60mph . Should I notice it changing to 3rd , 4th etc im really not sure of how to test this or find out . Just got than sinking feeling

The V8 box is different to the 4L. Could be a variety of faults & I assume it has no Engine management light on?
Needs the codes read really, so good skills on the V8 box on the WJ Jeep facebook group. I assume level is good? ALso probably needs a filter & fluid change, scheduled at 90K.
Would recommend Terry Cloke at A1 Chrysler in Higham Kent if not too far. WOrth a ring anyway. 00447437583783

thanks for replys
manually set to 1 and then moving it up to 2 and its not changing gear , if I then select drive it seems to shift up possibly to 3rd and then stays in 3rd. Im not convinced 2nd gear is there at all with no difference between 1 and 2 .
Loads of fault codes showing but no light on dash so they maybe old codes that need clearing so I plan to disconnect battery to try and clear them because there are no real issues when driving it apart from the above.

i believe these relate to the following
P0523
Oil Pressure Sensor High
Oil pressure sensor input above acceptable voltage
P0700 (M)
Check Transmission DTC's
This code indicates that the EATX (Transmission controller) has an active fault and has illuminated the MIL via a BUS message. The specific fault must be acquired from the EATX via a DRBIII tool. (Input or Output Speed Sensor failures often cause this code and are a common failure part on WJ Grand Cherokees).
P0201 (M)
Injector # 1 Control Circuit
An open or shorted condition detected in control circuit for Injector # 1 or the INJ 1 injector bank.
P0203 (M)
Injector # 3 Control Circuit
An open or shorted condition detected in control circuit for Injector # 3 or the INJ 3 injector bank.
P0205 (M)
Injector # 5 Control Circuit
Injector # 5 output driver stage does not respond properly to the control signal.
P0206 (M)
Injector # 6 Control Circuit
Injector # 6 output driver stage does not respond properly to the control signal.
properly to the control signal.
P0208 (M)
Injector # 8 Control Circuit
Injector # 8 output driver stage does not respond properly to the control signal.

thanks bit to far for me, and im really not got a clue on mechanics lol , but I assume you mean to check transmission fluid level if I can work out which one it is?Needs the codes read really, so good skills on the V8 box on the WJ Jeep facebook group.

Worth doing a full reset by disconnecting the battery, will need radio code reset after. But realy needs someone with a DRB reader to reset them all & reread them.
ive reset the codes and the following has come back up, I did check the engine oil and transmission one and they looked ok , but ill do it again after a run

manual says to use ATF+3 or ATF+3 type 7176 is that the same thing?
Nope now out of date, this is your bible for these sort of things & the FB WJ group. http://www.wjjeeps.com/service/maintenance_wj.htm#...
There are two areas for 0700 faults one is the gearbox solenoids & sensors around $150 from the US & a pan drop, filter change & new fluid. Or there is a switch module under the lever that can do this. This is specific to V8 & the guys on FB have been having issues with these recently. These codes WILL need scanning properly so you need to find someone locally with a DRB.

OK so it's ATF+4® I need, you got a link to what I need? I'll see if my local garage can read the codes for me properly tomorrow morning.
Opie list a few but something like this. Edited by djcla on Friday 19th August 19:53
