2004 grand cherokee transfer case problems by chateaub
Nov 16, 2008 (7:55 am)

My 2004 has become a nightmare to disengage part time 4wd (4 wheel hi). It is the select trac package with the 4.0 litter. Sometimes it takes a 1/2 mile or more of constantly pulsating the gas pedal to finally come out. I have tried backing up when this happens and sometimes it works and sometimes it does not. If you have to park and restart it will disengage with a fairly large bang. It does this especially on turns. I only shift with the vehicle moving with my foot off the gas, as I was told by the dealer that this is prefered.
I am guessing this happens when the front axle is binding a little from being on dry pavement when the transfer case finally decides to disengage. When the vehicle was newer it did this once or twice, now it is constant. I have had the case and axle fluids changed at the proper maintenance schedule using factory fluids.
It has 63k on it and is still in warranty. I am bringing it to the dealer this week and was hoping for any advise from other owners with similar problems so I know how to respond if the dealer tries to give me a song and dance. Any help would be greatly appreciated.

does your-04 have a vacm module on the front axle? check and clean the works on that,as that's how my -90 pioneer worked,and was told that's a standard axle for the cherokee..not shure if grand has that diffrent of a system,but would be worth looking at..maybee a weak or broken release spring,or a bad vacum diaphram or what have you..but it's gotta be there,as that's where the front axle is turned on and off..good luck!

hopefully its either the oil pressure sensor in the block,or -less likely,the instrument cluster..might just be a wire came off,as the pressure switch wire is right next to the oil filter,and could've gotten unplugged..check around the filter for a unplugged wire..otherwise,you have no oil pressure,and have,or will soon blow up the motor..(just kidding--i hope!)..no "ratteling" noise outta the motor?,like it's still got pressure?..otherwise,worst case senario,put a "old school" mecanical pressure gauge in it.

Hi,
 
  I know this is an old post, but I have the same problem! Works ok in 4 Lo, but no traction/engagement at front wheels in full time 4 Hi with Quadra Trac II. Anyone know of the fix for this?? Thanks!

Thanks for the info. I will check with my local mechanic about the vac module.
I want to make sure the dealer will warrentee as part of the drivetrain. I have talked to jeep service guy who owns the same truck. He said that sometimes his does not disengage right away so he stops and backs up and it comes right out. Mine does only sometimes no matter how far I back up.

I used to manage a transmission shop,in fact bought a 94 JGC for $1.00 when the owner decided she did not want to put the 2500 in a rebuilt transsmisson.Just sold it and bought a 04 JGCL with 31k on it and will probably buy the 7/70000 Powertrain if it looks better for Chy suvival.
 
Now your trans, have they dropped the pan? Whats it look/smell like?If it has metal and smells burnt then pull the unit and have it rebuilt.
Not sure how many miles but a 95 with anything over 70,000 is going to need a master rebuild kit and not just gaskets and seals.
 
You may have misunderstood the "new" transmission quote,there is no one that I am aware of that sells a "new" or fact reman unit for that.A good rebuild is over 2K,factory rebuild or a Japser is a bit more.For 1300 that might be a used unit,what is warranty on it?

97 JGC V8-Internal Transmission Failure? by klsflyer
Nov 22, 2008 (1:20 pm)
Reply
Check engine light on and very sluggish when accelerating. Having to push accelerator more than usual after stopping. Wouldn't you know on a weekend and my mechanic is closed. Fault sensor code (AutoZone) came up with P1763: Governor pressure sensor too high. Causes: 1)Internal transmission failure 2)Open or shorted circuit condition. Any ideas? Safe to drive? No misses or noises from the engine. Smooth gear transitioning. Start and idle with no signs/sounds of any problem. Biggest change is it takes more accelerator pressure than normal to get moving.

TRY this----engine off---key in ignition--trans in neutral.
Place foot on brake, hold it--at the same time turn key in this manner--on-off,on-off,on.
Sometimes this will clear codes and problems.
 
If this does not work---disconnect the negative batt cable and let it sit for ten min. Usually this will clear any codes and bring everything back to normal.
 
The key trick clears my ck eingine light problems.
Good luck
