Re: 97 JGC V8-Internal Transmission Failure? [klsflyer] by trickster

I hope you got your tranny fixed, but if not then.....
I cannot see internal transmission failure, because you state that in fact there is smooth gear transitioning. I assume that other than using more fuel to get you where you want to go everything else is fine regarding the transmission. There is a governor sensor located inside the transmission pan, and that needs to be changed. I would have a compentent shop or dealership do the work, (it really is messy work), and since your at the point, changing your transmission filter is a very good idea (about $30 ). A good idea for the first 2 weeks after the fix, is to put cardboard on the ground under the transmission. Or just keep an eye on it. Transmission pans have a tendency to leak from the bolts loosening off, and will need to be re-torqued to spec, unless you ask them to use lock-tite on the bolts.
 
I hope this helps you, and good luck m8.

if your fan works with the air on and your problem is no heat then it is the flaps in the blower housing that are not directing hot air into the cabin. had the same problem and i went to this forum and was directed to a company called heater treater. they sell a product that is specifically made for this problem. was easy to do and only took 45 min and cost $145 heater has been working great since, it comes with full idiot proof instructions, hope this helps.

Start engine--run til hot--feel the two heater hoses near where the enter the firewall connections. If both are equally hot the water is circulating thru the heater core.
Kill engine.Drop the golve box lid all the way down. You will need to release the rubber stops and flex the two pins on the top of the lid so that it will come all the way down.
At the left side you will see a squarish black box attached to the blower housing.Remove the two srews holding it. Lift the housing away from the blower house(leave wireing connected). Pay attention to the shaft alignment. Turn the switch on. Set air to floor. Manipulate the heat control. If the shaft ring does not move within the motor housing do this. remove the 4 screws on the housing. Slowly lift the side off to expose the gears. Remove the three regular gears to expose the worm gear.Again manupilate the heat control. If the worm gear does not move.---Remove the tiny motor and turn the screw by hand to free it up. Again see if the motor will run. If it runs--- replace everthing. Reattach the motor housing to the blower housing and try it out again. That fixed my problem at no cost--just time and frustration Good luck--Smokey Swann---Tx

Stalled out by joesjeeps

I have a 1995 Grand Cherokee w/ EFI, 5.2, quadratrac.
I drove it approximately 30 miles today and it ran fine but when I took a lefthand turn three blocks from my house it just died. I tried to start it and I get the starter turning but it won't turn over.
I thought it might be the fuel filter so I let it sit for about an hour thinking that if it was clogged the sediment might settle but got the same result.
Any suggestions?

Did the engine turn over? Was voltage near 12 with the key on? If the engine turned with the starter but the volts were below about 10, you may not be getting ignition, and fuel might also be a factor if voltage is low. Sorry I can't tell you for sure what to poke at.
 
Anyway, at least you were close to home. Merry Christmas.

2001 Grand Cherokee, locking wheels..... by cesarherna
Dec 26, 2008 (8:35 am)

Hello, I am trying to install a different bolt pattern rims to my Jeep, so I get a set of wheel adapters on the internet, but the wheels get lock with the adapters on it and is impossible to move any wheel by hand and not even trying driving the car, the size on the adapters are fine, everything fit perfectly and I don't see any reason to what is happening. Is any wheel sensor locking the brake system?
Has anybody seen this before or any possible suggestion?
 
Thank you

Ouch. I'd say, start by making sure you have good batt connections. Then, it's probably the starter and/or solenoid for the starter that's sapping your batt. If you've tried to jump the Jeep unsuccessfully, I'd put money on the starter assembly. If it jumped OK, I'd sat batt cables are a guilty party.

Coolong fan woes- overheating by hittin1
Dec 27, 2008 (3:45 pm)

I am the proud owned of a 1999 Jeep Grand Cherokee Laredo 4x4 4.0L.
 
Two days ago after cutting my jeep off I noticed the fan running.. I know it is normal but it remained on after 1 hour.. So i unplugged it by the radiator.. 45 mins. or so later i plugged it back in to see if it would still be on and it stayed off. On the drive home I noticed that I was starting to overheat at idle.. Checked when temp was high and fan was not on..
 
Changed Coolant temp sensor
checked fuses.
cant locate fan relay..
a/c works and fan doesn't come on
fan is working when I jumped it to battery.
 
Can anyone help diagnose this problem.. Please.
 
I have a 260 amp alt- 3 batts, and 6000 watts on 2-18's This is a daily driver and Competition vehicle. I do not want to overheat and ruin the motor. (not a fan of the 4.0L but it is what I have)
I do all the wiring on my Car Audio and have decent knowledge of 12volt systems.. I was a mechanic years ago but changed jobs due to eye injury.. So I have some knowledge of automotive trouble shooting and diagnostics. II need advise from someone who knows this specific vehicle.. Any help would be appreciated.
 
If anyone has questions about car audio/jeeps i would be glad to assist as well.

Sounds like the fan controller module is dead. One of our Jeeps has done the same thing. As a fast fix, we rigged the fan to be on when the lights are on. This fix may also work for you as well, but it is a temporary fix.
