Jeep - Grandcherokee :: 2002 - Slips In Transmission

I was experiencing a slight slip in the transmission first thing in the morning when the temps were below 60 degrees in my 2002 Jeep Grand Cherokee (42RE). Per recommendations of many of the regulars on this forum to combat such an issue, I added a can of Berryman's B-12 Chemtool to the fluid. I drove it a couple times and everything seemed fine. It sat for a week or so, went to drive it tonight, and now the check engine light has come on and the transmission is slipping badly.

I don't know if they have changed anything with that stuff or what, but I just wanted to give a heads up that this may not be such a hot idea anymore, for whatever reason. I will try changing the filter and top up with some fresh ATF+4 (and probably drain and refill a few times) and hope for the best. I don't have a code reader right now, so I can't pull the codes and don't want to drive it to the auto parts store the way it is now, but am pretty sure they are related to the slip.

Jeep - Grandcherokee :: Engine Sounds Like Its Turning 4000 RPM But Only When Cold

My Jeep sounds like it is in low gear and engine sounds like its turning 4000rpm but only when cold. This is so noticeable that dogs stare and pedestrians run for cover. Once the engine and drivetrain warm up a little, all is normal. The reality is that the engine is only turning 2500rpm and it is shifting, but the tranny doesn't feel like its grabbing very well. After just a few minutes driving, all is well and there is plenty of power. Fluids are all topped off and fresh.Is it time to warm this baby up and drive it to the nearest car lot?

Jeep - Grandcherokee :: Squealing / Screeching Noise When Turning On Air Conditioner

A little over a month ago my battery died and I ended up having to get the battery installed one day and the alternator installed the very next day. After the alternator was installed, I started my car up and when I eventually turned the Air conditioner on, it started making a screeching/squealing type noise. I was first told it was the belt needed some lubrication but that didn't work.

I was later told the ac compressor was bad so I had it replaced. The mechanic thought he ordered a bad compressor so he ordered a new one and installed it....it was quiet for about 2 days but then it started squealing again. the sound was not as bad as before through but it was slowly getting worst. I took it back and he then told me the alternator was causing the problem on the ac compressor so I again I had the alternator replaced....no change. He also replaced the belt and no change. at this point we don't know what's causing it?

Jeep - Grandcherokee :: 2009 - Left Rear Noise At Highway Speeds?

I have a 2009 Jeep Grand Cherokee 4x4 Laredo. For approximately the past 7 months there has been a noise coming from the left rear of the vehicle at speeds above approximately 60 mph. The sound is not metallic in nature, it sounds more like a seat belt flapping against something. The frequency is approximately 2 Hz and is very consistent at highway speeds. The driver can seldom hear it apparently due to interior acoustics, but the someone in the passenger seat or the back seat hears it plainly, over a period of time it is very annoying.

In addition, if you touch the left rear interior side panel (in the cargo area) it seems like you can feel a small vibration that matches the sound. I have had the vehicle inspected by Jeep, they find nothing. I have had the left rear interior panel removed to see if there was a problem with the sound system cable bundle that runs through there, but it was OK. We thought it might be the metal gas tank door vibrating in the wind stream, so we taped the door down, but the sound was not affected. What the source of this sound might be?

Jeep - Grandcherokee :: 1999 - Getting Strong Odor Of Gas When Fueling Up - Does A Downshift When Making Left Turns

When I fill my tank with gas I get a very strong odor of gas throughout the vehicle, what do I need to check to fix this?

Also this one is weird, but everytime I make left turns ONLY, my Jeep does a down shift but stays in Neutral longer than it should but then kicks into gear by me taking my foot off the gas pedal and reapplying. What this could be? I have made sure that my Transmission levels were fine but I am baffled what the problem is?

Jeep - Wrangler :: 2001 Slips Into Neutral When Driving On Highway

I have a 2001 Jeep Wranger (4cl) automatic that has hated highways. When i drive on the highway, after about 4 hrs, my jeep decides to slip into neutral. So i initially have to hit the gas pedal to make it down shift and then it seems okay but of course after about an hour it does the same thing. Hence a long ride becomes much longer. I usually pull off and let it the engine cool down and that seems to work and i can resume the highway once again. I have had the transmission looked at and a transmission flush done. I have been told that i do not need a transmission but the mechanic has no idea why this occurs.

Jeep - Grandcherokee :: Auto Transmission Won't Get Out Of 1st Gear - RPMs Can't Exceed About 29 Mph

2002 grand cherokee... Just took her in on Friday to have valve cover and oil pan leaks fixed, and within an hour of picking it up today the automatic transmission won't get out of 1st gear… rpms rising and can't exceed about 29 mph. Straight 6 engine. Any chance the mechanic messed something up, like a throttle cable or something, or is this just terrible karma?

Jeep - Grandcherokee :: 2001 - Missing Slightly / Gas Going Down Very Fast

This problem started out about a month and a half ago. It started missing slightly. Then I noticed my gas was going down very fast. So I started watching it, A five mile trip used a eighth tank of gas. It keeps getting worse. My husband popped the hood and was looking to see if he could spot anything.( Couldn't smell any gas) He noticed the purge control solenoid wasn't making the noise it normally does. He took it off, cleaned it and put it back on and it started working again. ( NO CHECK ENGINE LIGHT WAS ON AT ANY TIME ) It did it again.

So we called the dealer, made an appointment, took it in, The dealer service guy said he Scanned for codes PO443 Performed Diagnosis Found EVAP PURGE SOLENOID Sticking Open. He said everything else checked out good. He ordered the part, called said it was in, went back, installed it. Amazingly IT"S STILL NOT WORKING. Now, I Do Not TRUST the dealership. It Stalls and misses and spits and sputters when it is in park and you give it the gas. There's times when I am at a parking lot waiting to get out and I start to pull out it trys to die on me.

Ford Aerostar :: 1996 - Transmission Slips - Clicking While Turning - 12 Mpg Mileage?

I just recently bought a 96 XLT 4WD Aerostar. It's got about 158,000 miles on it. It's got a few problems I wanted to ask about.

1. When I'm on the highway, once I reach about 82 or 83mph the transmission seems to slip into neutral. Does fine around the city and every other speed on the highway but once I pass 82mph it slips and revs really high. Could it be the torque converter?

2. Clicking while turning sharp and reversing while turning. I figure it probably needs new cv joints?

3. The gas mileage seems terrible. I still have my Ford Econoline 250 and that seems to be getting better gas mileage. What might cause the mpg to be as bad as 12mpg on the highway?

4. The speedometer goes nuts after about 40mph. Is that an easy fix?

Jeep - Grandcherokee :: 2001 4.0L Started Stalling When Coming Up To A Stop

I have a 2001 Grand Cherokee 4.0L with 215xxx miles. It just started stalling coming up to a stop, but then it starts right up no problem. Engine idles a little rough and the gas mileage has gone down somewhat. The CEL came on a while ago, and the auto shop checked the computer code and said it was the neutral safety switch. I brought this up with a friend who had the same problem and he rebuilt his and said it was easy. So I was going to attempt it, but I can't find the darn thing. @ questions:

1)where is it? and
2)could the NSS be causing the stalling?

Honda - Grandcherokee :: Check Engine Gas Cap Code On 2001 Jeep

My daughter's Jeep check engine light is on. Trying to get the car inspected so cannot be ignored. I think the code wasP0422, indicating it needed a new gas cap. We bought a new gas cap, cleared the code and it went away for a few days but before she could get it inspected, the light came on again. I saw similar problems suggestions were to get a better gas cap (we got one at autozone), or it could be something like a pump problem. We haven't taken to a dealer - it's a 2001

Jeep - Grandcherokee :: 2001 - Random Sound Inside The Cabin

The sound is random, inside the cabin, probably comes from in front of the driver. Lasts for a few seconds but goes on repeatedly. I found that when I apply the brakes, even a gently tap, the sound goes away, but will return.

Jeep - Grandcherokee :: 2001 - Overheating / Temp Drops When Turn On AC Or Heater

My '01 Grand Cherokee Limited is overheating. I have changed the thermostat and ran a leak test. I am not having a leak. The temp drops when I turn on the A/C or heater. I went back to the shop that changed the thermostat and leak test. They said it was the fan control and I have to go to the dealer to reflash the program for the fan control. I made the mistake of asking the dealer to reflash, instead of having them check on the overheating problem. I'm planning on going back to the dealer to have them diagnose the issue.

Jeep - Grandcherokee :: Loss Of Oil Pressure

I have a problem with my jeep grand Cherokee Laredo 5.2v8 losing oil pressure when the engine reaches normal operating temperature. the jeep sat for 2 years but we got it to run. when normal engine temperature occurs, the engine drops oil pressure and stalls. I have changed fuel pump,oil pump and oil pan gasket. also ran a cleaner through the engine. it doesn't matter if its winter or summer. the only way I can keep it running is to keep my foot on the gas pedal. if I don't do this the jeep stalls. a mechanic said it was the bearings. I don't believe this because there is no knocking noise when the engine is running. it has 103663 miles on it. it has just city and highway miles on it. never has been off road.

Jeep - Grandcherokee :: Hesitates When Going From First To Second Gear

My wife says our 2002 Grand Jeep Cherokee very rarely hesitates as it moves from first to second gear (once every week at most). I've never felt the problem, but she says its happens when from a dead stop into 2nd gear. And she said there are no other times when the vehicle hesitates (fine in every other gear). No other weird noises and the power seems fine. Its an automatic transmission and I've had the fluid and filter changed recently. What it is? Transmission? It is due for some new spark plugs... any chance it could be that?

Jeep - Grandcherokee :: No Oil Reading On Dipstick

About a year ago the oil stopped showing on the dipstick of my 95 Jeep Grand Cherokee. It is the original dipstick. I have changed the oil, filled it according to manual. It runs well, engine has no ticking (unless its low on oil, then I add a quart), pressure is fine. Just no way to check the oil !The tube is still attached from looking at the outside.

Jeep - Grandcherokee :: Shuts Off In Hot Weather

Last summer my wife's 2000 Grand Jeep Cherokee began shutting down while driving (electric stays on) on early hot days after about 40min of driving; even when the AC is off. About 10min later we can restart as before (before that it won't even crank). Over the winter the problem went away but returned again this spring/summer with the hotter weather (>80C). Its not the no battery or alternator and no one can seem to figure out the problem.

Jeep - Grandcherokee :: 1998 V8 5.2L Started Overheating

I have a 95' Grand Cherokee, V8 5.2L. Recently, it started overheating and was diagnosed as a head gasket issue at a shop. I ended up replacing the head gasket, thermostat, and water pump. (The radiator, top radiator hose, and radiator cap were replaced within the last year as well.) Despite the repairs, the coolant in the reservoir does not move. The Jeep overheats and there is a squealing noise coming from what may be the water pump. There is also a slight leakage of coolant near the water pump bypass hose, but does not seem to be coming from the hose itself. What else am I missing?
