#975 of 1100 "Shutter" when Jeep gets to 40 mph +
Jun 08, 2012 (2:15 pm)
I have a 2008 Jeep Grand Cherokee Limited with the 5.7L Hemi w/ 192K on it. The Jeep has been running and performing perfectly until a couple of months ago when I took it to the local Chrysler Dealer to service the transmission. As soon as I picked it up I noticed there was what they are calling a "shutter", at 40+ mph. It feels and sounds like the car is going over rumble strips, this goes on intermitently. It has been at the Chrysler garage for over 7 weeks and they can't figure out what's wrong with it. They have replaced the converter, a valve in the transmission, all fluids and filters, replaced all 16 spark plugs. Now they're are trying to tell me it's the gas, so they keep having me pay to fill it up while they drive it around. As you can see by the mileage I drive I put a lot of gas in it, I fill up at different gas stations and run either 89 or premium in it. It doesn't feel to me like it is coming from the engine, could the AWD be jumping in and out?
I did e-mail the CEO of Chrysler and he responded within a few hours, Monday they are flying a tech in to look at my car.
Any ideas would be a great help.
#976 of 1100 2011 Grand Cherokee transmission slipping
Jun 11, 2012 (7:08 pm)
I have a '11 Grand Cherokee with a 5.7L with 9,000 miles on it. For the past several months the transmission will fail to engage for 3-6 seconds when it is cold. On most days I will shift it into reverse and it will engage in 3-6 seconds then some days it will engage immediately then it will disengage for 3-6 seconds before I can continue driving. The dealership is trying to convince me that this is acceptable. The transmission is sometimes "clunky" when coming to a stop or starting from a stop. One morning I shifted the transmission into drive and about five seconds later the indicator showed that it was in fourth, when I tried to shift it either up or down nothing happened. It remained in fourth until I turned off the engine and re-started it. I also has had an issue with it shifting into overdrive one day while driving at highway speeds. Last week the dealer flashed the transmission with a new software version (which they said had just come out that day) and they tried to convince me that this would resolve all of the issue but it didn't. I have contacted Chrysler customer care and they asked if had driven any other 2011 GC's to see if this was just mine or all GC's. Has anyone else encountered this type of transmission issues and how were they resolved or is this "normal" of all 2011's with the 5.7L

I went through that shutter issue with my 2011 JGC (V6). It would shutter as it shifted and when it is at 2000rpm. They started changing parts but the issue was resolved by changing the drive shaft. You may want to suggest this to them. The drive shaft issue seems to be common. Pretty sad commentary for the reliability of the JGC.
#978 of 1100 Transmission fail...Maybe???

I have a 1995 Jeep Grand Cherokee Laredo that has about 210,000 miles on it. I bought it and drove it for about 4,000 miles before it started having some problems. One day I was towing a trailer and the engine started to get really hot and overheat. I pulled over and coolant was leaking out all over the ground and boiling. Ever since that day the Jeep has been overheating for everyday use. I drove it for about 4 months like that always being very careful to not let it get past a certain point and to keep the coolant full. I recently went to a mechanic to see what the problem was. They checked to see if I had a blown head gasket which I didn't thank goodness... They also hooked it up to a computer to check if it was the transmission. They said it wasn't. So the next thing they said it might be was the temperature gauge. I agreed to change the temperature gauge and it seemed like everything was fine. It ran great for the next 5 days! Like it never had a problem. All the sudden the other day I was driving it and I lost all power.
When I push on the gas the RPM's go way up but the truck moves like a slug. I can so about 15-20 MPH and thats it. As I was trying to get it home I had to climb a hill to get it to the house it only made it half way up and stopped. I put my foot on the brake and waited a moment then I got it to go the rest of the way. At this point I am to scared to drive th truck anywhere because I dont want to get stranded.
Has anyone had this problem before or know what it might be?

To actually boil the coolant does not indicate a problem with the temperature gauge. Something is blocking the passage of water and it's probably a faulty thermostat, usually found between the engine block and the radiator hose. Your driving difficulty is no doubt a fault in the solenoids in the gearbox that get seized up due to overheated and burned gearbox oil.. The oil should be changed annually. It will be necessary to drain the old oil from the gearbox and probably fit a new set of solenoids (not expensive - at least here in Mexico) as a kit. i hope this helps.

Your message was very helpful!I actually got the thermostat fixed not the temperature gauge. my bad.... I havent driven it in awhile. I started it up today and drove it around the block and it seemed to go just fine. It did pull a little and have some trouble shifting into the gears. Then when I got back to the house to park it it started to make a whineing noise from underneath the truck. I think it was coming from the driver side. It only made the noise if I was in drive or reverse. If you still think it might be the burned gearbox oil and the solenoids I will be very happy!
Thank you so much for your advise! Seems like every mechanic wants to do the most expensive thing to fix it.

I have a similar problem. I just bought a 2012 Grand Cherokee Overland and my transmission takes 3 - 6 seconds to engage, but the problem is not consistent. So as you can imagine, the dealer cannot replicate the problem and the computer isn't recognizing any issues. One day I backed out of my driveway, stopped, put it in drive and it shifted so hard that the car died. It's the only time that has happened, but at least once a day, the hesitation on engaging occurs. I put it in drive or reverse and will just move slowly with the engine reving up, then I let off the gas until I can feel it actually fully engage. I'm about at my wits end. I only have a few thousand miles on it.

I also own a 2008 Grand Cherokee with 3.7 litre engine which is having the same issue. Were you able to determine the root of the problem? If so, what was the solution?

It ended up being my ignition and shifter module both.
#984 of 1100 2012 Grand Cherokee With A Shudder
Jul 06, 2012 (7:03 am)
My 2012 Grand Cherokee has 7600 miles and from day one experienced odd transmission issues. I have the Hemi V8/Overland package. About 1 in every 6 starts the vehicle lurches forward as if the trannie wasn't all the way in park. Dealer says "thats normal". When traveling at highways speeds the vehicle seems to be in a constant battle with itself as the cylinder deactivation and the transmission try to find a happy place. If you gently accelerate from 60 to 65, the transmission shudders; so much so passengers think that I am unsteadily applying the gas. Typically I use the cruise control on highway driving to help reduce the issues. Driving in traffic is another story. In daily driving when shifting from park to drive or drive to park, the transmission engages hard and often sounds like two weights dropping on top of each other. Dealer again says "sensors indicated all is normal". Often there is vibration during acceleration and gear shifts tend to "drop" into the next gear vs. modulate into next gear. Anyone else experiencing this problem?
