#462 of 1100 Jeep Grand Cherokee Transmission Leak
Nov 10, 2009 (10:55 am)
I have an 2006 Jeep Grand Cherokee with approx 33,000 miles. I moved my car this morning and there was a good size puddle of transmission fluid under it. Upon inspection it looks like the pan gasket is the problem, I checked and all the bolts are tight. Anyone heard of a gasket going bad so soon?
I tried to check the fluid level and where the dip stick should be there is a cap that reads "For Dealer Use"
Can I get one at any auto parts store?
How much fluid does a grand cherokee take, the manual doesnt specify?
How much torque do I use when putting the pan back on?
Thanks in advance for your help

At 33,000 miles you shouldn't be having problems with any gasket. Is it possible a silicone type gasket was used by the manufacturer instead of a pre-cut one? I was surprised to hear some newer vehicles don't have a dipstick for the transmission. A few pages which discuss this and have some parts numbers are link title and link title (see page bottom). Two dipstick sources are link title and link title. Like you mentioned, I would try a local auto parts store first. Also, Googling "dipstick 8863B" brings up a lot of hits, although I'm not sure if that's the correct dipstick number for your Jeep. As for tightening torque, I only go slightly tighter than "wrist tight" using a srewdriver type handle with socket for older precut gaskets, but in your case I would try to obtain that information from a service manual or dealer.

My sisters vehicle has no dipstick, they want you to go to the garage and get it checked and have them do it. And I would do the same for torquing, just finger tight the snug them with a wrech or socket don't torque on them they break and leak, it works for me i have no leaks you should have no problem. My 95 I put in about 3.5 quarts almost 4, then checked if it was on the dipstick, but you should add a quart at a time then check it you have on the dipstick, then drive it, check it running and added if needed. Good luck!

Today when I drove it and parked, I cycled the key and it gave me VSS code and Governor Pressure sensor offset drift. My brother and I think you are right about the connection, but we think a ground, because of the ground for my windows going(still didn't find) and moving wires causes different things so. I'm going to a shop tomarrow where he gets his diagrams and get a ground diagram for all the grounds and whatever will help. And start here tracing wires (fun). I'll let you know!

Thanks for the help, I'll let you know how I make out. I'm going to replace the gasket this weekend. I still haven't been able to find out how much transmission fluid I need. Will the autoparts store know that or do you know where I can find it?
Any other thoughts on why I might be leaking fluid?
I spent a good 45 min. looking around. The entire bottom of the transmission pan was wet as well as the gasket all the way around but nothing above the gasket had fluid on it. The only other spot was the plate that covers a wire connection on the corner of that pan was covered.

Not sure about the auto parts store knowing as they vary widely. Still, it doesn't hurt to ask. Sometimes one of their more experienced employees might know where to find it, especially if they want to sell you tranny fluid. They might even have one of the lower cost service manuals. I don't know how much the newer vehicle owners manuals have been dumbed down, but the earlier ones used to show fluid/oil capacities in the back. First thing would be to find and make sure of the model transmission you have. Then, you could ask the dealer service department (good luck), and if that falls through, Google the transmission model number for any info you can find on the web. Many times I've seen transmission manuals listed. In the end, what's going to matter is what's shown on the dipstick, so getting more than you need is not a problem.
Myself, If I feel I'm going to keep a vehicle for a fair amount of time, I always invest in the factory service manual. No, they're not cheap, but you can rely on them for accurate information. In my view, they pay for themselves.
As for the leak, is it possible to be coming from above, only to be blown on the pan by airflow? Only other "common" source of a leak I can think of would be cooling lines. Another possibility is the fluid could be from something else other than transmission fluid. Transmission pans usually don't contain a fluid level higher that the top of the pan (gasket area). If the gasket has an open spot, it's probably the fluid sloshing around and spilling out. Clean the pan best you can, then observe it after driving a little. Good luck.

I have the Ground diagram and alot of things are tied together like the power windows, they are on the same ground as the VSS, but I didn't see the TPS in this. I checked the ground associated with this components, and they are like new. So I pulled the cover off of the harness from the sensors on the Intake to the PCM. By the head they or soaked in oil, and the rest look good, my next step is to trece wires and check the splices. Any other suggestions.

Auto parts stores have the capacities and the fluid that vehicle needs every time I ask. I would check all the cooler lines first that easier that dropping the pan. If they are not wet though they probely are not leaking. Also is the connection on the pan or the case of the transmission, make sure that don't leak. Good luck!

Just curious, if you unplug the TPS, does it affect the engine at all? I'm wondering if it's still "in the loop", or if the PCM is in default mode somehow. Another thought, if you don't see a ground wire/strap from the engine to the frame/body, why not ground them together to see what happens? I'm probably repeating what you've already tried, but can't think of anything more at this time than what you're already doing. Keep plugging away!

Yes when you unplug it it idles high, and the throttle response is slow. Also the guy I got the ground diagram off of said that PCM's have bolts going through the fire wall and that's how they ground. You think I should run a wire from the head over to the fire wall. I'll try that maybe there's a ground I missed and is corroded.
