    prob just need to retighen up the pan bolts
  • One year old, shouldn't be leaking. (If) fluid is leaking from between pan, gasket and transmission - seal is breached. Fiber or cork gasket maybe snug bolts slightly. Should be under warranty, let the dealer deal with it.
    Anytime fluid gets between surfaces it helps to act as a vehicle causing more fluid to flow through the same breach, make sense?
    At one year - maybe 25k on the odometer, new filter wouldn't hurt anyway.
    Cheers!
  • Check trans. fluid level, color and odor. Add if necessary and if fluid smells burnt, check it or have it checked,(maybe band burnt), possibly low level and clean battery terminals.
  • recently had transmission flush battery is good its yellow top optima battery my negative terminal is cracked
    could this resolve in poor connectivity or maybe i need alternater still original i also added lucas antislip transmission fluid it has 2020000km

    it has 2020000 km

    I think you put an extra digit in there! Either that or you have a VERY remarkable vehicle. :)

  • I also have a new 2007 Grand Cherokee that has developed a transmission oil leak showing up on the bottom of the pan. The oil appears to be from the pan seal, but I am not sure. Do not see any fluid above the pan, just on the bottom of the pan and on the ground. I have 14,000 miles on the Jeep, and just noticed the fluid leak. Is this a common problem with the 2007 Jeep GC? Did tightening the pan bolts fix the problem?

  • The description of your symptoms are basically what I am seeing. Actually after further inspection, I only noticed the oil from on one side (driver's side) of the pan. The other edges don't show any signs of leakage. This is my first Jeep GC, so I don't know if this is truly a common issue regarding transmission fluid leaks. My vehicle is also close to 14K miles.

    I have not tightened the bolts because I don't know what the torque is. I could get a torque wrench to verify this, but then I am thinking that since I am still under warranty to have the dealer take care of this and get this over with. On the other hand, I am not afraid to get underneath the car and verify the torque, and if that doesn't solve it, to remove the pan, clean the old sealant off, and reinstall it with this Mopar RTV sealant I once picked up from the dealer which is specially formulated for use with transmission fluid. My take on this is that it can't be any more difficult than an oil change, which I do anyways, except for knowing the sequence of how to tighten the bolts back on. Guess I need to get a Chilton's car manual to find out.

  • 14k - I realize it may be difficult to be without your Jeep for a day, but, you really might consider letting the dealer take care of it. That's what warranties are for. Would be nice for them to know if a manufacturing process failed somewhere along the "line". (cracked pan, housing, bad batch of sealant etc.), may be need for recall or such.

    Ya - RIGHT!

    Crawl under that puppy and learn all you can about it. After all.......
    You never know when you'll have to make repairs, neck deep in snow, mud, weeds and such. If you repair it yourself, and KNOW that you done it correct, any more leaks you'll be able to eliminate THAT scenario. Take time, no short-cuts, and do it right.
    Oh ya, be careful & safe.

    Cheers!
  • hello to anyone who can help. my sons 94 grand cherokee will not go in reverse,but will move forward. when shifted into reverse there seems like there is a load on the engine,but car does not move no matter how much gas you give it. any ideas?????
  • 2001 jeep grand cherokee - 4.0 engine - The transmission seemed to slip on rare occasions at about 20 MPH not on acceleration. The speed sensor light comes on but eventually goes off. My mechanic changed the speed sensor wires and then the speed sensor but nothing changed. Wet or damp weather my be part of the problem. Any ideas.
  • no idea how to help you but have the same problem with daughters machine. hers is a 97 grand cherokee.

    I have a 1993 jeep grand cherokee, it drives fine but when stopped and left in park it rolls away with a jerking motion. Someone mentioned something about a parking pin in the transmission might be broke.....if anyone has any advise or suggestions that would be great.

    Hi, I have a 2001 Jeep Grand Cherokee Laredo 4.0L. We bought it used about a year ago and have a question. When you full throttle the engine, the RPMs don't go over 4,000. The maximum torque range for the engine is 3-4 thousand. It seems that the transmission is trying to keep it there. It shifts through 1st,2nd,3rd gear like that and then shifts down to the alternate second gear which bring the RPMs to 4500. Once the RPMs reach redline it shifts to 4th and 5th. Is this normal? I think maybe the TV cable needs to be adjusted. I tried reseting the computer but it still does it. Please help :sick:

    I have this exact problem with a 95 JGCL AWD 5.2L. 166K miles.

    My trans shifts at high RPM's, and now I seem to have lost OD/4th gear entirely. It also seems to engage into reverse, gets a little momentum, and then loses reverse entirely. I've been parking up hill.

    I've changed the filter/fluid, and then repeated after 15K miles. When I changed it last, there was a burned smell in the pan area.

    I've been reading on here about Throttle position sensors, frozen sylanoids, etc. If you get it straightened out, post it. I am handy with the tools, but can't diagnose worth a sheet.

    I love my snowmobile, often drive through the yard just to show off I can in a foot or so of snow. Want to get another 100K, without Trans replacement.

    in service manual looks as if you want to change the tps (throtal position switch first as that is the easeyest to do)

    I will try to figure it out. I too don't want to have to replace the tranny at only 139000 miles.
  • I have a 95 JGC Limited with the 5.2L V8 with 150k miles. Recently the tranny has been idling rough and jumping in and out of gear when im at a stop but in drive. I was thinking it may be the torque converter but im not sure since its 4wd. Anybody else have this problem or know what might be going on?
  • 1993 Jeep Grand Cherokee 5.2. I was pulling a trailer up the hill and I noticed that the transmission wasn't dropping to a lower gear and had a slight shudder. It bogged down to about 15 mph when a neighbor flagged me down that flames were coming from under the Jeep. Opening the hood they were coming up behind the engine. We were able to put the fire out with snow and I let it cool down and it ran again to drive the mile to my house.

    Is this a problem with the transmission or transfer case? I dropped it down in to 4X low but I still wasn't getting the low-end torque. A similar problem happened 2 weeks ago and then I noticed that putting it into low gear going down hill did not slow the Jeep down much. Thanks...Sing

    My 94 JGC is doing the exact same thing today. When it's in park, it starts rolling slowly, even if you leave the emergency break on. Did you ever figure out what it is? I had my transmission rebuilt 2 years ago, and the warranty just expired last month.
