Jeep Grand Cherokee Transmission Problems

    I have a 2003 Jeep Grand Cherokee Ovverland. I just changed the transmission fluid, dropped the pan changed both filters refilled and now the transmission is acting erractic. It seems slips/shifts erratically 4 and it gave me a check engine light that was incorrect ratio in second gear.

    Things I did.

    ATF +4 (Although it was synthetic)

    Checked level, thought it was high so I removed some and it still has the same condition

    I'm kind of lost as to what to do next, I hate to go to a repair shop with my tail between my legs... Any ideas??

    Thanks

    sounds that you put the o ring on the filter instead of the valve body like you should put a little grease on the o ring to hold in place install pump filter
  • I agree with you Eric. I also have an '05 5.7L JGC and I am very disappointed with it. I just got my "starter issue" (just one of a multitude of problems) resolved and now my transmission is acting up. I've had it in the shop a total of 16 times in 2 and a half years and now it's going back again. I'm beginning to think I need to trade mine in on a Toyota as well.

    :lemon:

  • I'm new to your forum & would like to say "greetings all"& hope you have the time & patience for a newbie.
    I just purchased a 2007 Jeep Grand Cherokee & due to time restraints didn't do my homework before the purchase.
    After reading all I can now I have a few questions.It seems in previous years the tranny has been a huge problem,also the brakes.Am wondering if these issues have been cleared up??It has the "Quadra Trac 1"system on it which is very confusing to me(& a bit troubling that it doesn't have "4 Low").I live in Wyoming so a good 4-wheel drive system is very important to say the least.
    Any answers & info. you can give me would be much appreciated....
    thanx

  • I have a 95 JGCL (4.0 6 cyl; 100K miles). Replaced the TCM last year when the O/D light would stay on and O/D did not work. Has worked fine for one year. Now O/D light/button on dash will intermittently go on and the transmission will start in drive (3rd gear?) unless I manually drop it to 1st gear. Seems to always happen when car is cold or not been running for overnight. Also stays in 3rd (high rpm) on the freeway and doesn't go into the 4th gear. After it warms up, it seems to operate normally intermittently.

    I have replaced the thermostat, checked the fluid levels. Could it be a bad TCM or is there something I am missing and should check; I've read about "temp sensing unit" and a "solenoid" on the trans. Could they be the culprit? Don't know where they are. Also, will the "On-Board Diagnostics systems" give me an indication of where I should be looking for a solution?? Any help is appreciated. I'm pulling my hair out looking for problem. And dealer wants to rebuild tranny for $3K.
  • I all so have 95 JGCL with 98,000 miles, and have the same problem.
    I have takeing it to AMCO and no help, and takeing to the Jeep dealer and left it for two days, and they can't find no problem.
    I am just about ready to get a Toyta and end this problem.

    I have a 99 Grand Cherokee Ltd, 4.7 ltr with about 98000 miles, has been a great vehicle. This morning I warmed it up about 15 minutes, hopped in, backed out of the drive way, and shifted into drive while drifting back slightly. It jerked pretty hard as it shifted. But when I took off, it was in a higher gear, like 2nd or 3rd, (3rd I think) and the check engine light came on. It did start shifting OK after that, but I took it to autozone to get the code read. the code is P1784, transmission mechanical failure, 1st and second, or 1st and reverse - there's 2 sections on there. Thats pretty much all they could tell me.

    I may have noticed it shifting funny yesterday when I first started out also but then it straightened out. So it seems that I'm having problems when the tranny is cold, but when it warms up it is OK. I did service it about 15000 miles ago. I haven't been able to find a more detailed explanation of the code, but it didn't come back on the way home from autozone. Can anybody point me in the right direction?

    Not a single reply. Why is that?
  • tuggajbtuggajb Posts: 646
    number on i dont live on my computer

    now as for the trans you probly should change the trans oil
    that trans is a tough trans the prob could be the shift solonides inside the trans could be sticking when cold all shifts are controled by these solonides

    I misunderstood how this forum worked. I saw posts above mine with 200 and 300 replies, and I thought they were brand new threads like mine. So I didn't understand why people were responding to those threads and bypassing mine, but now I see that those threads were started back in Aug and Sept.

    So thanx for responding tuggajb and I didn't mean anything personal. So by trans oil I assume you mean the transmission fluid?
  • tuggajbtuggajb Posts: 646
    right also do the pickup screens when you change the oil
  • For the past couple of weeks my transmission has been acting strange in my JCG. When I make a left turn, and it only seems to happen on left turns, my tachometer will free rev for a second usually up to 2500 - 3000 rpms and then the transmission engages properly. Less than a year ago I had the transmission fluid changed and I do not abuse the vehicle. With 65000 miles, I am confused as to what may be happening. Any help would be appreciated.

    sounds as if you are low on trans oil need to chech it like in book
  • I have a 2001 Grand Cherokee Limited V-8. How do you know if you have the 545RFE transmission with 5-speed automatic?
  • tuggajbtuggajb Posts: 646
    numbers stamped on left side just ubove oil pan also 45rfe has lable by numbers
  • my '94 grand Cherokee will sometimes shift in and out of overdrive once I reach crusing speed. This seems to happen between 55 & 65 with the most frequency. Any ideas?

    I have already tried adjusting the cable.
  • Can anyone help with a transmission problem with my 02 Grand Cherokee. Basically I can't get it out of Park and the shift lever button seems jammed. I recall on older models you had to knock the actual top of the handle part off and you could use a biro or something to make the switch work but before I take a hammer to this one can someone tell me what I should be doing. Thanks. Stewart
