#4473 of 4619 High rpm /transmission engagement by smokebee Jun 06, 2009 (7:37 am)
These trans have some computer control exerted on them. Try this. Take the negative battery cable off. let set 5 min or so. reconnect. put key in switch and with your foot on the brake turn key(not to start)--on off, on off, on off, release the foot brake. start engine and see if trans engages a low RPM. The steps you have performed cause a reset of the computer---it has cured problems in many instances. S Swann

#4475 of 4619 oxygen sensor location 1995 5.2 L by ebizsearch Jun 11, 2009 (7:11 am)
Have a 1995 jeep grand cherokee with V-8, 318 cid. (5.2 L). Can not find location of the oxygen sensor to replace it. Can anyone tell me where it is. Is access from top or under side? Can I get to it without other parts removal? Thanks for any help. Replies to this message: smokebee (Jun 11, 2009 10:41 am) ebizsearch (Jun 11, 2009 3:16 pm)

Replying to: ebizsearch (Jun 11, 2009 7:11 am) Should be located in front exhaust pipe near where it ties into exhaust manifold. A secondary downstream sensor will be located after the cat converter. S Swann Replies to this message: ebizsearch (Jun 11, 2009 3:16 pm)

Replying to: smokebee (Jun 11, 2009 10:41 am) Thanks for the comeback. I will get under again and look. It must be on the right side manifold and where the crossover pipe to the left side is. Must be on the top side of pipe where it is hard to see. Thanks again. ebizsearch
#4479 of 4619 1993 Jeep Grand Cherokee Too Cool by frustrated93 Jun 20, 2009 (8:36 pm)
I picked up my 93 Grand Cherokee just over a month ago and it has been a nightmare. The computer works against everything I do. The Jeep was overheating, so I put in a new radiator, hoses, heater hoses and both engine coolant temperature sensors. I also put in a new cooler (160 degree) thermostat. My overheating issues have gone away and I was able to drive the thing for a few days. I drove it the other day and had no issues, but several hours later when I went to start it up it wouldn't and still wont. The engine codes are telling me that the engine is running too cool. Does anybody know how I can get around this issue? How do I get the computer to allow the Jeep to start? Atleast when it was getting too hot, I only had to wait until it cooled down for the computer to allow it to start. Now that it is running too cool I am lost as to what to do. I appreciate any assistance. Thanks!
#4480 of 4619 List that never ends... by mannymiami305 Jun 23, 2009 (10:46 pm)
I have an 01 JGC with almost 100k on it. I have previously wrote that it was hit by a flood and I myself did a ATF change on it. Now only a couple hundred miles on it and the car dies when at a street light, has to have a little cranking in order to run the engine, and transmission doesn't seem to change gears on time. This list goes on and I don't know what else to think of doing to it. I Love my Jeep cause it has pushed its way from Miami to Houston without a problem and I honestly believe that it's like a climate change that has affected it. It's hard to believe but it seems like it and I laugh about it. I have made a list of the things that it has and well I have been told many different things that can fix the problem but no solution. I guess the only solution is to go to a mechanic and make him check it out but we all know that mechanics nowadays are hard to trust. I would like to know what should I do? Suggestions anyone?

Replying to: mannymiami305 (Jun 23, 2009 10:46 pm) Hey, MM305---I, too, had a flood situation with 99 JGC--4.0 six engine. Water got up to just about CD level on the radio.(total underwater time about 2 hours) I drained the engine, tranny, rear end, gas tank, air manifold, fuel rail,cylinders and whatever---except I failed to disconnect the transmission cooler lines and blow the water/oil mix out. Got it to runnning okay---shifted okay--for awhile.Then got to where it would not shift properly, like yours. Finally took it to tranny shop. What little water remained in the cooler tubes got to the clutch plates and destroyed them. Replaced tranny/torque converter unit and it runs great.Cost was $1500 for the tranny with six month warranty(well past that now). It had 106,000 miles at time of flood and now has over 120,000. Good luck-----------Smokey Swann-Odessa, Tx
#4482 of 4619 Lack of Transmission Dipstick by shopdog97 Jun 26, 2009 (11:22 am)
This is not Earth-shattering, but can anyone tell my why the geniuses at Chrysler CHOSE NOT to put a transmission dipstick on our 07' Grand Cherokee? All it has is a plug where the dipstick should be that says "Dealer use only" on it. Now why is that? This is the 3.7 V-6 engine with the 5 speed automatic. So I am not allowed to check my own transmission fluid level? I asked my service advisor at the dealership and I got some stupid response that amounted to "well you really don't need to know that', Why don't I need or want to know that? Now the thing only has 10,000K on it right now, but I'm used to doing things myself, and I like to be informed MYSELF! I wonder if there is one available from Chrysler(I never checked on it) Now imagine if there was no engine oil dipstick either. They couldn't do away with that, could they?? And the one they do have there is the chintziest piece of metal I ever saw for a dipstick. Bring back the OLD DAYS, please!!!!!!!!!
