Question about 2002 Jeep Grand Cherokee

1 Answer

Transmission stays in first gear

I own a 2002 Jeep Grand Cherokee Laredo, 3 months ago I was told I had a small pinhole in my radiator, never got it looked at or fixed, now my oil pressure gage has shot up to "H" (High) and the jeep will stay in first gear until I rev up the rpms to 4 then will it switch gears and go on driving just fine (I only have to do this when the jeep is first started up or I come to a stop sign or stop light). I have been told it is the throdle sensor or vaccum hose or the (3) cilinders in the transmission need to be replaced. I have been quoted anywhere from $50 to $1500.00 to fix the problem, need help please!!!!!

    I have the same problem exactly. The transmission shop in SIlver Spring (SUPERIOR) mentioned this is common for Jeep GC over 100k mile. The oil guage HIGH (H) is a pressure swithc ($36 for the part - check the oil level often). Transmission replacement is recommended, unless you have a local transmission shop that has a reputation of doing solid work for a re-build. ($1875 was my solution).

It would cost less to replace the transmission than to have that one rebuilt shop around and see if you cant find a trans for it and have someone put it in for you

1999 grand cherokee laredo overheating when idling for 15 min. or so. Not when driving, everything ok. radiator replaced about 8-9 months ago, water pump pretty new, and extra electric fan worked on about...


Chanches are it is probably the fan. Anything over 15 miles an hour the fan is no longer needed. I would get a cheap hydrometer and make sure your antifreeze is still good.

My 2002 jeep grand cherokee laredo wull not start shutdown 2 days ago checked all fuses but the ecu fuses don't know how to find them


According with your other quesions, the DTC P1491 code is actually radiator fan control relay circuit.
Soft reset if the battery disconnect would have erased the code; the first thing I would replace for that code (fan relay).
Additionally, its possible thta your THEFT system is activated, check owners manual to disarm. Check details here:
- Grand Cherokee fuses

- Diagnostic Trouble Codes

Hope this helps.

Eratic shifting of gears at speeds of 55 to 75


I would check the transmission fluid level and color, should be a nice clear red color. You may need to have the filter replaced. Possibly some internal transmission problem also.

I have 2002 jeep cherokee and radiator fan stays on when jeep is off. Pulled fuse and it shuts off, put fuse back in it turns on. Someone told me it was the realy switch. Where is it located?


the relay switch is located behind the passenger side head light. I just replaced mine 2 weeks ago. The manual says to remove the bumper, but this is way too much work. I cut a 3" x 5" hole in the plastic with a dremel tool. Start 6" from the fender make a small hole so you can see it. It is a blue box 2" square.
The price for the relay in Canada is $110.00, dealer only!

It's a transmission related problem, that you should have looked at a.s.a.p. to avoid costly transmission repairs down the road. Have it scanned at a reputable transmission repair place, dealer, or mechanic you trust. The drain pan will have to come off to perform repair, so have a transmission service (filter & fluid) done while your at it, unless it was done recently.
