93' Grand Cherokee does not auto-shift to high gear until I hit 50-mph.

  • Anonymous Jan 05, 2010

    There is an Overdrive button on the dash that works fine. When the transmission is in "D" it automatically shifts to the next highest gear ok, but does not shift to the 3rd highest gear until I hit 50 mph. I don't know if this is also called overdrive or just the 3rd automatic gear.

    Do you mean overdrive? It's not suppose to.

This is most likely the throttle position sensor. It sounds odd I know, but the throttle position sensor helps tell the transmission when to shift. This same thing happened to my Jeep. The sensor is located on the intake manifold on the engine and costs around 45 bucks.

To the guy who spent 2300 dollars getting a transmission rebuilt: They saw you coming and you got totally screwed over. I can get a cherokee transmission rebuilt any day of the week in the range of 800 to 1000 dollars. WOW check out your shops and mechanics a little better before you jump into a rip off.

Sounds like a serious transmission problem. I had one ,('90'), that did something like that. It didn't want to go into 3rd gear right away, and then 3rd went out altogether. Had it rebuilt, but it cost $2300.00 dollars.

I don't think my 95 Grand Cherokee is shifting into overdrive all the time. Can you tell me what the RPMs should be for it running 65 MPH?

Depending on differential gearing, most run at about 21 hundred rpms @65. Overdrive usually shifts in at around 45mph. To see if it is engaged, while doing about 50, lightly tap the brake. That should momentarily disengage the od and the rpm's should increase for a moment. @45, you should notice the rpm drop when it engages initially.

I have a 1999 Jeep Cherokee with 4 wheel drive, when I start out the transmission takes a long time to shift into high gear, probably around 4o to 50 MPH. Someone said it is the transmission modual and has...

This is possible, to check the valve by going under your jeep and looking at the back part of the transmission. You will see a valve with a vacuum line going to it, it is usually located at rear of trans just above trans pan. To check pull vacuum line off, if fluid comes out the valve is bad and needs to be replaced. They can be purchased at most auto parts stores readily. If no fluid the trans may just need serviced.

Is a 1996 jeep cherokee a towable vehicle? {auto trans.}

does your transfer case have a neutral? if so shift to neutral and it can be towed.if its alltime 4x4 or auto then not above 35 mph for more than 50 miles. if this is to be a tow vehicle i strongly suggest a car trailer. the maintinance is less its easier to pull and hook up and there is no wear and tear on your vehicle.

Hi, Why on the newer 06-08 grand cherokee limited with the Hemi, Quadra Drive II, does it take until about 65 MPH for it to go into overdrive or 5th gear?

how high does it rev before it goes into 5th gear? if it's not too high, could just be a long gear, and completely normal, or otherwise you may have a bur on your shift valve causing it to not want to shift normally. for that case you have to pull the trans and grind the bur off, or if it's under warranty fight with the dealership until they agree to.

Jeep 4wd auto trans

while moving about 2-5 mph, shift your transmission into neutral but keep the vehicle rolling, then move the transfer case shift from 4HI to 2HI.
