Transmission not upshifting

My 1997 limited w/ quadratrac will not upshift, it lets the rpm's go to 5500 - 6000 without shifting so I have to keep screwing with the gas changing the pressure until it shifts. Any thoughts?


I wonder were that dirt road goes?

I had mine in the shoplast week because it wouldn't drop-down into 1st gear when I came to a stop. Shop replaced the governer and it is working fine. Do you have a 'Check Engine' light on?

Does any one have any ideas, I don't want to bring it to a shop, without attempting anything myself or at least getting some idea as to the actual problem. I am nervous about walking in with a "transmission problem" I won't know what to expect!!

Interesting. If there was a problem it should have switched to the limp home mode where it sticks in 3rd gear full time. I'm just talking out my rump but I'd check for loose plugs and hoses under the hood and on the tranny. Wish I could help.

Hi i am a new member. i had a friend that had a 97 that had the same problem with it reving up really high and not going any where. i belive they ended up replacing the whole trans. my trans has a lot of hard miles on it and it has held up though.

my name is Daniel i have a 97 Jeep Grand Cherokee V8 2wd, Green, custom intake bonnet with K&N cone, true duel side exit exhaust with dual high flow cats and magnaflows. my fastest time at the track is a 15.10 at 91 MPH and it made to 210 HP to the back tires.

Years ago, I experienced the same problem. It wouldn't upshift unless I tried to force it by backing off on the gas. Eventually, it got to the point where it simply slid into neutral. Finally, I began to experience the problem where it hesitated going into Reverse. All of this usually happened during the first few miles, before everything "warmed" up.

The problem turned out to be bad seals in the transmission. They dried out, allowing tranny fluid to leak past them. With the loss of hydraulic pressure, the trans wouldn't shift properly. Once fully warmed up, the seals softened enough to work most of the time.

I was told that, regardless of what the manufacturer says, you need to change the trans fluid yearly. Apparently, there are additives to keep the seals moist. Sounds like a simple solution, but it appears to work. I've always tried to change the fluid as regularly as possible and have avoided the problem since.

Of course, replacing the seals requires almost a complete rebuild of the trans.
