When I accelerate my RPM's go up to about 2,000 which is where it should be for regular highway accelerating. But as soon as it hits 2,000, it drops down to about 1,100 and stays that low even if I accelerate. I need to floor it so it shifts for me to accelerate. I know that's not normal.. anyone idea what's going on?

 

That sounds like you might need to adjust your TV cable

 

How do I go about doing that? and how will I know if its adjusted enough?

 

Look at your throttle body. There's a cable that goes from the throttle lever to the transmission. It has a little D-shaped button on the 'self-adjuster' which is mounted on the manifold. With engine OFF, Push that button and slide the little 'nipple' where the cable comes out in towards the adjuster. Once it's all the way in, release the button, and move your throttle to wide open position.(again, engine is OFF for this adjustment) You'll hear the adjuster 'ratchet' or click-click as the cable is pulled out. That's it! Test drive to see if shifting has improved. Hope that helps

 

How do I know if it even needs adjusting?

 

Well, the symptoms you described could be one indication. "When I accelerate my RPM's go up to about 2,000 which is where it should be for regular highway accelerating. But as soon as it hits 2,000, it drops down to about 1,100 and stays that low even if I accelerate."
Does your Jeep have overdrive? If so, that seems pretty normal. It would shift into overdrive around or above 50mph.
"I need to floor it so it shifts for me to accelerate."
That is what led me to believe your TV cable may need adjustment. If i'm in overdrive, I don't need to 'floor it' for it to downshift into 3rd. Probably about 3/4 pedal or so, but well before wide open throttle.
If you don't feel comfortable adjusting it, then don't. If not adjusted correctly, it can cause too early, or too late shifts, and can result in damage to the transmission. But.. it is a really easy adjustment. You almost can't do it wrong as it's a 'self adjusting' type thing.
Maybe you could try a fluid/filter change? Look at the tranny dipstick.. the fluid should be a light red, not burnt smelling and of course at the correct level. Check when hot, on a level surface, idling in park or neutral (it'll say on the stick) Post what you find out

 

I adjusted it easy enough.. just waiting to test drive it. thanks for the info. I'll let you know how it drives now. I'll be sure to check my tranny fluid too.

 

Fingers crossed..

 

I hate to say it but that didn't fit ix :/

 

 

same problem, same fix.. you adjusted the TV cable and it still isn't shifting properly? What vehicle are you referring to? Year/model/engine/trans etc?

 

So whos XJ is acting up, and what year is it?

 

 

Check the TPS. Use the smallest safety pin you can when backprobing the connector. Too big and you can damage the connector.

 

every sensor in the throttle body is new the iac tps etc I already tried a different tps and still the same problem
