Here's a great thread = I'm almost at the 'rebuild' stage myself...last Jeep I'll ever own. I'm sticking with my CRV from here on out! http://www.jeepsunlimited.com/forums/showthread.php?t=872990 You could have a bad throtle position sensor(all shifts), a bad seal in the transmission(2-3 shift), or the front band could be out of adjustment(1-2 shift).
I think you have to put your transmission on Neutral then shift to 4x4.
The shift solenoids are on the valve body inside the transmission. They are one of many things that can prevent the shift into overdrive.The shift solenoids are on the valve body inside the transmission. They are one of many things that can prevent the shift into overdrive.
Inside the transmission, on the valve body.
My jeep has the same problem (1998 xj) and a mechanic told me that you have to remove the tranmission pan to get to it, its up inside the transmission and if your goin to rep[lace it you might as well change your filter while your at it.
I had a problem shifting my suburban out of park. It ended up being the brake switch, it tells the transmission that you are pushing down the brake.
Yes, but there are several dozen other problems that are more likely
the transmission could be going out or slipping or your transmission fluid could be low
It retards / slows the timing up and makes the transmission shift hard. The engine has to be running right for the transmission to work right. It would really help to know the year. There could be other problems depending on the year.
There could be a number of reasons why your truck will not shift properly. There could be something wrong with your clutch or transmission.
The gears in your transmission may be sticking or worn out. This would cause your transmission to not be able to shift.
Several things can cause Chevrolet Corvette gear shifting problems. Broken gear shift linkage is the most common problem. Worn gears in the transmission is also common.
Allison transmission not shifting
The first thing you should do is change the transmission filter and fluid. A restricted trans filter can cause these problems. Do this before you worry about more expense things. Mark
Leaky transmission lines would cause the fluid level to drop and eventually cause the transmission not to shift and go.
what would transmission not to shift in to overdrive
The transmission in the Trailblazer could be low on fluid. The internal shifting mechanism could be giving problems as well, keeping the transmission from shifting into gear.
There are multiple things that could cause this problem, but if everything else seems to work fine, a good place to check would be the transmission and the shifter. Gears in the transmission could be blown and may not catch when you try to shift.
