You don't say what kind of car you have and some don't shift at higher speeds. Adjust the throtle cable and that should help if possible,.
Overdrive might not work on a 1992 Dakota because there is a problem with the transmission. The shift solenoid or a belt is not functioning properly inside the transmission.
Your car might kick when you shift from park to drive if your transmission fluid is low or very dirty. You might also have worn gears in the transmission.
Inside the transmission.
Does it stay stuck in first gear? or does it change and when it changes does it seem to wanna slip... if it does shift and it shifts smoothly it might be the kick down lever that's going to the transmission... sometimes they can become rusty making the vehicle shift at much higher RPMs then normal, making you think that its the transmission. If its not that then it might be the bands, or servos... im not a transmission exspert, but I do know somethings about them... Also, it might be the filter... sounds weird, I know, but always check fluid levels and filter as well, a clogged filter or old fluid can make the transmission seem bad, when its actually just the fluid and filter... lots of things to consider... thanks, hope ive helped.
I think it might have the same problem as my jeep ,,,it only go forward and when i shift the gear to reverse...it won't. Have ask around was told it have to be the transmission (Ugh! an expensive repair)
Shift solenoids are found on the transmission of the 1998 Honda Passport. The shift solenoids allow for smooth operation of the transmission when passing through the gears.
A transmission shift solenoid is found inside the transmission housing. Replacing the unit depends on the vehicle, some allow access underneath the car while others the solenoids can be reach from above the transmission.
Your transmission might automatically shift out of overdrive while driving on the interstate because of low transmission fluid. This issue might also occur because of a bad transmission sensor or overdrive sensor.
you might need a new one soon. but first check your transmission fluid.
Might be a problem with the brake/transmission interlock switch
The signs of a bad transmission in a Mazda might include hard shifting or a refusal to shift into certain gears. A revving of the motor during the shift can also be a sign of a bad transmission.
Your '01 Lincoln Town car might not shift gears because it is low on transmission fluid or because the transmission is damaged.
I think you are referring to a shift solenoid on a car. If so, this sends signals to the transmission computer to tell it when to shift gears either higher or lower depending on demand such as going uphill, passing or reaching cruise speed.
too low trans flid
A 2007 Chrysler Sebring that will not shift out of Park will probably need a shift solenoid replaced. This is inside the transmission and the transmission might have to be taken out of the vehicle to be fixed.
One of the reasons a transmission might not shift into overdrive could be a problem with the belt drive inside the transmission. Belt drives can be stretched over time. Another reason could be that the transmission fluid is low or very old or the filter is clogged.
there is no fuse that makes the transmission shift the transmission shifts on cylinoids and rpms
