Shift solenoid. Hard to tell with one is bad because there is no way to really test them. However your may have 4 solenoids in your transmission.

It will continue to repeat the same problems because it was not designed right.

NO, just replace the Vehicle Speed Sensor, it is on the transmission.

SOURCE: Allroad Tiptronic Gearbox "holding" gears before changing up.

Have you had the vehicle put on a diagnostic machine, does the car feel slugish, any lack of power, we have seen a lot of these vehicles with air mass sensor faults. When they fail they do not show a code but with the right scanner they can be seen not working. This affects the gearchange because the ecu does not have the correct data to shift. Of course it could also be the transmission is in need of overhaul. but i would take it to a good diagnostic garage first. It is not uncommon for the air mass sensor to fail after it has been disturbed or knocked in the workshop. we have never found out why.

93 honda accord ex won't upshift at all replace tcu same issues . At first was fine now it's worse after changed tcu. Is the tranny shot . Also replaced vsp and seloniods? Any ideas ?


if there are no noises and the transmission shifts properly when it works , then a replacement transmission should be the last consideration
controls in the transmission are electronic and are shared by the VSS ( vehicle speed sensor ) . TR sensor ( transmission ratio sensor) and the TCM
the wiring may be your problem and a problem vacuum actuator is indicated as that tells the rest when to change in relation to throttle opening
if you have not changed the oil in the last 5 years or 60,000 miles , that would be a good place to start

Cold auto Transmission won't shift into 3 gear until after driving 1 mile or so (driving at about 35 mgh) pickup then downshifts from 3 to 2nd then back to 3rd a few times untill I get to work (7 miles...


Sounds like a bad speed sensor. Perform an ODBII scan soon. ECU should delay upshift until coolant temp senses warm up. It will not work right unless a signal is present from speed sensor.

GMC Sonoma Automatic Transmission Problem


The transmission is this truck is a 4L60E. It is electronicly controled through several sensors. It will sense the load on the motor mainly through the TPS (throttle position sensor).It is not uncommon for you to have to really press the gas to make it down shift. Alot of the feeling depends on gear ratio in the rear end. The 4.3 is a very good engine, but it combined with a high gear rear end and overdrive may really seem under powered. You can put a programmer on it to change all the shift and power feel.If you are not having a hesitation issue then it will most likley not be the tps. You may just need a fuel and air filter, not knowing when it was last changed. The programmer is the best way to get the feeling you may be used to. Good Luck

My 99 dodge stratus shift to 2 and stays until i turn key off and on i can manual shift into 1 2 3 until i actually move in forward. if unhooked the battery already it didn't work any anserwer.


One or both of the speed sensors on transmission are bad. One is an input sensor, the other is the output sensor. If either one of these shows an open circuit (which they do when they go bad), then the transmission goes into Limp-Home mode and stays in 2nd gear. Those sensors are cheap enough where you should just go ahead and change both of them.
