SOURCE: Gear shifting problem

The 1st thing to do is have a test run on the transmission control module to see if any trouble codes are present, next have you ever serviced the transmission, fluid and filter change, should be done at 60,000 miles, on occasion this can cure problems like yours.

SOURCE: automatic transmission< while in drive wont shift

change your transmission filter: no or, very little movement and, no shifting indicates a clogged hydrolic circuit
do not continue to drive your car at that rpm until you fix this as engine damage can occur

Is there a Fuse for a/t shifting, 2000 vw jetta


From the tear of the car I guess you have the 4-speed automatic. That transmission is not one of the most reliable ones...it has an internal wiring harness with relays attached to it, that are in control of what gear to select, based on input from an internal speed sensor, engine speed sensor and wheel speed sensor. There is also an issue with VW claiming that the transmission "is filled for life", which is absolute B.S. You have to change the transmission fluid and the filter at least every 60K or you will face an expensive rebuild. Have your mechanic scan the computer for fault codes related to the transmission and change the fluid and filter when the problem got fixed.

Truck won't shift into gear


Oh, boy - this could be pricey!! Either the shift linkage came apart or the Transmission went bad. Find the shift linkage rod coming through the firewall and follow it to the transmission. Check for connection to the trans and if the grommets are good. If both are good, then you'll need to get it to a transmission shop to be investigated. If no Linkage rod, then your trans is 'wired' meaning it is electronically controlled, and the shift solenoid ( or other component)is bad or has a bad connection. If this is the case, locate the shift solenoid on the side of the trans and inspect the wires - if any are burnt or lumpy, that would be bad and need replacement.
Hope this helps!!

Transmission will not shift into 3rd gear


no problems before the mud deal but problems after the mud deal means that the problems started in the mud
check for mud in connections , wires disconnected , harness problems, vacuum hose to actuator broken or missing
run the fault codes to help point to a problem area
the transmission is sealed so there will be no need to change the oil or filter--just clean and check everything that is mud affected

My 1993 Gmc Sierra 2500 automatic first gear shifts hard also from park to drive others gears are smooth i have overdrive


The gear shift lever indicators tell you what gear you have an automatic transmission in on your vehicle. The shift solenoid tells the transmission when to shift gears and what gear to shift into. Newer model automatic transmissions have electronic shift solenoids that are activated and change gears based on the speed the vehicle is traveling. Troubleshooting either one of these transmission components is relatively easy if you know a little about automobile mechanics. With the right tools, you can determine whether the transmission shift solenoid is having a problem. Gear shift indicator problems can be determined simply by moving the gears into their designated position.
Transmission Shift Solenoid
  • 1 Raise each corner of the vehicle up with the car jack and place jack stands under the frame. Make sure the car is raised high enough so you can work under the car freely.
  • 2 Slide the drain pan under the transmission fluid drain plug. Remove the drain plug with a ratchet and socket, and let all the fluid drain out of the transmission. Remove the transmission pan bolts with a ratchet and socket. Pull the pan away from the bottom of the transmission, revealing the transmission shift solenoid.
  • 3 Wipe off the shift solenoid with a shop towel. Disconnect one of the two plugs that attaches to the shift solenoid. Turn the knob on the volt meter to the ohms setting, so resistance can be measured. Set the volt meter on 200.
  • 4 Take the black lead of the volt meter and touch the negative battery terminal wire. Take the red lead of volt meter and slide the tip into the terminal plug you just disconnected from the shift solenoid. Look at the reading you get on the digital display of your volt meter. Determine if the reading is between 12 and 25. Readings below 12 or above 25 tell you that the shift solenoid is not working. Reattach the plug to the shift solenoid and pull the second plug attached to the solenoid. Perform the same procedures on this plug wire. Replace the transmission shift solenoid after determining it is bad.
Gear Shift Indicator
  • 1 Move the gear shift into the desired gear. Look at the gear labels and the arrow, or other indicator, to see if the gear shift indicator lines up with the selected gear.
  • 2 Move the gear lever to another gear and look to see if the indicator lines up with the selected gear. Misalignment of the arrow will tell you if there is a problem. Moving the gear shift to "neutral" but having the indicator show the transmission is in "drive" tells you the gear shift indicator is not working properly.
  • 3 Try each gear position to determine how much misalignment is in the indicator. Slide under the car and check for a loose gear shift cable. Check all the gear shift cable connections to ensure they are all tight and are not missing. Tighten any loose gear shift cable clamps or bolts. Replace the gear shift cable if you find that this is causing the misalignment with the gear shift indicator.

So we took our 2003 Chevy S-10 truck into a local shop to get new seals as we had transmission fluid leaking. The truck was working properly when we took it in. When we went to pick it up they told us that...


a transmission that has wear tends to leak and a fluid change may not help instead make matters worst and the loud sound is bad news yes the transmission build pressure and blew it it's not common to blow fusses that unless is the fuse for the transmission or they disturbed any wire harness.

Hello, I own a 93 toyota forerunner, 4*4, v6, automatic. Transmission was only shifting at very high rpms. Replaced trans with another out of identical vehicle, transmission will not shift, disconnected...


The transmission is controlled by the Transmission Control Unit (TCU).

Throttle position, rpm, and speed are input parameters to the TCU. The TCU has a default set of shift patterns. These shift patterns change over time based on your specific vehicle setup and driving habbits.

The shift patterns are only slightly affected by driving habbits over many driving cycles. But, changing the relationship between the throttle position and the actual speed being reported by the speed sensor can have an immediate effect on shift patterns.

While your speedo may now be correct, the realtionship between rpm and thottle position has not been corrected. That would take a gear change in the differentials.

The TCU can be reset to an inital learn base line. When this is done, the TCU will instantly learn the dynamics of your setup.

Any shop with an advanced ODB scan tool can reset the the TCU. The dealer or a transmission shop would be preferable.

You really should change your differential gears as opposed to resetting the TCU
