To repair a transmission overdrive shifting problem on a Mercury Villager, start by checking the transmission fluid level and condition, as low or dirty fluid can affect shifting. Inspect the throttle position sensor and vehicle speed sensor for proper function, since they are critical for overdrive operation. If those components are functioning correctly, consider examining the transmission control module for issues or performing a diagnostic scan to identify error codes. If the problem persists, it may require professional assessment or transmission rebuild.
changing the fluid on the transmission if it already has a problem might make the problem worse. you probably dont need a whole transmission. the one you have is fixable. it would be necessary to take the vehicle to your nearest transmission shop for further diagnosis to determine if the problem is internal or external. They might tell you that the transmission would have to be removed from the vehicle in order to determin the problem. if so, most shops offer to do this at a reasonable price.
You can detect a bad transmission using a diagnostic computer provided by the car's manufacturer or the car dealer. You can also detect this problem when the car fails to shift correctly or does not shift into a gear at all.
The first thing to do when the car won't shift correctly is to check the transmission fluid levels. If the fluid level is fine, there could be a problem with the throttle cable or with the transmission itself. Consulting with a mechanic is the best course of action.
When you have problem shifting gears, you transmission has a problem.
What type transmission and what problem?
Could be a problem with the overdrive function of the transmission.
If it is a transmission problem, the best thing you can do is have the transmission rebuilt. That will fix the problem and prevent any further damage to the transmission.
your problem is the transmission. you need to replace the transmission
If you mean dilemma as in 'a problem with no acceptable solutions' then yes, you are spelling it correctly.
Had the same problem and changed the Variable Speed Sensor and it solved the problem for me. I have a 1994 Accord LX sedan.
Depends on the transmission and year. 5 or 6 cylinder? What is the problem with the transmission?
