probably something wrong with the transmission like a gear fault or a transmission glitch or overheat. Take it to a repair shop or do some test maitanenence yourself.
could be bad mounts on either the tranny or engine?
Are you sure it is the transmission that is clunking? It could be the u-joints on the drive shaft that are making the noise. When the u-joints on the drive shaft are bad, there is an audble clunk when you accelerate and when slowing down (basically the same motions you go through when shifting gears).
YOU WILL FEEL A CLUNK WHEN THE VEHICLE IS PLACED IIN REVERSE OR DRIVE AND IS ACCELERATED WITH THE BRAKES DEPRESSED
sounds like transmission problems( not moving in drive) and u-joint problems(pop or clunk
transmission is gone.
Get new transmission
The transmission
bad transmission
An electric drive motor which can propel you like a transmission is very close to silent in comparison. To go in reverse just reverse the polarity.
what is the problem when the car will not go in drive or reverse? and the transmission fluid is still full
You are probably low on transmission fluids
it could possible be the U-Joint which is a cheap and easy fix. it's connected to your drive shaft.
