trans is slipping
If no forward or slipping forward suspect problem in the forward clutch and circuit. Reverse does not use the same applied components
your problem is the transmission. you need to replace the transmission
If you mean the transmission itself shifts forward, it is because the transmission is suspended, so when the transmission is put in reverse gear the momentum will push the transmission forward. Now, if the car pulls forward when put in reverse, this means there is a transmission problem. This may just indicate the shift linkages need adjustment, or that the transmission has a major problem and needs repairing. Take it to a shop and have it checked.
When a Mercedes C280 will not move in forward or reverse it is an indication that the transmission is going out or has already gone out in the car. This is true of all cars, not just a Mercedes.
13bn771g729 shuts off when put in reverse
Bring to a transmission shop
It's probably not a motor problem. What led up to the problem? Did it just appear or did someone work on the electrics and then the problem cropped up? Where do the sparks fly from? It may be a solenoid problem, but the symptoms reveal little.
Your arctic cat 580 will go in reverse and not forward because the reverse linkage is okay while the forward linkage is not.
If you have an automatic transmission, it probably has a forward clutch/band problem.
Check your relay under the dash. My 1991 JCB did the opposite and that is what the problem was.
has a full charge won't go forward or reverse
If Reverse works and Drive doesn't in a Safari Van, the problem is in the transmission. The belts for the forward gears are either stretched too much or broken.
