Line pressure problem in trans due to low fluid, bad pump etc. Check fluid first.
it will drive but when in reverse it wont move
== ==
A car that won't move when in reverse could indicate a problem with the transmission. It could also indicate a problem in the gear selector.
crankshaft
bad transmission
Check transmission fluid level.
If you have an automatic transmission, it probably has a forward clutch/band problem.
No, the odometer does not move when a car is in reverse.
The purpose of an accelerator is the car is to give the engine gas so the car will move.
Yes you need to get a new transmission, because somehow you burnt out your reverse so it wont move in reverse. So you will probably have to get a new one. A cheap one is roughly $2000 give or take $100.
Check transmission fluid level Perhaps needs transmission rebuild
parking brake cable may be sticking.
