well first you have to shift it into the reverse gear. then you look over your shoulder (right if you're backing out right left if you're backing out left) and very, very gently tap the gas pedal. Most of the time the vehicle will back itself out without the gas pedal but if it isn't moving then gently tap the gas.
that sounds like your transsion you should have it looked at although you can drive it with out reverse for quite a while
10 mph
it will drive but when in reverse it wont move
Drive...
Carefully.
As fast as you can drive it in reverse.
if the generated emf in motor is greater than supply voltage means the drive will goes to reverse
No
The shifting in your 95 Dimante should work properly. If it is not, there is probably a gear out and you will need some transmission work done.
because your car has some problems i think you should buy another one :)
my 2000 gose in reverse but not drive
Because reverse is a lower ratio gear than drive and puts less load on the engine.
