Well check the fluid.It maybe low you have to have the car running when checking it.It low top it off and see what happens. change fluid and filter. filter gets clogged when debris settles and blocks fluid from transfer. if left alone it will take tranny out
A 97 Saturn that stays in forward gears could be one of two problems. Either the electronic transmission controls are stuck in forward, or the internal bands in the transmission have welded themselves together.
Either by pressing with your left foot on that pedal and releasing it, or it may release once the cars transmission is placed into either 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.
do you have all forward gears? if yes, you have broken reverse gear (one turning the spin into reverse) in the transmission, if you miss also some forward gears it shifts rough, tranny is to be rebuilt... either way it's expensive fix
The car might have an automatic cut off to either disengage the transmission or cut off the engine. Otherwise you will rip apart the transmission.
could be either transmission shift linkage not engaging reverse ( stops at neutral ) worn joint connectors sometimes cause this. or reverse clutches or gears bad inside transmission.
there is either an electrical or mechanical failure in the transmission
The reverse is "shot" on your transmission. You'll need to either rebuild/replace the transmission or get another vehicle.
check transmission fluid levels and condition of fluidreally does sound like you either got bad transmission or neutral lock out switch is faulty
Having it on "PARKING"
Yes, enzymes can catalyze both forward and reverse reactions by lowering the activation energy required for the reaction to occur in either direction.
I'd say you have a problem with either the linkage to the transmission, or the transmission itself.
