I am having problems with the transmission in my car.
Hello, I am assuming your car has an automatic transmission. The first thing to check is the transmission level. If the level is low, it must be brought up to the correct level. If the level is good, then other things must be looked at. Does the shifter feel normal or does it feel loose? If it’s loose the cable may have to be disconnected from the transmission. If it feels normal and you don’t feel the transmission engage into gear, there might be an internal failure which would require a trip to a transmission shop.
