The reverse is very weak and will only reverse when the car is on an level ground with a bit of decline, if there is any elevation on the surface it will not reverse. It was changing gears normally but now I have noticed that its not changing and the RPm goes up to 40 and the car has no power so I have to drive very slow, it only stays in one gear when I am driving and does not change. I added Lucas transmission fix it worked for awhile but now does not seem to help, Any advise or help would be appreciated
