I own a 1990 Jaguar XJ6 Vanden Plas Majestic with an automatic transmission. I just replaced the the transmission (shifting) cable as the transmission was not staying in gear. Replacing the shifting cable solved one problem as the car is now staying in gear. However, now it will not shift properly through the gears. When I start from a dead stop and put the car in "drive" it does not up-shift. It feels like it is starting in a low-default (2nd?) gear. As I increase the speed the car does not down shift through the gears, it feels like it is just staying in the same gear I started out in...Thus, as a result the RPMs climb very fast and at around 50mph are at almost 3000rpm. The transmission fluid is full and there does not appear to be any leaks. Could this possibly be something electronic (as in a bad sensor?) or is this more likely to be something internal in the transmission asselmbly? fyi, the transmission warning light on the dash is lit up. Any advice you could give me would be very appreciated. Thanks, John
