Replaced fuel tank pump, air filter, cleaned transmission circular cable connector with electrical contact cleaner (this cured erratic transmission behavior, smooth operation returned) but limp mode still occurs. I hear a lot of groaning and hissing, but this is from the Disco 3 TDV6, 2007, 90-something miles. OK, I've had the dreaded transmission fault, HDC system fault, parking brake fault and suspension lowered messages. In addition, the engine cuts out. I can still drive the car as the faults clear after a restart or two (apart from one time when I had to replace one of the brake light bulbs to get them to Rgjev. discobean.

Hi all, I have this dreaded problem, last time it was the brake switch, which I replaced a while back.

The gear selector lever may wobble back and forth, and without the tight fit, it may have difficulty fully engaging the gears. From a physics standpoint, the bushing helps focus the energy of the lever directly to engaging the gears. However, the basic process of resetting the gearbox on a Range Rover is as follows: 1) Press Start button, without turning on the engine. 2) Press the Accelerator to the floor for 15 seconds. 3) Hit the Start button again, turn off the power. 4) Stop holding Accelerator. 5) Wait for two minutes.
