When driving my 200 Tdi DiscoveryRange Rover the gearstick has suddenly become very vague and is flapping side to side. Why?
Inside the aluminium top cover of the gearbox, which is secured by two large Phillips head screws, you will find two large springs which rest on a L shape steel plate which give your 3rd/4th bias gate position. This L shaped plate is very prone to cracking off where it is bent which will result in you losing the 3rd/4th rest position when in neutral and thus the shifts will become vague. This plate is inexpensive and can be changed with gearbox in situ.The part number of this Bias plate is FRC9340.
