Thread: Auto No drive

Another auto intermitent fault that is occuring.
It is an 02 Disco TD5 with 250K on the clock.
Ocassionally when you select D or R the vehicle will not go, just revs., as if you are in Neutral. Sometimes if you select 3 or 2 or 1 it will go, other times you select R first and it works.
Sometimes I will switch the engine off, wait a minute and restart and it will select gear and go. Sometimes I just wait a few minutes and it will work. This occurs when the vehicle is cold, and when warm. All the gear selector lights work correctly on the dash, and on the console. I do not get the M&S flashing lights which makes me think it is not the inhibitor switch.
Once it decides to work it shifts properly at speed and appears to be working / operating correctly.
I have tried to fiddle with the selector adjustment at the transmission end but does not seem to be much room for adjustment. Is there an adjustment point at the console end?
I will check underneath tonight and see if the wiring loom to the transmission is okay. Any ohter suggestions?

Checked the fluid level lastnight and it was full. The colour was off a bit, but not too bad, and smelled okay. Checked my records and is about 7K overdue for a service. Will give it a good service with filter change and see what happens.
