GEARS not engaging

MatP38 · Nov 9, 2017

Hi ,
I just incountered another issue with the truck (1998 p38 petrol 4.6) . It wouldn't start (immobilised error ) so I keyed in the code to the drivers door and she fired up in park but when I tried to put it into drive it would not enguage , then when I tried to put it back in park it gives a plastic gear grinding sound and will not go into park . Any ideas ?

if it grinds trying to put it in to park ,youve either got a transfer box in neutral or 2 bust diffs etc

Not familiar with P38 but this popped up at the end of your vid....

There's a motor to shift the gearbox between high and low ratio. Are all connections to that good? Any messages on the dash? You can put a fuse in one of the slots to force the transfer box into neutral. From memory might be fuse 11 in the ones under the driver's seat? Try putting a fuse in that and see what happens (car shouldn't go anywhere!).

I think @jamesmartin is probably the best diagnosis so far.
Can't remember on these if there is a propshaft between the output of the gearbox and the transfer case or if the transfer case is bolted directly to the gearbox. If it's a propshaft, you'll be able to see it turning in D if the transfer is in neutral.

Directly bolted to the gearbox.

Bugger.
Is there any way to tell on the transfer box whether it's in hi lo or neutral?

You can take the range selector motor off and manually turn the triangular shaft.

I guess that is his first port of call then!

Yes, if JamesMartin speaks you'd do well to listen. It is just a case of homing in on the problem now.

if it grates when going into park your either moving or theres a break in the drive train to the wheels allowing g/box to turn,neutral t /box is one of the common causes,knowledge is more important usually
