Hi,

It may help if you state what engine you have.

Cheers

Sorry, Its a 300 tdi 1997 manual

You say it selects 3rd and reverse in Low but not Hi,

Does it drive in LOW range in 3rd and reverse?

Cheers

 

[CellumH]

Yeah so it selects and drivable in every gear in low but in high its as if the gear knob doesnt push into the gate?

I'd say change the oil and filter before anything else if you know it's old... a good practice is to change the oil once, drive it for half an hour to make it change through all gears many times then change it again with the filter, then you'll have about 75% renewed oil in it, a simple oil change will be max 50% new oil

EDIT: disregard this post i've had a mental hiccup

Filter? on a manual?

I am confused, as to how the ALL the gears in the gear box can be selected in LOW range but not in HI Range.

Cheers

 

[CellumH]

Yeah im abit confused aswell, not sure how that could happen not good though!

Thanks

 

[CellumH]

Could the transfer box be knackered or it that not really symptoms?
Thanks

 

[neilly]

OK,

As I suspect you are going to need it, Download the Rave workshop manual.

[CellumH]

Thanks dude sure that will come in handy!!

 

[CellumH]

Which one is it i need? Disc 1? thanks

 

[neilly]

It lists the vehicles it includes on each.
So as you have a discovery1 I would think Disc 3 would be good.

Cheers

 

[CellumH]

I'm a bit confused about that too. The gearbox and transfer box are to all intents and purposes two separate units. So I cant see how one can affect the other in this manner, unless there's something going on with a loose or worn component near the two selector levers in the transmission tunnel where the levers live.

 

[CellumH]

I literally dont have a clue where im looking mate so cant check? :/
Thanks

 

[Speckydude]

Transfer lever rods a bit goosed / loose / bent ?
