gear selection dial MY13 D4

[kmdisco]

Hi All
I have a MY 13 D4 started the truck up this morning gear dial came up and in a matter of seconds it went back down and then in about 20 to 30 seconds the gear selection dial came up and I was able to select reserve gear. and drove off.
Could anyone let me know if this is a problem or is this normal with the D4 ?.
It appears to happen when doing a cold start


regards Kev..

Havent heard of this on a D4,it could be a transmission protection for the cold start.
My CAT grader,and the previous one wont allow gear selection on a cold start,it just shows a dotted line for both forward and reverse gear to select.Only on VERY cold mornings,usually less than 1min,up to 2min max.Yes I do warm the machine before operating,just to get the heater working

Here you go Kev .... from Disco3 in the UK. Yours could be suffering from this.

DISCO3.CO.UK - View topic - Rotary gear selector won't stay up when cold.

A customer may report that the Transmission Control Switch (Rotary selector) intermittently fails to rise when the Start/ stop ignition button is pressed or may rise and fall immediately, particularly where ambient temperatures are less than 4 degrees C

The motor within the Transmission Selector assembly may be at the lower end of the specification preventing it from rising within the required time span.

The fix is to replace Transmission Control Switch.

Cheers,
Scott

Thanks Scott (LRD 414)
The Disco has only 11,500 k up now. I think I will keep a record over the next couple of weeks and then contact the Brisbane or gold coast dealer
and see what they have to say or do.


Thanks for your reply Andrew I don't think the little blue pill with help
with my D 4 problem
Thanks again for your replies

So when you have the gear stick,one less thing to go wrong

I would say that we don't have a gear stick, so one less thing to go wrong
