Hi, If I take it out will gear box oil pour out or is there a nack to changing without spilling?, seems to be on bottom most of gearbox. Thanks

Can the 1st gear switch be taken out with out emptying the gear box of oil

It seems the source of the amber hdc light while driving was the reverse and 1st gear switch were on at the same time

Did u get this sorted I had the same problem, seems it was plugged into bottom thermostat sensor on the right of the engine.

Sorry I was seeing the pink on temperature, that's what they are with the tracers. Everything seems to be sorted anyway just that the 1st gear switch is duff

Just shorted the first gear switch cable with paper clip and hdc stays solid when engaged which from what I can gather is correct and throws amber when in reverse because 1st gear switch is engaged with reverse switch which was the problem I was having in first place .... New switch it is so, I...

And thanks very much for data, it's made sense of it

Ye baffled my head all day..... What it seems to be is that I have a old engine with the two coolant sensors, one for gauge and one for ecu But I have a new wiring loom with just one sensor connect for coolant temp shown here with two pink lines So who ever changed engine put the first gear...

How would I test it with out taken it out ,looks like it will flood the place with gearbox oil?

Ye flashes green and only solid in reverse. Flashes every other gear.

Sorry

Ye sorry that's me . My bad Seems I still havnt got it sorted hdc will on stay solid if in reverse, flashes in every other gear,but warning is gone in normal driving. Does that mean 1st gear switch is shot

I pulled the connection of the blue sensor, what is that one? I know the other one is coolant sensor

Was wrecking my brain all day couldn't under stand why loom wasn't there

I know the front sensor is coolant temp but what is the bottom one that I took the connection from?

That's wher I got the 1st gear switch wire from. What have I taken from??

I think Iv sorted it but I don't know what iv done if I'm honest. Took and feed from thermostatic monitor switch that was right color combo for 1st gear switch, had the right connection and length of loom to reach switch and now the waring light gone from dash and hdc works

OK this is gonna sound really strange. But got a company to check a k series gearbox and the color or wires to 1st gear switch. He told me it was green with black cheese and black. So check in the loom closest and that color combo connection went to the bottom or thermostat monitoring housing on...

First gear switch is giving me a hdc waring light on dash. The switch is in/on gearbox along with reverse switch There is no wiring to the first gear switch, it's none exsitant The question is: if I was to make a new loom, where would it go back too? Or can anyone tell me what color the wires...

Hi lads, Need some wiring info, have a hdc light on that seems to be linked to first gear switch that is in situ but no wiring loom, have open the loom whole way back to ecm or ecu under black cover and can't see any cut or spare wires. If I disconnect reverse switch veering works as should...
