Mk2 2.8 speedo/gearbox fault

[Br00n1e]

would think the speed sensor in the box sends signal to the speedo head but, I may be wrong

[dragon]

can anyone tell me if this is the sensor i should be looking at.
this is at the passenger side above the adjusters for the torsion bar on the n/s
the sensor with red wiring plug

the signal is sent from the gearbox end first. the switch daz could be it take it out if its magnetic thats the one if its not magnetic then could probably be the reverse light switch.

reading about the internet mate i think that its a strong possability that your KMH to MPH converter could be on the blink, everyone is quoteing very similar symptoms as yours.

Not strictly true mate, when i bought my GDI the speedo needle had been pushed to far onto the shaft and was sticking and when id did so the gear bog would not change gear when it was supposed to because the box did not know what speed it was doing, there wasnt an KMH to MPH converter fitted at the time but i have since fitted one, unfortunatly the one i have fitted is causing the speedo to read 10 MPH fast this causes a problem when i am driving at 30 MPH because the speedo is reading 40 MPH so the gearbox dosnt drop down a gear like it is supposed to this then over gears the engine slightly.

The gearbox does take a prompt off the speedo to know what gear it should be in the sensor we are talking about is measuring the final drive RPM.

just worrie about removeing sensors and them breaking or something its hard enough running a truck when ya in full time work but been out of work sucks and running the paj is a nightmare.

If you cant afford to go - how about getting a lift and sitting in with someone who hasnt had the pleasure of Kirton matey.

..................and it may not cost as much as you think - finger crossed matey

[dragon]

would be a good idea but wouldnt want to rub tanya n damons noses in it as they look forward to going to kirton .
was supposed to be takeing my daughter sophie too and our babysitter amy
for some reason it only did it once yesterday and didnt do it again .
going to take it on a run as it seems to do it when it gets hot.

Any help ?

(Its for a 3 litre cos the US never had diesels)

[dragon]

am i right in saying that where the speedo cable is housed at the gearbox end on cable type models the speed sensor would be fitted in the same place on electronic models as i have found a sensor as described by j.s.autos in that location as the pic i posted earlier in this thread

[TinyTim]

Not a 100% sure mate

I have the info as to what sensors - but not where they are exactly.

I'll have another look at the CDs

[TinyTim]

Ah ha !   

(This from 2001 but basic locations don't tend to change much)

[craig]

Did you have an luck with getting it fixed?

[dragon]

no i think its got to be the speedo head thats naffed so roll on thursday when it goes in the garage more cost AGAIN

[joker777]

two very handy diagrams there tim i realy would like a copy of that cd .

[TinyTim]

Ah - that's from another CD mate

But I'll see what I can do when I get this puter sorted cos it won't write anything atm   

Got another drive on the way
