Autobox speed sensor -- help please

That's brilliant.

I'm going to get it back from the auto box people before they remove the box ...... and take it back to the workshop which pulled the box last week.

Surely they pulled the box and yanked a cable or three ...... just like you said.

Wife says that the mechanics were looking very sheepish when we collected the car ..... she notice these things!

Happy days!

I've made a note to go look tomorrow, will report back.

Thanks -- I'll be checking e mail on the phone.

Wait - you mean below he cubby box between the front seats?

Yes, on 1999 and on models the XYZ switch also feeds through C0988 and on pre 1999 models partially through C560 and through (One wire) C559. All connectors are to be found in same area. Theory being they have dropped the box without disconnecting plugs from it and pulled the cables.

Not sure you can get at it from the cubby box, I can look at my scrapper tomorrow if it will help, I have the whole centre console out.

You have to remove the centre console Keith i think. Connectors are below area where cuddy box sits.

Centre console is already out on the scrapper It is a disel though so I hope the loom will be similar. Off to look shortly

Very similar, on later models 1999 on everything runs through C0988 on earlier versions two connectors used C560 and C559. Only difference petrol to diesel are pin outs to ECU.

OK, there are 3 connectors, a large white, a large brown and a 2 pin power connector on my MY96 diesel, all should be accessible with the cubby box removed, the remainder of the gearbox loom continues over the transfer box and down to the transfer box shift motor and position sensor which would also be worth checking. The connector into the box itself is much further forward on the side of the gearbox near the XYZ switch and is not easily accessible.
If the gearbox was lowered rather than just pulled back, it would not take a lot to either part a connector or pull a wire out of a crimp. The gearbox loom passed through a large rubber grommet above the rear of the transfer box, if that has popped out it would tend to confirm that the loom has been subject to strain.

Many thanks -- I will use this ammunition for a talk with the workshop.

I'll be back to pester you on Sunday.

If it helps, I could photograph the area.
I suspect, the dropped the front of the box which would have stretched the loom.

Can you see which cable comes from the speed sensor at the back of the box?

That would be useful to see ... how it comes through the transmission tunnel and off the the ecu.

Cheers.

A photo would maybe helpful to him Keith the component location views in RAVE are pretty crap magnified.

Well, here I am back from the auto box place empty handed.

I went to take it for a test drive to find a bad misfire ......

What on earth could they have done to the coils?

Plug leads are new, plugs also (new means 6 months or so). Engine is new.

No misfire evident before, the engine is very sweet ....

Really trying to stay calm here - they fix one thing and break something else.

They say sorry and that they will fix it ...

I'm going to sit in a dark room for a while

If they tilted the engine to drop the gearbox, maybe they whacked a coil. I suppose the plug leads are on to the correct cylinders?

Thought I'd close this one.

Prepare for a good laugh ... or tears!

Auto box man checked all wiring around the gearbox, especially the one connecting to the speed sensor at the back. All OK.

Then he removed the box and found an internal problem and overhauled the entire thing .... my wallet is somewhat lighter now but the wife is still speaking to me.

Somehow, a coil pack was damaged, so he replaced it at no charge .... showed me the old one - no sign of physical damage at all.

All well now.

Thanks for all the support.

Sorry, don't believe it. If there was no dash indication of the gear lever position there was an electrical problem. They are just covering their arse and taking your cash.

I am also of the same opinion. Think someone has been stiffed.

Yes, maybe - I didn't go to see if they actually removed the box and overhauled it. They said they replaced or serviced the pump, clutches etc ...

If I dwell too much on it it will gnaw away at me!

On - on .... and looking forward to Europe in the summer!

The pump nor the clutches would cause your problem. Nor would they show on diag as a fault. Your problem was electrical no electrics in pump or clutches.
