James, paperclip the engine - the engine can ask the gearbox to limp (and the g/box can ask engine to limp).

Before you did the top end, I bet you barely drove it much due to its issues.  Possibly and existing problem only showing up now, and unrelated to your work...

Sounds like sound advice Jaime

I'm just going to drag Markie downstairs with a paperclip in one hand and a beer in the other

I know nothing can be taken for granted, however if the engine was asking the box to limp, wouldn't I get an EML?

BTW.. we changed the gearbox ECU tonight, made no difference. so the old one is back on there.

Codes are on their way, cheers mate

Is that gearbox selector switch all nice and clean....

Is that gearbox selector switch all nice and clean....

Markie's response was "no, it's dirty, oily and sh!tty!

[Marks DTM Calib]

First job then....

[JamesV6CDX]

Cool, I'll do it tomorrow.

How best to tackle it - remove it from the car?

What's the best way to clean it all up, do I need to take it apart?

[JamesV6CDX]

Right, going out with a paperclip now

Back with results in 10 mins!

[JamesV6CDX]

Engine Paperclip Fault codes are as follows:

144
145
31

[JamesV6CDX]

31 - crank sensor - normal with engine not running
144/145 - immobisor crap, which I know about...

so no codes that could be causing the gbox to limp

I will clean the selector switch tomorrow and see if that helps, and make sure that connector is still ok

Please help, insurance is swapped over now, I need wheels

......
It wasn't doing this before the top-end rebuild... but I cannot see anything wrong, everything is in place, I've checked all connectors are home, incl the ECU one ......

When I did the cam belt on my car I forgot to reconnect the throttle position whatsit and the gearbox went into limp mode then.

[Marks DTM Calib]

When doing the selector switch.....do a maintenance guide....

[JamesV6CDX]

When doing the selector switch.....do a maintenance guide....

I would if I knew how

I can see how the switch comes, off, but must I follow any particular procedure for removal, or have the selector in any particular gear?

I've never taken one apart before

James
When I removed mine for cleaning I had the box in neutral. Be careful about removing and replacing the switch on the selector shaft as you dont want to damage the seal in the switch case.  Lie it flat on the bench when separating the halves and you shouldn't have any problems with dismantling

[JamesV6CDX]

Righto... believe it or not I'm not 100% confident about this job... but here goes!!!

If this doesn't work, I may have to resort to Tech2

Jaime - does Tech2 read codes that have been "stored" in the gearbox ECU - indeed does the gearbox ECU store codes at all? Or.. does the fault need to be present for diagnosis?

That won't be a problem... it's in limp mode 99% of the time!!!

[JamesV6CDX]

it's off... .just fannying around trying to find a male torx to fit the bolts to take it apart

what's best to clean it with?

[Marks DTM Calib]

Well....start with soap and water....idealy you would use contact cleaner.....carb cleaner might well work as it wont affect the pcb tracks or contacts....
