yesterday i was given the number of an ex vauxhall mechanic and told hes yer man.ive just spoken to him and explained how my box wont select 1st or go throuigh the gears when in d but i can manually select all the gears and he said is yer eml on(yes) and he said the last one he had like that was caused by the crank sensor ive no reason to doubt him and was wondering if anyone else has had thisand is it an easy job to try another

errr he's talking crap, crank sensor (code 19 if you paperclip *edited, you can't paperclip) will cause the engine to stall and then eventually die, not allowing it to start. It would not affect gear shifts, if it did, would put it in limp mode (rev limit 4k)

I would suggest checking the ATF fluid level (should be at the drain plug on a level surface with the engine running) also cleaning the selector switch on the gearbox, thats your most likey causes

ive still got full revs and oil was spot on when i changed box on friday,all the lights correspond with selection and the switch i checked with the welding rod and the 2 slots lined up right in neutral just in d all ive got is 3rd.whats best way to clean switch give it a blast with brake cleaner or alike or do i have to remove it

Its fairly easy to remove, some contact cleaner would do the job.

Might be worth investing in a cheapo tech2 off eBay (£30) if you have a laptop

a chap called rustym95 has offered to put his "My Naff Code Reader" on it but its just meeting up with him at a time we both can sort out

I have seen a dodgy crank sensor signal put an autobox into limp. (Short in a poor pro LPG install)

The signal is used so the gearbox knows what RPM the engine is doing.

Same signal used for rev counter as well.

what i dont understand is how when i put it in d it give me a forward gear be it 3rd why is it not working as it should and selecting 1st then 2nd and so on

I'd give that selector switch a clean! Even if the crank sensor was failing, you would still get all gears, but limited to 4k rpm

Just a thought, could it be an issue with the winter button wiring.

Just trying to help.

That would cause the similar problems, ie always pull off in 3rd when in D.

But it if you put the box in 1st that should overide it, and pull off in 1st.

yeh when i put it in 1st it selects first,ive no sport button and havent checked winter mode.the box i took out had no 1st gear at all was told it had split a drum and that box wouldnt drive when cold unless i pushed the winter mode button

Check the snowflake button on the passenger side of the gear selector

[sexydaz]

if that had a fault it would select 3rd,when i manually select 1st it would over ride it then put it in d it would think winter mode again yes a possibility.i wonder if i took a wire off it would cancel it out or would it put a break in the circuit

My sons 3 litre facelift, the snowflake button broke and was jammed in.  Removing the broken bits of plastic jamming it in solved the 3rd gear/manual select liftoff prob.  Would also be looking at the selector on the side of the gearbox, as said.
