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 :y
-
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

cheers tunnie

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
-
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. :)
-
im gonna clean mi switch check all mi plugs to box check oil again now ive done a few miles and look at the winter button,folk keep mentioning selector so ive got my hopes on that. cheers guys ;)
-
well i cleaned my switch today and nicht,nato,nothing its still the sameim a tad cheesed off nah :(
-
have you checked the round blue plug by the battery tray, there are 3 plugs side by side, the blue one is g/box connections :y
-
i havent no,thanks im goin for wife in 5 mins il have a quick look cheers :y
-
dont help being dark but how does that plug come apart

AFAIK crank sensor is the one on the engine's crank, if is NOT working, your engine will NOT start, if it is not working correctly your engine will work VERY badly if at all...
So, I would not think that crank sensor will cause ANY problems with gearbox...
ATF level and worn gearbox clutches may cause such problems, I would check ATF first (much cheaper)...
-
it was all new oil on friday,ive been told today ive a fault in mi wiring
-
when i first got my mig i had g/box problem [diplayed on the mid] , mine turned out to be the g/box ecu but apparently that is a rarety, double check your switch & multi plugs on the g/box itself as it sounds like the g/box isnt talking to the ecu.
-
Firstly, the 'expert' vx Vauxhall bloke is obviously an idiot.
Secondly, **any** engine related code can stick box in limp.
Get a code reader on both the engine, the gearbox, and the ABS unit, and see whats what. This MUST be done by SOMEBODY WHO KNOWS WHAT THEY ARE DOING!!!
-
a chap brought some codes up on it and he translated them to if i can remember correctly (can svs requirements,maf sensor signal weak,mixture lean,torque control errors of expensive components)only code i remember is p0100,he reckons theres a fault in wiring,expensive component could be ecu,after cancelling codes when i chose a gear the gearbox light came on,after a few miles that went out and eml came back on

Might be worth a trip to Nottingham, and get someone with a tech2 and knows what they are doing to go through it.

aye im on the verge of pm,ing mark dtm

For the modest cost in fuel, and tech2 fee, its worth it.

sorry to butt in on the thread, but have read on other threads about having the tech 2 plugged in and sorting the gearchanges out on a auto box ?????? how do you know if it has allready been done ????

You can't, but its very unlikey its been done. If you have that 'surge' around 50mph, then its not been done. Its the down shifts which become super smooth after the update

pass tunnie about the surge, normally if i am giving it heavy right foot it is in sports mode and the pedal pushed down to the headlights :o so not really noticed it

Its worth the upgrade, drop TB a PM :y

cheers tunnie i will do, just gotta find the time and cash (misses scenic the cat packed up and was not covered on warranty as its a wear and tear part so aruing with them and trying to get a contribution towards new one and labour charges)

i know but she loved it and was better than the 07 plate focus she had (was a piece of sh1t)
