I'm no mechanic but....

hi, i have a vy ss crewman (auto) i think theres a prob with my gear box but dont no what it is when i take off it feels like it gets stuck in first gear and keeps reving until i take my foot off acelerator then it changes to 2nd gear after that its fine just the change between 2nd and first, i tried driving it through the gears to c what happend first felt fine clicked it to 2nd felt fine but then when i alccelerated it felt like it drops back to first again and revs hard, am i up for a new gear box maybe?

Hey Korny,
I'm no mechanic, but my rough understanding of automatic transmissions would seem to indicate a couple of things that you could try yourself first:

1. Check your ATF level as per the owner's manual, possibly hot, after first running it manually through each gear, then back into Park. If low, top-up.
2. Check the quality of your ATF, if dirty looking or smelling, change.
3. Could also remove the oil pan & clean-out any friction material residue, then re-fill with new ATF.
4. If you're a little more adventurous, you could also remove the valve body (assuming it's a straight-forward bolt-up job) and clean it out. Gotta be careful here, 'cause there could be a whole mess of springs & ball-valves just waiting to catch you out. Best get a service manual & read it carefully first.

Also, I'm not sure about how the engine is linked to the kick-down control on your car, but that may be something worth investigating. Maybe it's a vacuum-servo arrangement that's got a sticky or even loose diaphram-actuator or something of the like.

Again, mate I am NOT a mechanic, so please INVESTIGATE the simple stuff first.

Cheers

Is it a major job to replace chip with a new one.

Yeah, I know you're right Davey, but stupidly I bought the car from a dealer almost 2 hrs drive from me, and I guess to be honest, I really do want to know as much about my car as possible, so I'm not adverse to trying simple things myself.

You do know you can take it to any Holden dealer right?

...Fair enough about wanting to try things yourself first...

i am having problems with my vs commodores it has ad a rough idle for a while now and now someytimes when sitting at the lights it will completly die out but it was starting straight away.
it would also die out and lose all power when going along but wouldnt completly die out just like cut out adn cut back in it is an auto v6 vs commodore.
and jsut recently the car wont start sometimes and takes a bit of stuffing around to start it and the problem with conking out still occours. any help ould be greatly appreiciated
i have taken it to a mechainc and he said his best bet was the crank angl sensor but he wasnt sure and i have done the crank angle sensor in the last 2 months. i have also put in a new dfi module and coil packs. i have replaced the fuel filter just recently and there wasnt anyhting major in that either jsut a problem that isnt always there and cant get fixed

it is booked in for wednesday but as i rely on the car any info would be great

cheers brad

if its any of these parts it should log a code indicating where to start looking

I can`t find the vac line on the reg, there`s a fuel in and out but no vac line, is it surposed to B at the back?
HERES A PIC

the pic you have is a damper to stop fuel line pulsation, the reg is on the fuel rail

Hey There,

Just recently got a VS Calais Acclaim 3.8lt. All good but noticed the temp gauge slow to respond and suddenly jumps to its level, now petrol gauge and temp gauge dont budge at all. Your thoughts appreciated.

common fault would be a poor solder joint in the dash, fix it or get another dash

Hey doctor bob, not sure if you know much about VE yet but are you able to point out/find out the position of the bluetooth module and where it plugs into.

Here is a pic.



about ^ here there is a plug that doesn't connect to anything. It has about 12 pins do we need an extension harness or is there no plug there at all?

Sorry for the quality of the pic. Any help would be much appreciated.

if the car didnt come from the factory with BT you need to fir the complete kit, the wiring isnt there, you are in the right area but theres nothing there.

 

[Doctor Bob]

yer i checked the codes and came up with old ones lke the crak angle sensor and that and i also have figured out why the car wouldnt start whihc was the loom gogin to the dfi module which i have previously had problems with but i jsut blew it out and pluged it back in and it was working sweet as but the car still stalls and it still cuts out and kicks back in while going along any help would be great cheers

get the car too someone who knows what they are doing, it sounds like you have a wiring problem that needs professional help

 

[Doctor Bob]

Hi doctor bob,

i have a VY Clubsport, and for some reason the automatic sensor works sometimes, then most of the time the lights stay on all the time, even in the middle of the day. i have tried to turn it back in the options in the dash to come on late. but they still stay on all the time, your ideas?

Thanks alot

it may be a faulty sensor or BCM, whatever it needs to be checked with a tech2 to see whats going on.
