just after geting a 92 vp calais commodore v6 drove it from gold coast up the highway spedo not working says it has 214000 on the digital clock got off the motorway came to a roundabout had to accelrate but it woulndt shift up the gears had to go to 4 and 5000 revs there is a jerking when it changes to 2nd gear any help resolving these problems would be good..

shift kitted trans for the hard jerking

revving too high to change means u have to adjust your kickdown cable

i adjusted the kickdown cable its not jerking any more changing gears ok too but when i come to a stop the car tends to move forward not stay without acc i took it for a spin the oil level looks to be higer than it should be should i drain it back to the proper line it could be 4cm above the full mark

you have your throttle or kickdown cable to tight ..... is it revving higher than normal when you come to a halt

If the ECM is not seeing a speed sensor signal, the idle will be affected as the ECM has no way of knowing when the car is idling versus driving down the road. I would suggest fix the speed sensor problem and the idle problem will go away. The most likely problem, if you want to guess rather than diagnose it systematically, is the sensor itself, which is the black plastic cylinder with the electrical plug on it, located on the back of the transmission.

An overfilled auto trans. level can cause shift problems and long term will kill the trans. You haven't said how you are checking it but in Park, engine running is correct - it will appear overfull if you try to check it with the engine off.

The oil level will also vary with trans. temp. The correct way is to drive the car until the trans. reaches operating temp. first. As a guide, if you can't touch the dipstick end without burning your fingers, it's at operating temp.

If you do need to drain some oil out, undo the top hose to the auto oil cooler in the radiator at the line (as distinct from the radiator) end and direct it into a suitable container. (I find it easier to remove the engine cooling fan first - 4X 10mm head bolts and one electrical connector). To pump the oil out, have someone else start the car and signal that person to shut the engine off when desired. Watch the fingers around an operating engine and communicate well It's also a good idea to have some new replacement fluid available in case you remove more than is needed.

hey now replaced the speed sensor it was buggered holden quoted me 255for a new one got a secondhand for 30 first to second is still a bit jerky all the other gears are fine thats the old speed sensor fixed but there is more problems fill up the tank from red mark 50l then i noticed it leaking from the top of petrol tank . any way the next major thing is when the engine is running there a rattle in around the the belt and the teninsor jumps up and down a little the seller said that the water pump was changed and the teninsor as well any help on this would be great thanks ..
