to much tranny fluid

[ratz26]

i got a 2001 VT commodore and i just checked the tranny fluid cold while i was checking my oil and water and all that fun stuff.
i have a feeling there is way to much tranny fluid in it cause its right up to where the writting starts on a VT's dip stick .
what are the running symptoms of to much tranny fluid.
my revs are sitting at about 600 RPM and now and then the car will give a jerk and it will feel like the whole rear end of the car is lifting and the power train light comes on....is this connected ?

Was the engine running when you checked the trans fluid level? It needs to be running to do a level check just in case you don't already know. Up to 1cm over the hot fill level at cold check won't do any harm.

nah motor wasnt running just a quick cold check as i was passing by with the engine off and cold the fluid was at least 5 cm above the hot mark

ok just went for a drive to heat it all up and the tranny fluid is correct..
but are my revs to low sitting at 600 - 800 RPM?

revs are fine mate, trans fluid must be checked in 'P' to be accurate

idle is 700rpm +- 50

ok sweet thanks ....so what would be causing the other stuff? its like its surging when i have the brakes on u can actually feel the rear end lift up and the revs drop right down ..once the power train light came on and it wasn't till i kicked her into neutral and gave her a rev..

If you have the aircon/ climate on, in somecars if the battery isn't the best the automatic switching on and off of the air con can cause a voltage drop which will in turn cause a momentary drop in revs or a fluctuation. My calais does this as the battery is on it's last legs

oh ok ill get my battery checked ....i was going to get it checked cause it looks like its " weeping " from out under the screw caps ....i dunno if its just from the recent heat or not..

take it to a mechanics and get a scanner onto it and they'll be able to tell you why your powertrain light came on
