My z is starting to lunge forward every time i start the car. I have it in park and when i start it with or without the brake on the car literally moves forward an inch or two. shifts fine through the gears otherwise.

Should i change the fluid and maybe even pay for a power flush immediatly? Is it serious? anyone ever heard of this?

Thanks

 

Start the car and place it in neutral. Does the car move forward (try using the accelerator a little)? If it does its most likely the forward clutches that have welded themselves togethar.

 

If your speaking of a slight lung it may just be parasitic friction or inertial move. Unless you dont have reverse I would say its not the forward frictions welded.
Some forward surge is normal even in neutral and park when the engine revs. I see alot of people ask about this.
