Hey Guys

Hoping someone can assist me and shed some light on a issue before i go ripping the transmission out.

I have a Zafira here Auto only done 90,000k and im having a problem with the transmission.

When i start the car every day she runs beautifully very smooth and no weird sounds however once the car heats up fully the transmission starts to play up.When i come to a complete stop and go to take of the car seems to hesitate and shutter a little then all of a sudden she jumps and races off. "almost feels like holding the breaks while reeving and then releasing them"

No i have noticed is i press the sports mode button on top of the shifter is increases the problem but if i press the the snowflake button the problem go's away but of coarse it is very slow then on take off.

I have also noticed if i put the shifter in first gear on take of it also does not have the problem. The problem only happens when in 2nd, or 3rd or drive.

Now for the really weird part. If i turn the car off when it is at normal running temperature and put it in park and try to start it it will not start until it cools a little. The motor will not even try to turn over as if it is still in drive?? and yes i have eliminated the starter motor

I have change the oil and replaced it with genuine fully synthetic oil but it made no difference.

Im hoping someone out there has some great advice on AUTO's and can explain this for me
