hi DAN,
Just a 2 days back My automatic gear shifter went into problems....
this is how it happened:
When i drive my 05 saab 9-5 for a while the gear goes hard and i can even feel a big jerk (like someone just hit me) changing gears ( even when i change P,D,R). I just did trans flush with ATF 3309 and it would go but it still feels the same. the mechanic said to rebiuld the trans. Is it worth it. He is charging me $2500. this is my only car and it will be dificult for me go to work without this. I want some solutions immediately to fix it before somethings really bad happens.
