I own a 91 940t. I've embarked on the challange of "virtually" flushing the tranny. I understand that the tranny hold 7.5 liters. What I've done is drain whats in the pan. I've done this four times now, and with great sucess. The fluid a bright red and is clean. My only concern is now it seems that shifting from first to second is weird now. It feels like the shift is very very crisp not so much harsh but just sharp. All the other gears are super smooth and fine. Is this normal shifting for the aw71??
