I had a 1991 Infiniti that wouldn't go into overdrive on really cold days until it was warmed up. It seemed really really strange to me, but the dealer told me it was normal behavior. I'm not sure I believe it to this day.
Could there be vacuum leaks? Maybe with extra startup air the vacuum is so low that the trans thinks it is under full throttle? (I know the later d-jet injection has an Aux Air Valve that closes when the car warms up.).
My dream car is a classic sporty five speed (stick+overdrive) convertible that seats five. If, you want 70's-80's Mercedes tuner wheels, let me know.
