Well is this bad, like going from 1st to 2nd and o/d off d and then to d is that gonna make my transmission drop out?

 

no it just doesnt make sense, your not going any faster if you would leave yor car in D jus leave it in D and let the tranny do the shifting. thats y its auto not stick

 

i've been manually shifting my autos for 2 years now. i've put down a good 50k on the tranny and it still holding strong. the reason i manually shift my auto is cuz i have more control over my car at varies speed. thus putting into the right gear helps me to stay in my powerband...also prevents me from fallin asleep while driving.
