Hey guys i did a search and really didn't find what i need the answers to.
I want to know if it is bad to do the following and please tell me WHY it's bad etc if you can spare a minute. I've been keeping my car out of overdrive alot lately, i just turn it off and leave it off cause honestly i'd rather have the engine rev alittle more so i have better passing power on the highway doing like 65mph. Overdrive at that speed is like 1900rpms whereas 3rd gear is running like 2300rpms.
Is it bad to do this as far as the tranny is concerned..? In my search i found a guy that said the tranny fluid heats up more when the O/D is off and you're cruising on the highway in 3rd gear..? I know it wastes more gas and basically the engine is being used more, but does it really mess the tranny up staying in 3rd instead of O/D..?
The main reason i leave it out of o/d also is cause i do alot of flooring cause of azzholes on the highway and i know WOT into O/D is BAD. Also is it bad to take the car out of O/D when you're doing like 60mph to let the engine brake for you, or just to step it down so you're in 3rd..?
