This talk about whether I regret getting an autmatin has me thinking...I frequently shift my automatic manually. ie: start from "1", rev to 6K, push up to "2", etc. I find it prevents it from shifting into the next get too soon on it's own. I do NOT do it when I slow down, just from standing starts (except w/ the OD button). Other than the obvious increase in fuel consumption from the higher RPM's is there antything detrimental to doing this? Does anyone else do this?

 

I know what you mean, I do it too. I know it's not good for the car, but I don't do it that often. However, I do leave the overdrive off when I'm driving below 60mphs. One thing I know for sure is that by doing that it does consume more gas than usual.

 

u can do it once in a while but dont make it a habbit. i do i too. dam i wish i had a 5 speed

I don't manually shift my auto, but I constantly hear that it's bad for the transmission, and I was just wondering if anyone can tell me why exactly that is the case? And how is that different than manually shifting a tiptronic or any of those "sport shift" transmissions which is basically simply an auto transmission that allows you to manually shift?

 

Tiptronic or sportshift cars are designed differently. I believe that if we manually shift our cars, it would damage it for sure. I think it's going to mess up the gearings. I am not sure. Anyone knows for sure what we would mess up if we keep manually shifting our cars?

 

I don't think you can hurt it, IF you're not doing something else stoopid at the same time. For instance, under normal driving, letting the tranny shift itself should be no less wear and tear than if you do it. But, if you're shifting manually and over-rev or if you're on slick roads and start spinning the tires and shift with all that going on, chances are you're going to hurt something. Lastly, if you're shifting up and down like crazy there will be extra wear because the automatic is going to find it's optimum gear as fast as possible to maximize gas mileage; its whole purpose in life is to run you around in the highest gear possible so the engine revs as little as possible. Pretty much the opposite of what most of us want to do most of the time anyway...

It was in my Carolla. I just shifted it manually.
