For those that understand how the AT transmission works on this platform...Is it ok to let off the gas in between up shifts? I like to simulate driving stick when in manual mode. It could be a habit from driving stick before. (say im in 1st gear 60% throttle, let off gas, shift into 2nd, add gas again).

Sometimes I notice that the car hesitates to find the right RPM it should sit at when changing to the next gear when I do this.

So I went ahead and experimented with how the car likes to react. When driving regularly 40/50% or so throttle (2.5-4.5k RPMs), it doesn't affect it a whole lot. Letting off the gas, shifts the car slower I've noticed, but it sounds better in my opinion than a fast automatic shift. (Yea, i know its still an auto, it just sounds more pleasing to more my ears)

However, when in the higher RPMs and WOT, I've noticed that the car doesn't like it because the RPMs have to drop dramatically in order to sit at the correct RPM in the next gear (its more obvious in 1st, 2nd, 3rd and sometimes 4th gear. Gears 5th and 6th don't really make a difference since they're highway speeds.) Im guessing this has to do with the gas cutting off when depressing the gas pedal before shifting into the next gear.

Anyways, does anyone else do this? Try it for yourself if you own an auto, and let me know how your car reacts or if you understand what im trying to say.

Bottom line is, Is it ok for my engine and transmission? I don't to be hurting my car not knowing so.

Thanks

There's no point in "letting off the gas" in between shifts on our autos, it's not a sequential dog box or anything like that it's a torque converter automatic that shifts quick on the downshifts. You're actually causing the TCM to slow your gear changes and heavily confusing the TCM logic when you do that.

I've only letting off the gas when hitting the paddle in odd circumstances, but never intentionally, and there is a noticeable delay. Also I let my friend drive my car and the car would jerk around alot with the latest TCM update and I realized he was being odd and letting off the gas between shifts.


If you want to pretend you have a manual, buy the manual
