automatic overdrive

[t-topV6]

ok, i have never seen an automatic overdrive (like on my car). but, i did some searching and found most people like it better for racing and it gets better MPG. so why is there even a drive? if its slower and less efficient... oh and i also found a thread where most people seemed to think it was ok to shift from D to neutral and back, on the highway to rev it... ive always been told not to shift from neutral or park when reving as it may damage the tranny...

Re: automatic overdrive

as long as u match the rpms to what you shifted at the Trq Cnvtrt takes care of the rest and is isnt harmful

Re: automatic overdrive

what about the drive question?

Re: automatic overdrive

drive is better for racing because it doesnt allow your car to shift into that "5th gear"

Re: automatic overdrive

Drive is just 3rd gear in an automatic. It's a 1:1 ratio gear in our car. As far as racing is concerned it makes no difference in my car. The car will hold whatever gear it needs as long as it can. Mine shifts into 3rd (or Drive ["D"]) at abour 74-75. I don't know how far Drive will pull before it shifts into overdrive, something like a 0.76:1 ratio. I do know that my the torque convertor never locks in under WOT though.

Re: automatic overdrive

seems to me 3rd gear end at about 114 with my 3.42s.

With a very conservative trip from 0 - 45 I would swear my car shifts 4 times. That would be a 5th gear, but i'm A4. Anyone else notice this?

Lol, didn't we just have this discussion a couple days ago?

Yeah, we did: http://forum.camarov6.com/showthread.php?t=82438

Car goes from 1st-2nd, 2nd-3rd(Drive), 3rd(Drive)-4th(Overdrive), 4th with TC lockup. Four "shifts".

Re: automatic overdrive

I figured it had to do with the torque converter. I missed that thread though. Thx for the link!

Re: automatic overdrive

So why are people talking about a 5th gear? isnt Overdrive the 4th and final gear? I'm a little confused now.

Did you miss this post? The 4L60E has 4 gears. Some people feel the torque convertor lockup. This is the extra "shift" they feel. It's not a shift at all, but the RPMs do drop about 200 or so. Check out that link if you wanna know more.

Re: automatic overdrive

I had been watching this happen on my auto for 10 months now going up a 5% grade To work everyday as i roll up to roughly 40-45 feathering the gas pedal an i go from 1800 RPMs to 1600 RPMs without feeling an actual shift. I thought it was just the computer doing some gas saving technique. I'm a fricking moron. Least now i know.

Re: automatic overdrive

i need a video camera bcuz when mine shifts 4 times the rpms drop at LEAST 600 rpms each time...
