hell my chevy truck will hit od at about 35 if your easy on the pedal.....

but of course!

heck, in the right car, you expect to feel the shifts.. but I guess that'd seem a bit crude in say, a Benz.

Main thing that brought up that comment was that I got used to going through towns with traffic and a speed limit around 45, and shifting in and out of OD. I used to drive through that a lot when I was commuting to school, second I'd get going and shift into OD a light would turn red or a truck would slow down and I'd keep going back and forth, aggravated me I guess.

"a shift kit can fix that though. you feel it in my car every time it shifts, which can be harsh if you change speed a lot and have to shift (manually) often."

But that all important tire chirp is worth it :)

below 45MPH I don't see OD kicking on anyway.. you'd be in third or lower gaer at those speeds anyway, so really OD is only an issue for highway driving, and unless you're unable to keep a fairly constant speed, it shouldn't shift much at all.
the overlap in shifting is there to make the shift softer so it's not as harsh to people who don't like the feel of a boot in their ass every time the auto trans shifts.. heh

Only time I don't use OD is when I know that the car would be constantly changing back and forth from Drive to overdrive, or OD would be at so low of an RPM that it would be stressing the transmission due to torque converter stall and heat buildup (assuming the converter doesn't lock until a certain speed). In town, putting it in drive will save gas due to fewer shifts and also help the transmission last longer since the tranny isn't constantly shifting back and forth, which heats up the transmission since the gears are constantly changing, and in many cases, the torque converter stalling since the RPM is so low. New cars are designed to have a mushy shift because people percieve that a soft shift is easier on a transmission, but really the reverse is true. Everytime a transmission shifts, there is an overlap period in the shifts that forces the transmission to slip in between gears, which gives a softer, smoother shift, similar to if you rode a clutch really bad in a manual tranny. All the power in between the shifts transfer to the clutches and bands in the form of heat, causing them to weaken over time. It's also wasted power since you're burning gas during that slippage and not getting a lot out of it. That's the premise behind shift kits, they can improve the life of friction materials in a transmission by over double. That's why I try to keep a tranny shifting as little as possible. Of course, I started driving in the early 80s and during the 80s tHe first OD automatics had somewhat weak OD bands when they started, they've gotten much better over time. If I know I'm going to drive 45+ and will be on a steady cruise, I use OD as my normal gear, if I'm in town and the car would be shifting constantly, I just leave it in drive until I hit the highway then put it into OD.

Manuels don't do shizzle but tell you where your defrost is. LOL.

Turn the car on, release E brake, put in drive and go. Only an idiot would not take his car to get a routine oil change, brakes, etc.. You don't need the manuel to tell you why your brakes aren't as effective and are squeaking like nails on a chalkboard.

lol, i wont be able to tell, im not the only one who drives the car. Id drive a standard, the clutch just seems like a pain in the ass too me

you know I live to tease you!

no I was serious about if you could drive a stick. hey goole for "why double clutch" and you can learn to drive a stick without using the clutch at all :) very handy if yours goes out on a long trip.

try leaving the car in "OD" and see if your gas milage and drivability improves. Let me know if you see any difference after a week or so.

so im stupid because I didnt know that was automatic overdrive? My manual is falling apart and they didnt teach us crap in drivers ed. next time i wont ask lol

people who want to know what the hell tehy're doing behind the wheel of a car.

people who don't take the time to elarn their car are the ones who cause a lot of accidents and have no idea why the wreck their cars, or why their cars break down for "no apparent reason!"
The reason is you're a moron and didn't bother to do routine maintenance, or learn what the car requires, and how to take care of it. Just like anything else, cars last about as well as their owners take care of them.

and yes I realize your statement was meant in jest.
