Default Drive Or Overdrive

Ok I know I'am going to be labeled a Dummy , But here it is. While in town should I be driving in drive or is it ok to just leave it in OD. 1992 Automatic.

The jury is out on this one. Some say drive in town and only OD on highway and others say OD all the time. Personally I drive in OD all the time in both my cars. I have a Volvo T5R with 213k miles and never rebuilt and my vette has 150k miles and just rebuilt. Pump gave out on the vette, nothing caused by what gear I was in. So do what you want, just remember your tranny is pretty good about being in the right gear, you only hurt it if you drive at low RPM's and that is not much.

Personally I drive in OD all the time in both my car and my Dodge Dakota Quad Cab. 60k on the Vette and 65k on the Dodge, neither with any problems.

Sometimes, when I want to, I will switch them both down to Drive, but only when I feel there is a need for instant punch.

I only put or leave my tranny in OD if I can sustain 39 plus MPH, in town where most of our speed limits are 35 MPH, of course I exceed it by 5 MPH, but I was told by a tranny guy it was harder on it to have it constantly going back and forth.Works for me

It is fine to leave it in OD. It will shift as programed. For snappier performance, many people run them in D. No harm done either way.

As long as speed as less than about 40 mph, I stay in 3rd.

If speed limit goes above that, I kick it into overdrive.

A guy I work with mentioned this to me as well and I asked a reputable tranny shop owner and he said as others have said......it's fine either way.

You know, of all the vehicles i've driven, i've never noticed a difference between driving in either one. No performance or gas mileage difference either. Although i'm sure it'd make a difference on the highway.

What rear end ratio do you have? if its a 2.59:1 id stay in D til about 40mph, if its a 3.07:1 id just leave it in OD unless you want to hold 3rd longer. Also depends what speeds the TCC locks on a 92 around town(id imagine this would also depend on rear end ratio), and wheather you would rather be in 3rd with it locked or OD without it locked. Its really all up to how you want to drive the car!!

I have 307s in my 87, and I do notice a big difference in instant average (miles per gallon) when I'm in OD, much better, but I won't bog my engine for anything.

I Live In Australia.

I Got mine imported and when i bought it I got told several rules.

You know... Just like in gremlins.

RULE 1 - Don't EVER Drive around on reserve fuel... It will make the car surge.

RULE 2 - Dont ever Stick normal unleaded (92 Octane here) in the car or it will Ping, Knock or whatever you wanna call it. (but at work I used to get 38L a week for free of 92 octane - But the car pinged badly under normal acceleration and performed like crap - 98 Octane is all I use now and not a single knock).

RULE 3 - Don't drive in OD unless you are on an open road above 40Mph sustained, or You'll damage the tranny from all the start stop driving and tranny shifts.

I go through a bit of fuel and today, after reading this thread I started driving in OD and my average fuel is considerably less.

But at the end of the day I dont like driving around and my poor 350 V8 is only doing 900RPm at the speed limit in our urban areas. So i reckon im gonna go D over OD until im over 40mph sustained.

Now I just wanna cut off my mufflers and weld straight pipe from the cat back (After reading another thread)

Is this a good Idea or should i go with a cat back exhaust...

At the end of the day - I LOVE my vette the way it is.

Thankyou Corvette Forum - VETtES for LIFE

That is something I did not know. What damage occurs?
