I would just leave it in overdrive.

Theres no reason to not just leave it in overdrive. Let the PCM do its job. Thats the way GM intended it to be drivin.

I dont disagree... exactly, but i drove my lt1 powered caprice in d on short drives under 45 mph, yes it was a police car and yes if anyones familiar with em theres a sticker in most of them that says shift into overdrive during highway or highspeed pursuit. I do like that a trans shop chimed in, as i respect and value the opinion of the professionals.

if you have a high stall (over 3200), keep it in D until around 60mph. if you keep it in OD for speeds under 40, the comp/tranny will search for gears. at least in my case it's how it is, i have a vig3600. but if you have a stock stall then i don't see why OD is a bad choice.

If yours is searching for gears and constantly shifting then you have a tuning issue. Even with a higher stall converter if you have the shift points setup right it should not do that. I have always just driven around in OD. No reason to use D only.

It doesn't do it much, but I can tell a difference in OD. The rpm's seem off, so I just leave it in D when under 50mph.

If it ever hunts for a gear, you have a problem. It is most likely the tune, but it could be something else too.

you guy right, I keep it in D and around 45mph, I can feel my car searching for gear, I shift it to OD and RPM drop and run smooth. Imma keep it in OD , the last owner keep in OD for the last 12 years lol.

This is interesting, I had my car tuned by LG back in '04 and it always seemed to me that my car hasn't ever been to it's potential. The guy didn't really take a good amount of time tweaking my tune. Maybe I should get it done again. He had told me to leave it in D until 60-65. Guess that was false advice!

It depends a lot on the car, if it has a stock TC the leave it in OD.

I have a 3600 converter and it doesn't like to lock up under 48 mph, and running around the city unlocked will heat the trans up. I made a custom tune for this, I set the 3rd gear TCC apply to a low mph, a few mph higher than the 4th gear shift point so it won't lock the TCC during normal driving in OD. But if I'm stuck at say 35-40 mph I can pull it down to D and the TCC will lock up, it'll run at the same rpm (+/- 200) but this prevents the trans from running hotter than needed.

it's not good, gotta be around 12 or so.




my stall locks up @ around 40 give or take depending on how i apply the gas. i'll try keeping it in OD and see if it makes a difference.
