O/D On or Off?

[TruthWalleyes]

Great topic.

I've got a 98 Olds Bravada. OD or 3rd gear. I pull in 3rd gear under 60mph and pop it into OD when going faster. When in OD i never set the cruise and i allow the vehicle to lose speed when going up hill rather than allowing the sudden shift into a lower gear.

If i don't switch out of 3rd when going faster than 60 my RPM's go through the roof, and the bottom of the gas tank seems to fall off.

Am I doing this wrong?

I think the key with the gauges is they are electric and tend to not be accurate

That's a 4.3 in the bravado right? Depending on the size of the boat you could be okay in od at lower speeds. I have a 4.2 in my trailblazer and cannot pull my boat in od at all but its got a 3.42 rear end. Basically I cannot get out of its own way at all gutless. But if u have a 3.73 rear end it should tow much better and ur right u might as well have a 6.0 liter for mileage when towing out of od in any vehicle mileage is awful.

You say the pressure gauge doesn't show pressure but is either off (showing no pressure) or on (showing normal pressure)? What good is that?

They're dummy lights masquerading as gauges.

It.s a 4.3L and i have no clue as to what the rear end gear ratio is.

I'm in process of figuring out how to get a different truck just to pull my boat that gets decent gas milage and is reliable without spending too much money.
