87 bird throttle valve adjustment??

Even once you have everything set up properly, you may find that you still have to let off the gas to go into OD. This is *basically* designed into the valvebody.
Regardless, though, you really should keep your foot in it until you reach the speed you want, and then let off so it "clunk"s into OD without a load on it. The OD bands and force from the servo are notoriously weak in these trannies, so you'll make it last a lot longer this way, especially if you use OD a lot. If you can, avoid using OD unless you'll be driving above 45 mph for at least half a mile.
