There are at least 3 different ways it can connect to the throttle body/carb, and in any case misadjustment can kill the transmission very quickly. It's not like a traditional "kickdown" cable/rod where you can drive the vehicle without it and it'll only 'kinda shift funky.'
Its a factory installed AOD. Shifts into overdrive about 40mph at zero throttle based on what the speedometer says. The tires are not stock size so the actual speed is unknown.

I may need to adjust the TV cable I don't know. I'll probably have the transmission shop do that so I know its right....

JeffB There is an AOD site with a lot of info you might want to check out: www.clickclickracing.com

AOD shifts hard into OD

I just bought this truck so I have no history of it.

The transmission i'm sure is an AOD. It shifts pretty hard into overdrive and at lower speeds (in the OD range tho) it wont shift into OD until i let up on the throttle, even if I am only lightly on the pedal. This is costing me gas mileage, although it might be normal IDK.

I know the hard shifting is not normal tho. All other shifts and functions are fine.

Any idea what I need to do? Could it be that the rear tires are not stock sized?
