    i would assume that you are putting it in D and still feeling a fourth shift? if so its not over drive its T/C lockup. its perfectly normal, just annoying some times. you can get a kit from summit or jegs to turn it off or back to the normal way

    Actually, if you have a lockup converter you have 5 speeds /forums/images/graemlins/thumb.gif Shifting into OD and lockup is normal operation. If you have big, oversized tires that bogs the vehicle down or climbing a long grade or are towing a heavy load and it keeps consistantly shifting in-n-out of overdrive, you can pull the shift lever down to "3" and it wont shift into OD or lockup. If just normal driving, let it go.

    any truck with a 700 R4 in it from 1986 is not going to have this pattern P R N (D) D 3 2 1, its going to have one like this P R N (D) D 2 1. if you have bigger than stock tires, or low numericaly(high physicaly) gears like 2.73, or 3.08's you should run in D most of the time any way. when you run a 700R4 at low speeds in OD then it isnt moving fast enough to move the fluid to cool it off.
