JoeG is right. . I had tried quite a many times to find the adjusting button, today I took the cable out of the steel plate and looked at it. The actuating button is on the wheel side not the engine side. It is flat with the housing of the cable, its about . 75"x. 5". Push it in and the jacket of the cable slides in and out. Pull out towards the rear of the rear of the truck, it makes the shifts later and firmer. Push in towards the front and it makes the shifts smoother and earlier. I measured the slack distance of the blue plastic hook that connects to the throttle linkage, and adjusted my cable back about a 1/4 to 3/8". I ended up with 3/16" rearward from the throttle connection. Made the shifts much later, the firmness didnt change cus I have a rebuild. I`ve been trying to make that TV button work, and I FINALLY got it! wooooohooo
