The best way to adjust the TV cable is to install a pressure gauge at the transmissions pressure port and adjust the cable until the gauge reads 35 psi at idle in Neutral or Park. This adjustment is critical, because if you incorrectly adjust it, you risk transmission failure. See a trusted transmission shop if youre in doubt. The rule of thumb here is shift quality. If the transmission shifts too soon, you dont have enough cable tension. If it shifts too late, or not at all, you have too much tension. Attaching the TV cable to the carburetor is simple. Always remember that the throttle should pull the cable.
