Product: 3/4 Throttle valve
Price: $34.95

When cruising in overdrive (4th), your transmission will downshift into 3rd gear if the throttle is more than half way depressed. With the 3/4 Throttle valve, your transmission will not downshift into 3rd gear until the throttle is at least 75% depressed. This allows for cruising at higher speeds in overdrive.
We make these valves inhouse on our CNC Lathe so you can expect quality!
