Heavy Duty Full Manual Valve Body
Taking the Extreme to the Extreme!
Of course, if the Nomad Heavy Duty Valve Body or the Extreme Heavy Duty Valve Body are still not enough for you, then let me introduce you to the Full Manual Heavy Duty Valve Body. This upgrade is designed only for comp trucks.
The Full Manual Heavy Duty Valve Body removes all ECU interfaces from the transmission so that you have full control over the shifting of the transmission.
There is no pressure control as pressure is set to full power of the pump at all times.
There is no automatic shifting – you move the T-Bar to change gears
There is no automatic torque converter lockup – you need to switch it manually if you want it
There is no ECU to protect from water ingress
For transmissions with an electronic overdrive, it becomes a little more complex as you will have to switch the overdrive gear on and off manually. If you leave the overdrive switch off, as you move the T-Bar the transmission will shift 1-2-3. Activate the switch to acheive 4th. If you leave the overdrive switch on, as you move the T-Bar the transmission will shift 1-2-4. Deactivate the switch to acheive 3rd.
