Landcruiser 200 Series
What are the benefits of the Landcruiser 200 Series Valve Body Upgrade?
There are so many but firstly, it’s to give your transmission a longer life and prevention of failure. The additional pressure placed on your transmission when towing a caravan / heavy loads and hard beach driving puts a tremendous amount of excessive heat on the automatic transmission.
The 200 Series Valve Body Upgrade is the perfect accessory to provide quick, clean shifts with firmer convertor clutch operation that reduces flaring and gear hunting in your transmission. You will see a reduction in heat, fuel consumption and enjoy a better driving experience. The upgrade is a must to give you extra confidence when experiencing heavy duty off-roading / TOWING by improving the shifts and reducing slipping in your transmission.
Have you upgraded your engines performance?
Then we highly recommend this upgrade be carried out in conjunction with any engine performance improvements. As engine tunes alter the torque curve, they often adversely affect transmission behaviour and shift quality. The upgrade gives you the confidence that your automatic transmission does not become the weakest link.
The valve body is the brain of the automatic transmission and the control centre of the automatic transmission. It is a maze of channels with valves and springs. The valves are controlled via hydraulics that direct hydraulic fluid to the numerous valves and springs which then activate the appropriate clutch pack or band servo to smoothly shift to the gear for each driving situation.
Enjoy your driving experience after the valve body upgrade!
When a valve body is opened the oil can applies pressure to a clutch or directs the oil to another valve. By combining a series of valve open / closes, the transmission can engage or disengage certain clutches which in turn will shift gears, engage the torque convertor lockup or neutralise. This means that one set of valves on the valve body select first gear, while another set of valves might engage reverse.
By re-calibrating the oil flow using modified valves, separating plates and springs, we can affect how clutches apply. This provides better lubrication, increases longevity and better cooler flow.
THE ADVANTAGES OF THE UPGRADE …
- • Providing quick, clean shifts with firmer convertor clutch operation
• Compliments any engine upgrades due to higher clamping forces
• Produces better cooler flow
• Extends the life of your transmission, especially if you are towing
• Reduces transmission fluid temperature
• Increases power efficiency • Reduces flaring between gears
• Improves fuel economy • Reduces maintenance costs
