1981-90 GM 2004R Constant Pressure Valve Body™
Innovative TCI® Constant Pressure Valve Body™ avoids incorrect TV cable installation – the most common cause of 1981-90 GM 2004R transmission failure
It is clearly the most confusing and overlooked step involving proper installation of your automatic transmission – TV cable adjustment. In most cases, amateur (and many pro) installers simply leave this critical cable either disconnected or improperly adjusted. The result: clutch damage and ultimately total transmission destruction. The TCI® 2004R Constant Pressure Valve Body™ avoids all of those problems by ensuring proper line pressure, regardless of TV cable positioning.
In the past, the TV cable adjustment on 1981-90 GM 2004R transmissions required significant mechanical ability. Installation of the new revolutionary-design TCI® 2004R Constant Pressure Valve Body™ helps avoid transmission destruction in both stock and aftermarket units, by ensuring that clutches and bands are applied firmly to eliminate slippage. While the TV cable still needs connection for proper part-throttle transmission shift operation, the TCI® 2004R Constant Pressure Valve Body™ provides more freedom as line pressure is fixed with no chance of encountering a low line pressure condition.
