    At 100,000 miles, you can bet the actuator bore will be worn. Worn bores cause low pressure hot, clutch, band and converter slippage, wrong gear starts, mysterious burn up and codes 39, 85 and 68.

    Our boring guide and cutter makes this fix an easy 5 minute job. Special valves have 50% more linear support, and oscillate less than half as much as the original design. This virtually stops the wear and makes the valve body more durable than a new one.

    This kit includes all the tools, valves and springs you will need to repair the Actuator Feed Limit on General Motors vehicles equipped with 4L80E and 4L85E automatic transmissions. If you already have the reaming tool and guide, order TransGo part # 48-ACT-VL6.
