4L80E Saves Worn Valve Bodies
Actuator Limit Valve Repair Kit
At 100,000 miles the ac tutor bore will be worn.
YOU can check it, but the best answer is just to FIX it.
Worn bore causes low pressure HOT. Clutch, band, and converter slippage, wrong
gear starts, mysterious burnup, and Codes 39, 85, and 68.
Boring guide and cutter make the FIX an easy 5 minute job. Special valve(s)
have 50% more linear support, and os ciliate 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.
