4L60E pressure regulator boost valve?
General Motors 4L60E Preventive Maintenance Tip
The pressure regulator boost valve and it's sleeve should be replaced every 40,000 miles to avoid major damage that occurs when accumulated wear in the boost sleeve causes insufficient pressure to be made available in reverse. We are seeing too many major repairs of the 4L60E at around 50,000 plus miles being traced to this boost valve and sleeve. The valve and sleeve can be replaced easily during a routine service of the transmission at an additional cost of around $50.00. This should be considered a must do maintenance procedure on the 4L60E.
