• Bang shifts
• Bind-ups
• Excess Reverse pressure & distorted housings
• Flared upshifts
• Harsh upshifts
• Low cooler flow
• Overheating
• TCC cycling
• TCC slip

Excessive solenoid pressure is caused by line pressure side-loading the steel solenoid modulator valve and the continuous oscillation of the valve, which wears the cast aluminum bore.

The modified valve and high-grade aluminum sleeve allows the bore to be refurbished, and prevents side-loading of the valve and future wear.
