6R60, 6R75, 6R80

Symptoms:

• Excess wear of center support & case lugs at contact points
• Excess total transmission endplay
• Difficulty setting endplay

Cause:
The center support frets and wears where it contacts the case lugs, resulting in excess endplay.

Correction:
Restore proper endplay, save the center support and prevent future wear by machining the center support and installing Sonnax center support snap ring.

In Ford 6R60, 6R75, 6R80 transmissions, movement between the center support and case lugs causes fretting wear on the face of the center support, resulting in endplay exceeding specification. Machining the center support contact face and installing this Sonnax center support snap ring between the case lugs and center support restores endplay to proper levels, allowing the support to be reused.

• Increased contact area between center support and case lugs combats future wear
• Salvages worn center support
• Preserves OE endplay tolerance
