Correction:

The Sonnax accumulator piston incorporates an O-ring for positive sealing and annular grooves for better centering and wear prevention.

Wear at the multiple accumulator bores on TF-80/81SC, TF-60SNand TR-60SN units is very common. At the clutch and band locations, wear allows component apply oil to exhaust, resulting in delayed engagements, slipping shifts, and burnt clutches and bands. Wear at the line pressure accumulator allows throttle signal oil leakage, which can result in reduced line pressure. The Sonnax accumulator piston kit 15741-14K incorporates an O-ring for positive sealing and annular grooves for better centering and wear prevention.This kit fits in several locations throughout the valve bodies as shown.

You need this if...

Visual inspection ofthe bore often shows shiny patches of wear. If wear is visible, perform a wet air or vacuum test in the necessary locations as shown. Vacuum test must hold a minimum of 18".
