68RFE Low Reverse Sprag Update

Product Description

TCS low/reverse sprag update for the 68RFE. It replaces the failure-prone OEM low/reverse sprag with a stronger, more durable roller clutch design, made for high-performance and towing applications.

Why it fails

The low/reverse clutch is on only while the output shaft turns below 150 rpm. During hard acceleration or burnouts, once driveshaft speed reaches 150 rpm, the clutch releases back onto the low/reverse sprag. The OEM sprag does not stand up to that stress for long, and failure results in the loss of 1st and 2nd gear starts.
