Check converters before they’re installed in the transmission or vehicle. Even if you purchase converters from a distributor, the end play gauge confirms their rebuild prior to putting it in your transmission. Prevent your reputation from hanging on the reputation of your converter rebuilder. The End Play Gauge is affordable; it pays for itself by preventing one comeback. Check internal clearances of most torque converters, foreign and domestic, from the VW to the E40D to the V10 dodge. Designed for ease of use, the end play gauge simply requires you set the converter on the fixture, zero the dial indicator and press the handle to read the clearance.
