8L45, 8L90 Converter Feed Limit Valve Vacuum Test Tool

The GM 8L45 and 8L90 converter feed limit valve has an inboard valve spool fed by a hole through the valve into a blind port in the casting. This design makes vacuum testing the inboard spool and casting by traditional methods impossible.

The Sonnax converter feed limit valve vacuum test tool 154740-TL22 enables quick and easy vacuum testing of the inboard testing location. This tool can also be used to test the outboard location. If excessive wear is found, repair by installing Sonnax drop-in converter feed limit valve kit 154740-19K or reaming the bore and installing oversized converter feed limit valve kit 154740-22K.
