| − | + | Note: I'm a builder with 35 yrs experience and we have a full machine shop with bore gauges. We do not replace any bushings unless absolutely necessary in any transmission. All the aftermarket bushings I have ever used except ones that are designed to be machined after installation, ALWAYS result in GREATER clearance that the OEM bushing your replacing. If you shrink them in dry ice and tap them in you will have better results but they still maybe larger than OEM. The only bushing we change consistently is the front pump. We prefer to find another part with a good bushing. | |

A universal cam bearing tool can be used to replace many bushings in the various automatics. It will not do very small bushings. Pictured here driving the bushing out towards the front. | A universal cam bearing tool can be used to replace many bushings in the various automatics. It will not do very small bushings.
