Why are my 6L80, 6L90 converters not working?
Our theory as to why 6L80, 6L90 converters fail like they do is related to the shape and thickness of the JMBX piston. The thought is that the “bowl” shape of the TMBX is better suited towards a more even apply, and because it’s thinner, the TMBX piston has the ability to flex and better conform to the front cover.
What kind of clutch converter does a 6L80 use?
Most full-size trucks and SUVs with a 6L80, 6L90 use a JMBX full-size (300mm) style converter. It’s a single-disc, non-captive clutch unit that is somewhat similar to late 300mm 4L60-E converters.
