Salvaging Late-Model 4L80-E Stators
As if having another wave of cracking pistons was not bad enough, the problems with the second-generation stators were even worse. The first issue rebuilders noticed was excessive wear in the stator housing where the roller-clutch inner race contacts the housing. On some converters, the inner race would wear its way out through the stator housing and into the impeller hub. This was especially problematic because – unlike in the first generation – the impeller side of the stator was not a removable stator cap.
