Just installed. Besides the kit, needed a valve body gasket and pan gasket.
So far so good, much better, improved shifts. 1st gear hold really works.
Have to drive some more today to get a feel for it. I'll post later a better evaluation.
Like the box says, "For Professional Use Only". Requires drilling a few holes.
