I don't know of any "Mechanic-in-a-Jar" that will remove contaminates from your transmission. There are a few that will turn it into junk though. First, do as Jay, from Broader Performance, said and check the fit of the governor body to the output shaft. If it is loose then take the ball out of the output shaft and place a small piece of rubber under it and re-install the governor. Then remove the governor valve section, clean it with brake parts cleaner and remove and polish the valves with 600 grit emery paper and a drill. Use a little kerosine to help keep the paper clean as you polish. Clean again with brake parts cleaner (valves and body). Assemble the valves back into the valve section of the governor with a thin (THIN) coat of Vaseline on the valves. Put the extension housing back on and check the operation.
Change the oil and filter to clean the debris out of it and refill to the proper level.
(Jay, from Broader Performance, is the best transmission man That I have known. I run with some of the best but when Ray talks I listen.)
