Th400 case repair kit. Condition is New. This kit is for worn out center support case lugs, brings them back to factory spec's , when the center support bolt is broken or loose its most of the time because of worn out lugs in the case , this is the fluid apply passage to 2and 3rd gear clutch pac's. Almost every TH400 case is wornout at in this area , I ve used well over 50 of these kits and they work great!! Years ago we would junk the case and replace it, Now th400 cases are getting harder to find.
