tcs sell a harden pump gear if you want to swap them out...I would get a reinforced band strut also..

check to what the kickdown lever ratio is ....should be at least 4.2...I use 5.0 in my race trans...

only other thing would be a 24 spring kit for the front drum from tcs,,,if you are spinning it upwards of 6000 rpm...

just make check all your clearances are correct....special tools...need to compress front clutch pac somehow to remove and replace lip seals..plus need to remove and replace pump bushing...front drum bushing and tail shaft bushing....probably take all three items and bushing to locate trans shop and they should be able to do that in a couple of minutes...you need to disassemble the pump to get to the bushing
