Moving past the premise that my 4L60E transmission is currently in the repair shop due to a worn out 3/4th clutch. In order to slightly 'beef up' my tranny rebuild for weekend trailering a 2000lb boat in moderate terrain, what specific parts might I ask to be installed (vs factory OEM)? ie: 4 vs 5(? or more?)3/4th gear clutch pack assembly, corvette servo?, beefier sun shell, 5 pinion planetary?, bigger boost valve, single vs dbl gauge sprag, 7 vs 10 pump rotor vein, and I have read several forums talking about having the valve body drilled out in a certain passage? These are the possible upgrades I was hoping to get expert advice on. I would appreciate any suggestions that would help me decide during my rebuild process. Thanks! Tom

Any chance you'd care to elaborate on what you mean by that reply?
