F430 actuator leak

I would like to thank all of you that have provided input regarding my F1 shifting issue. I removed the actuator and tighten the three bleed screws. One was a 1/16th loose, 2 was a 1/8th loose, and 3 was a 1/16th loose. I cleaned the actuator cover and used Loctite product.#515 and reinstalled. I flushed the system and refilled it with the Parkello product, It absolutely corrected the shift problem, infact it has never has shifted better. Unfortunately, I have a slight diff fluid leak from the actuator cover. I plan to remove and replace nuts and washers and reseal. What is the best sealant to use for this application and do you recommend twerking to 40-50 inch pounds? Special thanks to Flash 32 for his input on the flush procedure. Many Thanks to All.
Tom Ruland.

 

Removed actuator and tightened three screws and reinstalled with the correct sealant and then flushed the system and the problem was resolved.
