Thanks for the feedback, no sealant it is then.

I’ve read all the threads and discussions about changing versus not changing the fluid. Since my transmission has under 20k on it since remanufacture I think it’s a probably good habit to get in to. It’s being asked to handle roughly 40 fl lbs more torque from the 4.6 than the 4.4, so fresh fluid often might prolong it’s life.
