I can do everything you have listed and more (if needed) and I’m probably less than half the price of a tranny shop.
And for the obx, when I install those, I take them apart completely. Debur any rough edges, properly install the spring washers (usually wrong from the factory) and retorque and loctite the bolts holding the assembly together (which is also, usually not even close) But it seriously is a good unit as long as it gets the above tlc.
