Hey all I'll be home soon so my christmas present to myself is the switch to Royal Purple oil tranny and gear lube. Where is the best place to purchase it all or should I go right to RP to order and buy it??

I have found it on EBay before, 5 gallons, about $130 shipped.

i have the auto tranny and the chrysler 9 rearend in my 05 just wanderin if uguys would also know how much royal purple tranny fluid and gear oil it takes to do a service on these and also what about tranny and rearend gaskets
