The problem with Royal Purple gear lube is that it's too slippery for the synchros to work properly, that's your problem. I'd recommend Valvoline dino GL-5 gear oil (75w90) in the tranny. You can pick this up from most local auto parts stores. Synthetics seem to accelerate wear in DSMs and Subarus with brass synchros.
