I have a Jercio DR-4 in my road race car. I'm aware the drag box is made using a different gear hardening process and is not best suited to road racing. However I've road raced the car for years with Redline shockproof lightweight in trans without a problem until now. Several gears failed in the trans so I sent it to be repaired.
I was advised by the builder to use Mobil 1 or Royal Purple and stop using Redline shookproof because it is detremental to the gear material which I will do, but would like any other perspectives on the advice.
Thanks in advance for your thoughts and time.
