before changing my gearbox oil I asked Redline for advise on what product to use.
Originally I was looking to use their Shockproof gear oil, the following is pasted from their email reply:
<strong>The ShockProof gear oils are very unique and generally recommended and better suited for race/speciality use, they can be too slippery for some synchro designs and low temperature characteristics are better with some of our other lubes.
I would expect that this transmission uses synchros and I would recommend the Red Line 75W90NS for good shiftability and all around operation.

Note the "too slippery for some synchro designs".
