ferb - Penn synch is modified to grab better, so it's not so good for clutch type lim slip or hypoid gears.
When a fluid is modified for lim slip or hypoid gears, it is slipperier, and the synchros take longer to cut through the oil and bite. You get gear clash, and can really heat up the synchros and 'burn' them.
