·Having replaced the gearbox/di
Having replaced the gearbox/differential fluid on an '84 308 QV with Royal Purple maxgear 75-90 LS, and been amazed with the results, I am now contemplating the same for my '72 365 GTC4.
Understanding that seal technology in 1972 probably wasn't what it was in 1984, and the fact that I have NO LEAKS at this time in the box or rear, is this a good thing to do? 2nd gear's a little slow, as is 3rd, which I've heard is common in this 'box.
