Hope this isn't a dupe ... paged through all the threads and didn't see one so here goes.
When I got my '08 Bullitt, I thought the (vaunted Tremec) gearbox was a little 'notchy.' Posted on a forum--maybe this one, but maybe not--and was advised to try Royal Purple Synchromax. Installed it, and after a while it felt like the gearbox was a little smoother; yeah, confirmation bias and all that but, apparently, the fluid somehow 'conditions' the gears and synchros. Flushed and refilled and the gearbox was going strong--on original clutch and brakes--at 135K miles, so maybe there was something to it (flushed and refilled again at about 100K). Note my other two fun cars are old British iron, so I've gotten pretty good at persuading the lever into gears (I've seen the wear on brass shift forks). The Getrag feels OK to me so far, but I'm wondering if anybody has tried a different fluid--Synchromax or other--and what the results are?
Great forum, BTW. Some real car lovers here.
