I've been using Motul Gear 300 GL-5 in the transmission and diff for over 100,000 miles (changed regularly) and never had an issue with it. If I ever had a problem with shifting, it was because the throw out bearing burning itself up, or the transmission mount having too much flex and lash when shifting (fixed with whiteline part).

Its your throw out bearing. At your mileage its very common for the factory throw out bearing to go out, cause crunching shifts. Get the new revised throw out bearing and your shifts will be crisp again.
