Got the Acura in signature from my Father acouple weeks ago. He said that at 90,000 miles the local garage drained 3 quarts of Honda fluid & added 3 new quarts of Honda automatic tranny fluid. Then again at 100,000 miles he did the same regiment but they added a bottle of Lube Guard Red on top of the 3 new quarts of Honda automatic tranny fluid. Car shifts smooth at 112,000 miles. Is this transmission going to be ok with his regiment so far? Is Lube Guard Red a quality additive? Trying to learn on here.
