Not really sure if this helped or not. I can say this, I used to get a little whine in second. I changed the gearbox oil and added this, no more whine and I am convinced gear changes are smoother, how much of that is down to the oil or this product I do not know. It most certainly hasn’t done any harm if that helps?

C,est marche Biden Merci beaucoup, it works very well, the delivery takes a long time, so order in plenty of time say 15 days before you need it.

Works as intended. I only used one tube (well almost one but we will get to that) when for my gearbox size I should have used two, and the gearshifts are a little bit smoother and the box seems to grind less. 350z boxes are notorious for syncho wear and chunky clunky gearshifting issues from 1st to 2nd gear which is why I bought it. I would recommend it. Watch out if you try to squeeze the last bit out the bottle the applicator tube can pop off the bottle, and I managed to spill quite a bit this way. Just don't be as aggressive and you'll be fine
