gear changes have improved
I changed the oil on my Honda Jazz and added Wynnes transmission treatment. Previously I had just changed the gearbox oil. With Wynnes the gear change is definitely smoother and less chunky when driving from cold. I would recommend this product.

I have a Triumph TR6pi a well known model for engine and gearbox leaks. I used this in my gearbox which is fitted with an overdrive, I was very disappointed as it did not live up to expectations the gearbox still leaks oil even after 2,000 kilometres.

I wouldn't waste your money
This product never worked for me. It wouldn't even seal a very slightly weeping rear diff seal.

Effective on all manual gearboxes.
I have used versions of this product since the 1980s and have always found it improves smooth gear changing and reduces transmission noise.
