Put this in my Civic Type R FN2 Transmission , i did not know the condition of it as the prior owner had it replaced some years back so it was not original. 08 model so not 07 with the manufacturer synchro issue.Changed gearbox oil on car purchase as preventative maintenance however going from 2nd to 3rd still felt a little "notchy" , no slipping or grinding but just didn't feel smooth. spoke to a trusted mechanic and he advised that Synchro's should have already been replaced at the age of the car. As i could not afford a transmission pull-apart yet i opted to try this product.Since putting this in going from 1st-2nd-3rd , no joke , it is like slicing a knife through butter. i have a feeling my synchro's are worn but the buffer this creates between the parts is ...

Noted easier shifting in a gearbox that was not easy when cold. The friction-reducing additive is likely to improve efficiency. Trusted product from Nulon.

This product does what it claims. Excellent for hard shifting gearboxes. Will work in diffs too but unsure if compatible with high performance Dana diff in BA BF FG FGX.

Since i put G70 Nulon in my gearbox, gear changing has been much smoother, especially on colder mornings.I have had the same positive experience of other people using this product.
Its a must have for any car , truck or tractor, I am a retired farmer and have Used Nulon additives for many years. They just work great and prolong the life of engines diffs and gearboxes
Have used this product for years, always found an improvement.
2nd & 3rd got difficult to engage after the engine warmed up, I used to get it into 4th just to loosen it up and then quickly push into 3rd or 2nd. A mechanic told me it's common to replace gearboxes in my model, so I was preparing to fork out $1500 which I didn't have.I took a chance on this product, changed gearbox oil and applied the Nulon stuff... Straight away it was smooth and felt like new!Wished I did this with my previous Utes
This Smooth Shift Treatment really works! Gearbox smoother and quieter from first start. Buy it on special and you are a winner. Simply squeeze into box while adding full synthetic oil.
Treated the gearbox of my 1986 Toyota Celica with this recently. I had previously changed the manual transmission's oil and the changes improved but first to second shifts remained crunchy, especially when trying to shift quickly or accelerating hard (eg freeway on ramp).After running the new oil for a few hundred kilometres I added the Nulon G70 treatment and wow, what a difference! Almost immediately (within 20 kilometres) the gearshift was beautifully smooth, and first to second shifts were going in a million times quicker, smoother and easier than before. Not bad for a car with 530,000km!Highly recommended for troublesome manual transmissions.
use this in all my gearboxs and diffs doubles the life of a gearbox even towing and keeps the heat down
