Question 1

I have some trouble with my 5th and reverse gear it takes the couple of tries to get there will this help ?

Accepted Answer

It all depends on what the trouble is with your 5th gear we had a whine noise and it always helps with a smoother gear change. It should improve after 100 miles
Try gear box oil first that might cure your problem

Question 2

Is this suitable for a manual gearbox that uses ATF oil.

Accepted Answer

I don’t know what ATF oil is. If it is Automatic Transmission Oil, I would think the answer for Torque Converter transmissions is NO. It is great for stopping the ‘crunchiness’ u sometimes get in Manual transmissions. Iv used it in 3 ‘manual’ transmissions..all Honda, & it has helped to ‘smooth out’ the ‘crunchiness if u change too quickly’. Torque Converter automatic transmissions require the gearbox oil to be a certain ‘density/thickness/viscosity’ for the gearbox ‘engagement & ‘disengagement process to work properly.

Question 3

Have a Peugeot 108 on a 15 plate with suspected noisy diff bearing. Would this be suitable to quieten it down a bit?

Accepted Answer

I’m not sure whether gearbox oil gets into the diff. In my own experience, where the gearbox has been a bit notchy & crunchy (usually 1st to 2nd, Slick 50 has enabled gear changes to be much more fluid (forgive the pun) and silent. I have now used it in 4 gearboxes (in 4 different cars, I might add) & I have noticed immediate improvement, and improvement over a sustained period. In my opinion, it is a very good product.
