Ok. I know people (with more transmission knowledge then I) have talked
about the difference between GL4 and GL5. People have also talked about
Redline and Mobil which I have not used. I have been using the Motul Gear
300 after reading Mike Kojima discuss it in the SCC issue or maybe one of
his other writings. I also checked the info on the bottle and it is listed
for both GL4 and GL5. In the past I was told that if it is rated for GL4
and GL5 then it is OK and not a problem in GL4 only transmission. To be
sure I e-mailed Motul to confirm and they replied with this
" GL5 is an improvement to GL4, so NO, the corrosive problem is not a major
concern. As development goes on we find better products that are less
hazardous and more efficient. Gear 300 is fine for a GL4 app.GL5 is an

Now I know they make the stuff and are biased but tend to think this makes
sense to some degree. Is it not logical that a GL4 and GL5 rated product
would be OK and a GL5 only rated product would not. BTW the Motul solved my
shifting problems and seems to be doing a good job. If this is a poor
product for my application then I will switch but I don't want to go back to
dino oil for shifting purposes. Any recomendations.

Couldn't tell from the picture what I was supposed to see. Did the person
use GL-5 fluid which is corrosive to >synchros?
