T90 Trans Oil
Hi Wayne & Rob.
Great post Wayne.....Rob sent me a similar explanation many months ago as I was looking for a suitable transmission/transfer case oil.
At the time I settled on Redline MT-90. It states that its....
•Safe for brass synchros, as it lacks the reactive sulfurs found in most GL-5 oils that cause damage
•Recommended for GL-1, GL-3 and GL-4 applications, as well as where most special synchromesh fluids are specified.
•Satisfies the gear oil viscosity requirements of 75W90, 80W90, 90 and motor oil viscosities of SAE 40, 10W40 and 15W40
Unfortunately its $25.00 CAD/liter as it is a synthetic.....but shift feel is fantastic.
if you have found a cheaper, safe & local (Canadian sourced) alternative please let me know as its not stated in your post.
Regards to both...
