tranny oil Posted by Kevin K [Email] ![]() ![]() In Reply to: Kevin K.....Thank you, Terry Meitz, Thu, 22 Feb 2001 23:14:17 Members do not see ads below this line. - Help Keep This Site Online - Signup |
compressor oil has no detergents, and is prefered flush. 20W is best for you as flush, but 30W is ok too ...... these usually carry an API 'SA' label. This is not the same as 20W, or 30W motor oil, which is SJ or SH rated and has detergents. This trans flush is my suggested step in switching fom one synth (or unknown)to another synth, knowing synthetic chemistry can vary widely.
20-50 amsoil is townsend's prefered (not for very cold climates). But re-reading their info, they 'imply' not to use it if any gear oil (stinky) was last run in the box. So smell what you got 1st.
Townsend has lots of good info, but I don't know enough about their test data to blindly agree with their conclusions. Valid logic is some metalic wear sediment is freed by the detergents, thus gear-oil to motor oil could increase wear rate. But then I question where is the pump and filter system to remove normal, suspended wear debris if motor oil is used?
My suggestion for you is if it stinks, go with the neo gear oil I use.
In general, I prefer modern synthetic gear oils .... for gears! MTL and honda MTF are both GL4 gear oils designed for smooth shifting, and fine for most people, and prefered for the extreme cold climates. Neo 75-90HD is a heavier, tougher GL5 gear oil for higher power levels, or mabe extemely hot climates. Redline 75-90NS is a GL5 that crunches syncros.
thanks for the thanks .... should be some new faq's on this stuff before too long.
