I'm not entirely sure, but the use of Redline MTL might not be
compatible with the overdrive since the overdrive relies on friction of
a cone shaped clutch to stay engaged. If the Redline oil is to
slippery, it might cause the overdrive to slip when it's engaged. I'd
check with others on the list to see if they have successfully used this
in their trannies.
Let me know.
