[TR] TR3A Overdrive Question

[Jim Henningsen]

Want to fix a leak on my 61 TR3A od gearbox on the OD brass plug.  It only
has 400+ miles since it was rebuilt, but they do like to leak.  Drained oil,
removed OD brass plug with 1 3/16 hex nut fitted.   Any recommendations on
best way to seal that brass plug?  The fiber washer for the sealing plug was
new when rebuilt and looks great.    Also, any recommendations on using
Valvoline VR 50w racing oil in tranny instead of the normal stuff? Heard
that was an option that worked well.
Thanks in advance?
