Slipping O/D

[A666K@aol.com]

Hey all,
The other day I noticed the O/D slips under hard accel. in 2nd, especially 
when colder. I recently put in RedLine MT-90 fluid, and suspect that is the 
problem. Checked the archives and saw a survey done on O/D fluids, but 
couldn't find a conclusion (Joe?). There was mention about fluids causing 
slipping though. A friend with a Jtype O/D but in a TR6 claims slipping using 
of Hypoid 90 gear oil. Any recommendations in general? Anybody else using a 
RedLine product in a Jtype O/D?
TIA,
Avi
