I think I have to back to regular dex/mercon fluid, what do you guy recomment ? I drive my car year round.
Did you hear this on the LS1Tech forums??
I
used to believe this as well (at least for the 'paper' [actually cellulose composite], NON-carbon fiber blocker rings), and also fell prey to all of the warnings and hype on the LS1 forums.
But then some of the most reputable T56 rebuilders in the country (world??) started suggesting Mobil 1 ATF, as well as other synthetics (even in stock, un-rebuilt, not upgraded with the cf blocker rings, T56es) for use in our gearboxes.
Late model domestic musclecar autocross guru extraodinaire, Sam Strano has used Redline D4 in the stock, unrebuilt, older model, T56 of a daily driven, 275K+ mile E Street Prepared national title winning LS1 Z28 for the last 12+ years with NO ill effects.
So I put this stuff in and NEVER looked back (except for sometimes switching to RL MTL in the hotter summer weather).
I DID
NOT have to ("look back") as it has been perfect ever since!!
If you press them long enough, even the techs at Tremec will admit that the Mobil 1 stuff is A OK in the 'paper' ringed T56es (as they did to me).
YOU HAVE
NO WORRIES WHATSOEVER!!
AFAIK, Borg Warner makes the T56.
They did make the early, original T56es, but production/copyrights/etc. was sold/switched to Tremec.
I'm not exactly sure
when this happened, but I'm going to guess around '98-'99, so yes, CamaroT56's gearbox may very well have been made by BW.
