yes, i wonder how the trans will behave with the higher viscosity. surprisingly amsoil specifically recommends it.I have not but Amsoil ATF and Redline D4 are closer to the specified viscosity of about 7.2 cSt.
thank you.
i still wonder if anybody has experience with amsoil synchromesh (49.4/10.1/196) i the T56. it seems pretty thick at 40°c.
is anybody running amsoil "manual synchromesh transmission fluid" (mtfqt) in a t-56?
What exactly did you ask?yes, pre 1999 (out of memory) units were reported to have problems with the cellulose binder. t56 in question is 2007 c6zo6.
i would hate to experience notchy shifting until the oil heats up (happens fast, but anyway). asked amsoil twice, but got no reply. i guess they recommend it and dont discuss it further.
