I'm wrapping up a ground up resto on a 69 SS. Converted from an Auto to a TKO500 and will ready to crank it up later today. Rushed off to the Chevy dealer and asked for the Synchromesh tranny fluid. Got home and found out the fluid I bought is the Friction Modified version part #12377916. Being that Part #12345349 is the version called for my question is this... Try the 12377916, or use the penzoil or 12345349 syncro fluid in the Camaro , and try the 12377916 in my `07 5speed mustang and probably enjoy much better shifting over the mercon in it now. Or maybe somebody out there has tried the friction modified version and can advise. Thanks...Awsome site I might add.
