He refered to it looking like "taffy" slinging around in there.
I thought GM was nuts back in the mid 80's when they told us to put 15-40w motor oil in S-10 blazer/pick up 4WD transmissions, in retrospect, as long as the seals were able to handle the motor oil this was acceptable, but 50 W tranz oil? thats just crazy. but wait, the warranty says it all, if you have an engine failure you MUST return your engine for warranty inspection. lol.
