I agree, thanks for pointing that out to readers. Some transmissions failed under warranty in the rare cases where the owners switched to non-approved fluids with very low miles. Some autocrossers change tranny fluids when a car is only a few months old, so my buddy got burned. It eventually got to the point that the OEM was denying warranty claims when the fluid color was wrong while applying legal pressure to the lubricant manufacturer who was recommending the use of non-approved fluids. This happened at both Ford and Toyota. However many trannys didn't die until a decade or so due to many variables, including the point in time when the owner elected to switch to the unapproved fluid. Some people don't try alternate fluids until a vehicle is many years old. For this reason failure trends are very hard to uncover. Many owners were eventually affected. Some folks remained in denial for years until evidence became overwhelming. Then panic set in.
