Sidegear

Tuff Torq Corporation, has discovered that a small number of transmissions were manufactured with a differential side gear, 168T20-31560, that does not meet specifications.  While the chances are low, this could lead to premature failure of the gear early in the life of the transaxle, resulting in possible loss of propulsion and braking. Because of this issue, any transmission issues caused by the failure of differential side gear 168T20-31560 should be replaced at no cost to the customer regardless of the warranty period.

If there is a failure, it will only be in the models and serial number ranges listed on the pdf link below for products built for US manufacturers.
