The official notice
Defect
Certain operating conditions can result in heat build-up between the countershaft and secondary shaft second gears in the automatic transmission, eventually leading to gear tooth chipping or, in very rare cases, gear breakage can occur. Gear failure could result in transmission lock-up.
Safety Risk
No risk description available.
Remedy
On vehicles with 24 000 kms or less, the dealer will update the transmission with a simple revision to the oil cooler return line to increase lubrication to second gear. On vehicles with more than 24 000 kms, the dealer will inspect the transmission to identify gears that have already experienced discoloration due to overheating. If discolouration exists, the transmission will be replaced. If discolouration is not present, the dealer will perform the revision to the oil cooler return line.
