Recall 23V459 affects 163 2022-2023 E-One Typhoon N, Cyclone Ii, and Cyclone N vehicles for defective transmission coolers. Free repair at a franchised E-One dealer.
E-One is recalling 163 2022-2023 Typhoon N, Cyclone Ii, and Cyclone N vehicles because an insufficient weld in the transmission cooler can let engine coolant contaminate the transmission fluid. Contaminated fluid can lead to transmission failure and loss of drive power, which increases crash risk, and E-One dealers will complete the free repair.

What's wrong?
The transmission cooler on the 2022-2023 E-One Typhoon N, Cyclone Ii, and Cyclone N is a heat exchanger for the automatic transmission. Transmission fluid moves through it so heat can transfer into the engine cooling system and keep the transmission fluid within its working range. The cooler has to keep engine coolant and transmission fluid separated.
In campaign 23V459, the internal welds on the transmission cooler were not completed tightly enough. That weld problem lets engine coolant enter the transmission fluid. Once coolant contaminates the transmission fluid, the fluid no longer protects the transmission as designed, and the truck can develop shifting problems like the vehicle E-One investigated before the recall.
The warning sign is discolored transmission fluid. If service personnel see fluid that does not look normal, treat it as a sign that coolant has mixed with the transmission fluid and contact an E-One dealer for the recall repair.

What's the safety risk?
Contaminated transmission fluid raises the risk of transmission failure and loss of drive power, which increases crash risk. Discolored transmission fluid is the warning sign. If you see discolored fluid during a check, stop using the vehicle until the dealer advises you. Repair is free at any franchised E-One dealer.

- Bring the owner letter if you have it. If not, reference recall number 23V459 when you call.
