Top Plow Truck Transmission Repairs & Upgrades

Heavy snow storms, sub-zero temps, and black ice are a few of old man winter’s favorite tricks…and can lead to treacherous driving conditions. Working hard to keep roads safe, plow trucks often burn through transmissions and end up in the shop.

Check out these top Sonnax transmission repairs and upgrades to get them back on the road and going strong before the next storm hits. You can select individual parts and kits for a custom rebuild, or choose a premium remanufactured valve body. Either way, we’ve got you covered with top-quality solutions you can count on.
