Defect: Maintainer Corporation of Iowa, Inc. (Maintainer) is recalling certain modified 2019-2020 International CV 515 and Chevrolet Silverado tow vehicles equipped with Allison 2700 series transmissions with Chelsea Power Take Offs (PTO). The PTOs were installed incorrectly and as a result, the attachment hardware may loosen over time.
Risk: If the PTO attachment hardware loosens it could cause a loss of transmission fluid which may result in the rear wheel locking up, increasing the risk of a crash.
Fix: Maintainer will notify owners, and dealers will inspect the PTO and install a new attachment stud kit, free of charge. The recall began June 9, 2020. Owners may contact Maintainer customer service at 1-800-831-8588.

Technical service bulletins are repair instructions manufacturers send dealers for known issues. Unlike recalls, the fix is not automatically free — but naming the bulletin at the service desk can save diagnosis time and support goodwill repairs.
