Since 1986 AL Trans Service, Inc. has been serving the Allison Transmission market along the Gulf Coast. We are an Authorized Overhaul Dealer for the Allison 1000, 2000, 3000 and 4000 Series Transmissions. Being an “Overhaul” dealer means we can perform any Allison Warranty repair needed unlike a “Maintenance” dealer.
