They can never be re-titled and must dismantled. ALL the vehicles taken out of service were kept in 100% working, operating condition. This transmission fits many applications. NOW, when it comes time for City Council to strike a deal swap out the fleet of 500 or so, old ones are taken service, and new roll in.

So we got all the licences needed to purchase these write offs. EXAMPLE, when the Ford dealer writes up a $32,000 estimate of repairs, Fire Chief gives them go ahead and these Trucks get pampered. Allison 1000 Transmission PTO capable WITH 120,000 MILES ONLY. Now heres where it gets good.

NOPE, out of service they go. Warranty covers parts only.
