FEATURE Fleet Maintenance Tips
service procedures; however, they caution regardless of maintenance, the life of a CVPI transmission is limited to about 100,000 miles in police service. On the other side of the coin, Chrysler recently issued TSB #D-12-
24, which addresses the routine practice of engine, transmission, power steering, and air-conditioning system flushing, which are strongly ad- vocated by various “quick-lube” operations. Chrysler’s position is these components do not normally need to be flushed. Te exception to this would be if or when a component failed. Ten housings, hoses and coolers should be flushed prior to re-assembly.
The Peugeot 308 is a widely used police vehicle, but the star of the show was the 508 diesel hybrid hatchback.
Trans Flush Not all fleet maintenance facilities can afford a fluid flushing machine, and Mike Bruno, a police mechanic for the Highland Park (Ill.) Po- lice Department came up with a cost-effective method of completely changing fluids in their later Crown Vics. Tis process utilizes a 5-gallon bucket, hose clamp, and 6 feet of plastic tubing. Te cooling line from the transmission is disconnected at the cooler and the length of plastic tubing is secured to the disconnected line with the hose clamp, the other end of the tube being placed in the bucket. Remove the dipstick and insert a funnel into the fill tube. Start the
engine and slowly add 12 quarts of A.T.F. into the trans—at about the rate the old fluid is coming out. When fresh fluid starts coming out of the hose, the old fluid has been purged. Stop the engine and reconnect the cooler line to the cooler, add enough A.T.F. to top off the trans,
check for leaks, and road-test. For additional insurance, they install Ford’s in-line filter (P/N #XC3Z-7B155-CA). Tis filter is really a rebadged Magnefine unit, which contains a 35-micron filter and a magnet to help trap ferrous matter sloughed off from the planetary gears along with other trash, which was not trapped by the filter in the pan.
Full Synthetic Te City of La Habra, Calif. used to average about 65,000 miles before transmission failure occurred on their police vehicles, even though they received the recommended transmission service every 30,000 miles. Mark Compton, the city’s fleet manager, switched to a full-synthetic ATF (Dextron VI) that lengthened trans life an additional 30,000 miles. With the upgraded oil, transmission life is now extended toward the 100,000-mile mark. If major transmission problems do occur, La Habra Fleet Services will exchange the offending unit with a genuine Ford remanufactured unit, which has all the latest upgrades and is backed by the factory warranty. Many of our newer transmissions do not have dipsticks, thus the computer monitors the fluid level. Servicing these newer transmissions now requires a scan-tool, a subtle reminder that transmission servicing should be conducted by a properly trained technician. Paul Condran, Equipment Maintenance Manager for Culver City,
Calif. is an advocate of Pure-Power Oil Filters (www.gopurepower. com). Tese reusable filters can be disassembled, cleaned using a parts
The Vauxhall (GM) Ampera and Insignia are increasingly important to U.K. police fl eets.
