Both gas and diesel. Is your shop seeing many of the 60R140 trans with problems? I am a fluid and filter changer when the unit is new then sooner than later after the break in oil change None that I have seen. But we generally don't repair something like OP does, they just have us put in a new/reman assembly. 2014 Ford Mustang GT Track Pack 1995 Ford Mustang GT Ford/Mazda Parts Counter NRA Benefactor Member Opinions expressed are my own.

The person that is in charge of the department does not believe in routine fluid changes (other than engine oil). I have convinced him otherwise as this is the 7th transmission failure in 2 years in rescue fleet alone. Not really surprising. They think they are saving money buy not doing proper preventitive maintenance till something grenades and ends up costing them big bucks. I can imagine these transmissions are not cheap to rebuild and the downtime of not having the vehicle in service can be detrimental for an emergency services outfit. It is good to know you have convinced them otherwise! 2015 RAM SXT Crew Cab 5.7 with 6 speed tranny. 2008 Mazda 3 GS Sport Hatchback 5sp MT (Girlfriend's car)

On fleet trucks the only real way to keep them on the road (and hence, making money) is to do preventive maintenance. I had a buddy that owned about ten semis that hauled steel in the NW Indiana area on local routes, so a couple loads per day loaded to the max weight limit of the roads. He said that a single day of not hauling loads on a single semi ended up costing him around $300-350 in lost income, AFTER all the bills and payrolls were paid. Tell me any normal maintenance such as oil and trans fluid changes that will cost a business owner that does their own maintenance that much?? Now, add a trans rebuild and multiple downtime days together because of skimping on preventive maintenance... $15-20k realized loss to the business easily. Per truck. Adds up quick!

Due to the service the trucks I work on see I convinced the boss that to do a drain and fill once a year on all the trucks. What year is your truck?

Is the truck tuned/deleted? Last edited by mattd; 02/06/19 06:23 AM. 2007 Ford F-350 4x4 6.0 PSD ASE Master, L1
