Thanks for the pics were those trannies in a gas or diesel engine? the trans in huge ! 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.

No it has not. It makes too much sense to do that. 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!

I can't believe that person is still employed. 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!

Great info - thanks for posting. Will be ordering another filter and Mercon LV tomorrow for my 6R140W, based on the comments above. Has 155K, but haven't replaced filter or drained since 75K.

Definitely do so. These are not the cheapest units to rebuild. 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?

What year is your truck? 2014 F250 6.7 (20-30% of the miles towing 14K). Thanks for the advice!

The 14s have most but not all the updated hard parts so if you ever have to have it rebuilt not too many updates other than replacing worn parts
When it starts to show issues it will usually start flaring shifting from 3-4 so just watch for that.
Is the truck tuned/deleted?
