17 transmission slipping after up to temp

[sixshooter_45]

When I asked my Dealer, a large Ford Dealership, how they change the transmission fluid they replied we flush it right through the cooler lines because that's the best way.

I laughed and told him of potential issues doing it this way.

He stated that's how I do it on my own truck and we've never had any issues.

My question is why in the hell do these so called professionals screw up a simple procedure, I know, because of expediency but it's still ridiculous to ruin customer's vehicle because of their arrogance & stupidity.

Ford should have the oversight and authority to stop Dealers from doing improper procedures as it would benefit Ford, the Dealership and customer.

Same here. My service dealer, who I really like, wanted to service it this summer when I was in for my cam phasers. I asked drain and fill? No we flush it. They failed my quiz. I said no thanks. I knew better. It’s hydraulic fluid with lubricants, if it ain’t burnt, it ain’t bad.

I wonder how you over fill a transmission if you first bring it up to the specified operating temperature, shift it through all the gear positions, hopefully leaving it in Park. Then on the transmission (vehicle passenger side), un-screw that little filler cap, remove the mini plastic dipstick and check the level. All with the motor running and again transmission fully up to temperature.

It took my 3.5 EB & 10 speed transmission several miles before its transmission came up to the recommended stable temperature on a hot summer day. I could see the transmission temp vary up and down as its thermostat cycled during the warm up and it finally stabilized at the required temperature. I was pleasantly supersized the factory's fill was right on the mark.

The answer is that flushes are highly profitable for the service department and service advisor. The flush equipment is typically provided for free by companies like BG, who then make the money back through the sale of the flush chemicals.

We all wish. The problem is dealerships are “Independently owned and operated”, and they have powerful lobbyist groups. They care about what it profitable for them, not necessarily what is best for the customer or the OEM. The OEM typically can only control warranty related issues, either by chargebacks or audits, both of which are reactive instead of proactive. This is the same reason dealers get away with installing aftermarket lift kits and alarm systems in brand new vehicles; once the vehicle in in their possession, the manufacturer has little control.

Unfortunately I was unaware of this. Dealership recommended it to me as of higher mileage. They did oil, trans, diffs. I was unaware and even have an email asking if it is recommended.
