I just bought a 2015 Expedition xlt with 175,000 miles and wanted to start fresh with all new fluids. My local shop said they would not touch the transmission unless it has been drained/filled in the past. They expect me to keep driving on the old fluid.
Is this a thing, where if the fluid possibly wasn’t changed in the past, the new fluid now will now make the transmission inoperable, as this shop suggests? Or do I need to find a new shop?
Normally I do all my own wrenching, but it’s winter and I’m not crawling under my truck now. We are taking a family trip to Disney in 2 weeks, so that why I asked the shop to do it. Had it been summer, I would have done it myself already, because I have never heard of new fluid screwing up a transmission before.
So, is that a myth or should I be concerned?
