Ughhhh! Transmission Puked Fluid AGAIN!

[Glocker]

Back in February 2025, I posted about an experience coming home from the beach on an hour drive home on the highway, and the transmission seeming to wig out, bang hard, and there being a smell of hot transmission fluid. When I got out of the truck, just off the interstate, I found there was transmission fluid all over.

I had a service done on the truck some time before that, but hadn't really driven it that much, and there was a belief that the pan may have been overfilled. The dealership said they believe it had "just burped" and the fluid levels were looking okay.

Fast forward to this morning! I had to get up early and take the wife 30 minutes down the road to the airport, on I-95. No issues. I took the turnpike back north to the house, and when I went to go pass someone, accelerating from 80 to 85, it felt like the truck was hitting a rev limiter and retarding ignition. It just felt like it didn't want to go.

I got to the house, and smelled hot transmission fluid. Ughhhh.

Once it was daylight, I went back out to the truck and there is fluid all over under there. Mostly under the transmission cross member, but also around the pan, and you can see where it has just blow all under the truck, starting from the sway bar back. There are also a couple of drips on the ground.

Damn. I don't know what to do next. This is awesome - my extended warranty ended this past May!!!!!! HAHAHAHAHAH! Of course!

I think that it was still overfilled and is only venting the fluid when you do long drives and get the transmission temperature high. If it is overfilled, it will foam when hot and vent. The foaming fluid will also cause the seemingly lack of power that you experienced.

Don't trust the dealer to get fluid level right , got mine back, 1 1/4 quart to full.
