Trail Boss 10L80 PPE Transmission Pan Install

[WrenchingMafia]

Hey everyone, I just did a transmission pan drop and fluid service on my Trail Boss with the 10L80. Wanted to share because I know a lot of people are unsure about servicing these. I replaced the pan/filter assembly and refilled using the proper temp check procedure. The fluid condition wasn’t terrible, but I’m glad I did it for preventive maintenance.

I filmed the whole process including removing the pan, what the fluid looked like, and checking the level between 167°F–176°F with the engine running. It’s definitely doable at home if you take your time.

I installed the same! Great pan since now we can do at least an easy no mess drain since it has a dedicated plug.

A little bit of an issue. I had to drop the Y-pipe and in order to do so, I had to remove the exhaust flange bolts and Bank 1 Sensor 1 and Bank 2 Sensor 1 O2 sensors. In order to remove the old pan and install the PPE, I definitely needed to remove the flange bolts to drop the Y-pipe. I only removed the sensors because I didn't want to take the chance of breaking a connection.
