Had my 8l90 overfilled apparently

Recommended Posts

Just did another drain and fill on my 19 cc z71 8l90 last night. Measured what came out and refilled…. This morning I decided to do the fluid check procedure.


Between 95F  tranny temp and 113F on level ground I opened the overflow plug at around 104F and let drain what comes out to make sure level is correct etc.


2 quarts drained back out and then it came to a small drip. Been driving like this for the last at least 20k miles since I did drain and fills a couple times already before. trucks never shifted bad or anything. Found this interesting though apparently being overfilled 2 quarts.  My thermostat is flipped btw not sure if that changes anything on the procedure.
