Flush Transmission???

Dump and fill. Drive a week. Do it again. Repeat 3-4 times you’ll have it mostly turned over

 

I agree with the concept. But 3-4 times x 4 quarts x $10 = $120-$160. What would it cost to have the dealer do it with a machine and call it done?

 

I use valvoline maxlife aft. 20$ for a gallon. 3 drain and fills is 60 bucks. I only suggested 3-4 because OP has 115k miles on his fluid and thinks it is all original. I did 2 drains at 60k and 2 more at 95k miles myself.
