Daughter has 2018 Honda accord hybrid with push button transmission that needs transmission fluid change . the car is new to me so i watched videos . one is a 2018 hybrid and shows simply draining at drain plug and replacing with 2 1/4 qts fluid at fill port on top ....the other is a 2019 (that specifies push button trans) with this one he used a pump setup under the car to refill. My question do all 2018 accord hybrids have push button transmission and . why is there such a difference in refilling the transmission between the 2018 and 2019? Thanks for your comments
