#1) Should NEVER flush your honda AT.
#2) ONLY USE HONDA ATF
#3) Jiffy Lube sucks!!!!!!!!

Most likely your transmission is done. I just did a drain/fill on my 98 V6 accord 2 weeks ago. Jack the car up and there is a 3/8 socket wrench bolt on the tranny. Loosen that up and let it drain out.

Do you have the 4cyl or V6? If 4cyl you will fill it up through your tranny dipstick, if it's a V6 like mine there is a large bolt marked "ATF" if you look right over your intake tube. Drain and fill 2-3 times but not sure if that'll help your tranny as it's probably done.
