Well I just bought an acura tl type-s a few months back with a little over 100k miles on it and I think the tranny is toast. Yesterday it began slipping and today on my way home the D5 light began flashing. I pulled over to make a phone call and when I put it in drive the car stayed in first gear and wouldn't take reverse. I don't really know much about these cars right now but any help would be much appreciated. Thanks

 

Forgot to mention it's an 03
