I have an '11 coupe (EX-L) with manual 6 sp and nav. Bought it used with 3k miles and just found out the transmission was replaced at 1k miles due to being noisy. It has 6k on it now and reminds me of the manual tranny in my F-250 Ford Super Duty Diesel. It whines in 6th, and is not smooth shifting, especially going into sixth. I haven't driven another, but wonder if I can get some input from other owners of same equipped coupes? Thanks!

 

I don't have that car, but I'll move this over to General Tech where you'll more likely get answers.
