Heyo, I don't have a transmission for sale but I can give you insight about the ASU5 transmission (TSX). Heres what I told other members:
"The ASU5 transmission is known to 'warp' by excessive heat where the input shaft bearings holds and the transmission case cannot be fixed because the transmission is made out of magnesium instead of aluminum. Another alternative to the ASU5 transmission would be the ASP3 off of an Accord Euro R and it is a direct fitment. Just wanted to warn you about it if you havent heard about it."
