This 2008 CX-9 GT is a friend of mines. He asked me to replace front passenger CV axle. (completed). I started engine put in drive..went thru gears..no problem. When I put it in Reverse...ALOT of screeching noises from the tranny. I am not a transmission guy, by no means. But if fluid level is ok, drive is ok...reverse has a BIG issue. More than likely...he needs a transmission. Wouldn't you think??.
