I have a 03 at coupe the reverse on the tranny is acting up it wont go in gear unless I rev it up I haven't had any previous problems with it I checked tranny fluid it was full and was change about 1.5 years ago shows to be a little high. it does seen that when I put in reverse It barely grabs the gear cause it slowly moves backward at idle. Any suggestions would be appreciated.

 

I have read the tranny in this year isnt good would like suggestions if i should have tranny rebuilt or buy a new one. If so any suggestions where to buy one at
