Just bought a civic and the day i get it 3rd suddenly decides it likes to grind over 3500rpm now
I changed the tranny fluid and the problem still persists although it does not do it upon downshift. The car has a b18b1 block with a sir flywheel and sir s4c tranny. I am going to have to borrow money to get this fixed so the cheapest solution would be best

. I have been quoted 1300+ to rebuild it so im guessing a used tranny would be my best bet, any ideas where to start or what i could throw in?
