I Overhauled the 2002 CIVIC Auto Transmission step on it and it shifts great no leaks gets good gas mileage 2 weeks of sweat. The only trouble I have is when I almost stop but still rolling step on gas and BOOM it drops into gear just like you drop the clutch! if you stop works great shifts great I went over the everything I did in the overhaul no extra or left over parts. Do I need to do anything with the COMPUTER? re program.
