I have a 2006 automatic. I had a issue with rough start off and rough shifting first to second. I replaced the shift solenoid for 1-2 and 3-4. I got everything back together and topped off the fluid. I started the car and shifted into each selection and paused. I did this sever times. I then Slightly reved the engine for each selection. I never got the jolt with the car going j to any gear. Now when the car comes out of park it acts like it's on neutral. Any suggestions on what I may have missed or to check?
