2 Parts: 1. Shifting into Drive after the Engine warms up it thumps and jumps into drive. When cold it shifts smoothly. However, it doesn't happen all the time. 2. Car shuts down randomly while driving. As if someone pulled the key. On my display I get A. Gearbox Malfunction B. Traction Control Failure, and C. Stability Control Failure. I have been dealing with this since the beginning of the summer and I don't know what to do anymore. However I did do the following: Replaced the Ignition/Starter Relay, Replaced the CPS, Replaced the Motor Mounts. Motor Mounts have noticably imporved the ride, but I still Shut Down while driving and the thumping jerking when shifting into D is still there. Please help or any guidance from an expert. I am so done.
Thank you.
Kris

Have a trans guy run a scan on it to see if it's electrical or internal problem. Check your fuel pressure it should be 43psi with.7L in 30 seconds. It may be a speed sensor, but you shold have a check engine light on so codes should be present to see what the problem is.
