Transmission Not Engage Problems of Mazda CX-5

Since last recall repair my Cx-5 is experiencing major problems. It will randomly not start. I get in and depress brake pedal, but start button will not light green and car won't start, even after changing battery in key fob. The dashboard lights (all of them) will come on and flash, then go away. The other issue is that the transmission will not engage after car has started. Car is started and in park. I depress the brake and try to put the car into gear (drive) but the shifter refuses to move at all. Pumping the brake does not work, depressing the brake all the way to the floor does not work. There is not a particular sequence of actions that will get the car to go into gear. The only remedy I have found is to turn the car off and let it sit for an extended period of time. When driving the car after this has happened, if I use reverse and then put it into drive, the car jumps forward without my foot being on the gas pedal and then the lights on the dashboard for tire and tcs come on.

Vehicle would not engage in drive when shifted into drive. There was a 3-5 second delay and the engine would rev, but the vehicle would not move. When the vehicle did engage in drive it would pull forward hard and clunk into gear.

First experienced the problem two days ago, shift the gear from parked position to reverse but the gear failed to engage immediately; then shift the gear to drive again gear failed to engage immediately for 3 or 4 seconds then sudden jerk when gear engaged vehicle starts to move forward (luckily did not step hard on the accelerator and rev the rpm). Same problem happened on highway speed with either acceleration/deceleration where rpm rev from approx. 2500rpm surge to 4500/5000rpm then experienced strong jerk. Also, when vehicle stopped at signal (longer stop) gear in drive position seems to disengage and same problem occurs. Vehicle left at Mazda dealership and checked by Mazda service mechanic awaiting for their investigation.

Driving on a side street, I felt a clunk through the gas pedal and the rpm's nosed dived to around 1500. Snailed it over to the shoulder, put in park, stepping on the gas would rev up to 2000 then drop to 1500 on it's own regardless of gas peddle position. In park, shut off, restarted, lots of pretty lights on the dash (at, tire pressure, engine, traction control, plus others), no change, rpm to 2000 then drop to 1500. Still in park, shut down, restarted again, rpm's were normal but no forward gears in auto or auto-manual (could shift to 'd' or +/- but wouldn't engage). While in 'd' was able to rev engine but transmission obviously not engaged at all. Reverse worked fine, shifted back to 'd' but still no response. Check engine light on. Shut down a 3rd time and restarted. Check engine on but rpm and transmission normal. Drove to dealer and dropped it off. Service dept. Called later to say ordering a valve body for transmission.
