I noticed my car would forcefully engage when entering the third gear, and it would trigger the engine to stop revving and accelerating until I put off the engine and start it again.
I Have changed the throttle sensor, the throttle body and the gearbox as wel, yet I still notice that it engages the third gear forcefully occasionally and do still trigger it to stop revving and accelerating.

Please what do I do?

My Camry does not run smoothly.It is worse when I have to put on the air conditioning. Once I put on the air-conditioning, it will drag to accelerate and eventually kill the engine completely. I would have to turn off AC and restart the car. How can I repair it?
