2013 Peace, mercy, and blessings of God be upon you. Dear brothers, I have a question and I hope you can help me. I have a Camry model 2013. It rained in Abha, and afterwards, the transmission got messed up while I was driving at 110 km/h. It shifted back to 2nd gear, and the check engine light came on. I stopped the car immediately and left it until the next day. I started the car, and the check engine light disappeared, and the gears returned to normal, thank God. However, reverse gear developed an abnormal jolt, making it feel like the engine is about to come out of its place. I went to several workshops, and of course, right after the jolt appeared, I changed the transmission oil with half a bottle of green Toyota oil. But it did not disappear. I went to several diagnostic centers and workshops. Each one suggests a different problem. So, good people, we need your advice. May God reward you.
