I bought my 93 Camry brand new and ever since it had a few minor fixes, otherwise running smooth and is in good condition. The problem just started last week. While I was waiting for the train passed, I turned of my engine and when I re-started it, the car body especially the heading was throttle a few seconds then started running as normal. This is the first time it happened. After driving for 15 mins, the car started slowing down and stopped moving but the engine was running and the Tachometer at 3/4 just as if the car was on brake and I accelerated it. So I had stopped and re-started the engine, then the car moved. It was working as normal for a few days, and then problem started again. In addition to that, every time I stopped at the red lights, the engine was running but the car stopped moving. Turned off the engine and re-started then the car moved. The problem repeated frequently especially driving for an hour or more. I also noticed if I turned on the air-condition, the problem started quicker. I brought my car to the mechanic and he said the problem was the transmission. He changed the fluid, filter, etc...and told me if the problem still occurs; I have to replace the transmission. It will cost me approximately $1,500 (used one). After fluid changed, the car running as normal for a couple days, then problem started again (if driving
15-20 mins, the car is fine). I am an automobile illiterate. I need your opinions what could be the problem, fix, cost, etc... Please help.Thanks and Regards, Mike
