I have a 2004 Honda Accord sedan, automatic transmission with about 180k. I wanted to get a second opinion on what I'm observing to see if there's a problem (which I think might be starting) or if there's nothing to worry about.
Yesterday while driving on the freeway up a mountain (posted speed is 55MPH and I was going about 60MPH but slowing down due to the mountain), I let up on the gas b/c someone signaled to get into my lane. After they merged in, I pressed the gas to keep my current speed. However, the engine acted like it was switched to neutral, in that when I pressed on the gas, the engine revved but it didn't go anywhere. I let go and pressed again, and this time, I felt my car get pulled by the engine. I don't think I pressed the pedal that hard the first time so I don't know why it revved high, other than my transmission is starting to have problems.
The second incident occurred about 1 wk ago while driving down an expressway (posted speed is 45-50MPH but there are traffic lights). I was going about 35-40MPH. Traffic started to open up a little so I was accelerating up to 50MPH. However, it seemed like the car didn't switch gears. I could hear it rev high but I think the car was still being pulled by the engine/moving. I let go of the gas and pressed again and this time, it seemed like the gear switched in that it didn't rev high.
I don't consider myself an aggressive driver (no jack rabbit starts, no flooring the gas pedal, no hard braking, etc.) and I don't remember these things happening before so when it happens while driving, it's a little scary.
Are these 2 events an indication of my transmission starting to go out or am I just being an alarmist?
