I have a 2008 Honda Accord with an automatic transmission. I don't know much about cars. The car seems to be having problems switching gears, especially in low gear. For example, often when I'm accelerating from a stop, things will go fine at first and then once I've gained a little bit of speed the engine will seem to rev for a while before switching into the next gear. Sometimes taking my foot off the accelerator will help it along, but this doesn't always work, either. It's possible the transmission is slipping into neutral, but I think power is still going to the engine, even when it's rev-ing. The transmission doesn't seem to have the problem at higher speeds.
I've already had it checked out by a mechanic and they recommended I repair the transmission, which would cost $4K. They didn't seem too sure about it though and it makes me think the problem may not be so serious.
What do others think? Is this a serious problem? Is there anything I can do to work around it without actually needing to repair the transmission?
