Ok, I need a little help. My 01 accord seems to be acting funny. When ever I accelerate my car shifts a liitle hard. Sometimes it will punch in hard, like I floored it or sometimes seems as if it redlines long then shifts. It only realy does this around 1st and 2nd. When the hard shit thing happens it's not like a bang, my car just takes off real quick. I had my transmission flushed a few months ago and it helped a bit, my car has about 150k, and this was the first time I flushed it. The guy told me that I might have to do it again cause of the build up possibility. I also have not changed my timing belt yet, could that be the prob? Or maybe a tune up?
