So I bought my 2010 EX sedan last February with 89k and after about a week of owning it I noticed it wasn't shifting into 4th gear on a cold morning. This made it overheat and it didn't smell very good. I took it into Honda right away and they said the fluid was low and dirty. So they drained and filled it with new fluid. It's been running fine for the most part all year but since I started having trouble with it I notice it shifts a little harder than my girlfriends 2010 LX. Since the weather has gone below freezing here in Maine, it's been giving me trouble again. Even if I let it warm up for a good 10, even 15 minutes it will still not shift into 4th until I get about a mile down the road. As it warms up I can literally feel the gas pedal loosen up. It'll have a stiff feeling at first. So basically I have to drive it to warm up the transmission. This car has been scanned by 2 garages, has no dash lights, and isn't leaking. It's been taken to the Honda garage and a transmission specialist a few times. Recently I was at the Honda garage again and they said the fluid wasn't low but burned, so they wanted to drain and fill it again and filter the fluid to see if they find metal shards which would indicate the problem. I heard you can check for metal shards on the dipstick if it really had that issue, I think they're just trying to get money. Since I just had this procedure done last spring, I opted out of that since it would have been $390. That's a lot of money to spend just to find out if my transmission is bad, especially since if that was the case I would need that money for a new transmission! The fluid should be changed again, but my thing is..I'm thinking its already screwed anyways so what's the sense? My car hasn't acted up on the mechanics even after being left overnight so no one but me has experienced it. Maybe that isn't helping my situation. But they even said by my story it sounds like it could be going out. I asked could it be a solenoid? They don't think so. Anyways, I figured I'd come to this forum and ask the real experts of these cars to see if maybe someone knows what this extremely frustrating prolonged issue is. I'm getting really tired of wondering, about ready to trade it in. I love the car though and it only has 100k. Is it time for a new transmission? I've been some money into this car and still owe money on it so I'm really on the fence on what to do here.....thoughts? I would appreciate it greatly! Thank You
