I have an Accord V6 3.0l with an automatic transmission. A few weeks ago, it started to make the shifts in an abrupt manner, as if it had no torque converter. A few weeks after, the transmission slipped whenever I put my feet off the gas. I drove the car as if it where a “manual” transmission, making the shifts myself. Then I lost 2nd. Gear, so I shift 1st., and stay there until I was going about 30 miles, then shift to 3rd and 4th gear. Now the transmission knob blocks when I put it in Park, so I have to unblock it with a key. The scanner reports no codes. Any idea on what is going on? I understand the B7XA transmission is sadly famous for being a piece of trash. Thank you.

P.S. Excuse my english, I'm from Mexico!
