Hello Guys..
I have recently changed Automatic Transmission of my Honda Accord 1995. Bought a MP0A Transmission from a junkyard (It may be lying there for some time, maybe). I am facing 2 problems:

1. When i put car in D4, sometimes it goes directly in 2nd gear with a Jerk. Also it wont shift further into 3rd gear unless i release gas pedal. once i do that, it shifts into 3rd gear wiith a huge jerk. same happens for 4rth gear

2. It does not down shift even if you stop the car. if a manually downshift using shifter then it shifts down with a jerk.

Please note that i did not overhaul the transmission, only added new oil into it. if you open dipstick there is foam on it. Please help!!

Regards
