i have a transmission problem and i was told that it was the TCU. i have a 91 accord lx and the part number is 28100px0721. i bought it used from a junk yard and they said that it came out of a car just like mine lx but didnt tell me the year, but idk if it matters. can anyone tell me if this is compatible with my car.

 

Yes it's compatible.the tcu they sold you is from a 92 lx
