ECM question
hey guys, i purchased a used ECM for my vehicle and had been driving for over a month with no problems. One day i noticed my car was shifting weird and 1st gear would take awhile to shift, the RPM's would also bounce around. i ended up getting a check engine light with the OD light flashing
got these codes: P0500 (speed sensor) AND P0720 (output speed sensor circuit)
before i change the sensors i had a few questions. When i purchased the used ECM i had to search for about 2 months before i found one that i thought was matching numbers

If you look at the ECM, the black part of the label below the toyota sign, it reads 89661-33340, both the used ECM and my old non-working ECM had identical numbers, now the other numbers below that read 175000-5804 dont match, the only part that is the same is the 175000 the other 4 numbers are different. I thought only the main numbers that are in the black label mattered, was i wrong ? can the ECM be causing the shifting problems ?
Any help is appreciated
