Quoted From college man:
If the transmission is under warranty I would suggest taking it back to who did the work. If you wanted to you could
check the transmission fluid to see if the level is correct. You also need to find out if genuine Honda transmission
fluid was used. otherwise that could be part of the driving issues your having.C8-)if you look in your owners manual
for the instructions on checking transmission fluid level. this will guide you on the procedure.
+1 on verfiying if Honda trans. fluid is currently being used, perhaps check with previous owner. Honda’s require ONLY OEM trans. fluid to be used, otherwise problems will occur. As for checking the trans. fluid,first drive the car and reach normal operating temp., then shut-off engine, car in park and on level surface, within 90 seconds check fluid level. You mentioned CEL code related to EGR. What was the code? That would be helpful for troubleshooting your problem.
