Ok guy's I'm new to this board (see post count) I have a 90 prelude 2.0s, auto tranny. I hade to change the tranny and now I get a CEL after a few minutes of driving, usually at the same time my s3 light starts to flash while i'm in drive (drive light, CEL and flashing s3 on at same time). Any idea's? How do I check what code (where do i put the paper clip)

The final problem I have is it takes a while to shift from 2nd to drive when it is cold (like up to 10 minutes of driving) and yes I checked the fluid and it is full. SO where do I go from here. Thanks Guys......

Oh ya nice BB buy the way....

 

Anyone?

check the second post in that thread to see how to check the code yourself. You can also take it in to a place like autozone and they will check it for you (i mention autozone becuase i just read they check it for free?). Not sure about your second question. Welcome to HT
