1998 honda civic LX sedan, 90k on the motor and trans.

bought from a body shop, and fixed. front end wreck. throws NO TRANNY CODES.

now i'm, driving it today and the IACV went bad. i was sitting in the drive thru, and i let it run for about 5 mins revving up and down before I had a chance to move forward. when i went to go forward, it seemed as if the tranny wasnt in gear, but it was in drive.

put it in park, then put it in drive. it revved, changed gears, then moved. it did this twice in a row while i was waiting to move forward.

got it out of the drive thru, no probs.

I already drained and filled the fluid.


any thoughts? i'm thinking the IACV keeps the trans from shifting while its revving, th protect the trans/motor, and replacing the IACV would make it work.
