Hey guy have a question. i just picked up an 07 sedona. there is a whine in the car that seems to be coming from the tranny. doing a little research showed the filter is internal and cannot be changed. i have done one drain and fill so far which seems to have quieted it down slightly. a few people on the kia forum seem to think the filter is clogged and starving the pump. i was thinking about using seafoam transtune hopefully dissolving any contaminates, and doing several drain and fills. Any recommendations on things to try. the van has 124k on it. and the fluid was somewhat dark
thanks
thanks
