Default Transmission Flush

My transmission fluid is getting dark--is this a problem waiting to happen or would a transmission flush be the answer?

Kia does not recommend flushing. Drain and fill. If you Y/M has a filter then I would change it also. Not all Kia's have a replaceable filter. You didn't say how many miles you have on it but drain and fill within 5000 miles might not be a bad idea.

I read it somewhere on a Kia web site. I am not sure if it was on here Kia Global Information System (KGIS) or not. I just figure if they don't recommend it and you do it you will have to fight it out with them over warranty work.

I have about 97500 miles and interestingly--Kia recommended somekind of transmission service for 179.00 when I got my oil changed

I can't answer for Kia as to what they are doing for their service and why it's $179. I do my own and it cost about $8.00 for a gallon of Dexron III to drain and fill. Ask them is all I can say. There is a difference between using a machine to replace the fluid and when they reverse(flush) the fluid.

Default Hey

Your better off with a drain and fill not a flush and also try a a additive to clean whatever else is dirty in there but not a cheap pep boys additive spend the money and do it right the first time.
