Does anyone have a procedure on how to perform the transmission flush? My car has 49k miles on it, so I need to get it done, but do not want to pay the dealer $299 to do it.

 

This link:

provides a drain and refill proceedure for the NF Sonata. True flushing requires a specialized machine, although I have heard of guys tapping into the side ports of tranny with a modified bucket to perform a psuedo-flush. If you adopt this proceedure, I would perform it more often than 45K.

 

Some examples:

Both plumb into the tranny cooler to faciliate the flushing action.

 

great links, thanks for the info. I definitely feel better about doing the fluid change now.

 

I ended up getting the dealer to do it, cost me $197 out the door. Two other dealers were $195 plus tax.
