2005 Dodge Magnum Question: Transmission flush v. drain and and fill

Either cooling system flush or trans flush changes all the fluid and not just what happens to drain out plus is done under pressure with cooling flush machine or the trans pump. Recommend trans filter change at same time or clean screen if that is what it has. Optimum is the flush but could be overkill depending on mileage. Your tune estimate can be generated at the estimator link at repairpal home page. The estimates for the trans and cooling system work will depend on the shops in your town. There is no all encompassing price for this work. Can depend on shops and type of trans fluid used and type of coolant used.

Simply draining and refilling transmission fluid will yield little benefit to the healthy life of a transmission, as only a portion of the old, dirty fluid is changed out. None of the fluid in the torque converter will leave the transmission. Over time, contaminants LINE the interior of the converter. This displaces fluid and compromises the proper operation of the transmission. A FLUID FLUSH, using a cleaning chemical (my recommendation would be the BG product) needs to be performed to remove and replace ALL old fluid. Be VERY careful to replace the fluid with the CORRECT fluid for your car. If a shop offers an additive that will 'make the fluid that they have in-stock act just like the special fluid needed' - walk away!
