04 cts transmission fluid never changed now at

Means that you have 24 percent of life left on your transmission fluid.say it's good for 30,000 miles,you would have almost
7500 left till it needs changing.

My 2009 CTS4 should be the same as your 2008 CTS. There is no dipstick tube to check or fill the transmission. The check plug is in the bottom of the pan. It loos like a drain plug, but it is not. The fill plug is on the passenger side of the transmission, just above the front of the oil pan. It is a plastic and rubber plug that is pulled straight up.

You'll probably be better off having it checked and filled at a dealer or trans shop.

Drop the transmission oil pan, replace filter, reinstall pan. Remove inspection cover to view torque converter. Turn flywheel over by hand till drain plug in converter is at bottom. Remove plug and drain. Replace plug and fill trans. with new fluid.

please do not have your transmission flushed , have someone take the oil pan off and replace the filter as well and what ever trans oil you take out replace it as well . no automotive repair shop will warrenty your trans if it should suddenly stop working , but just for your satisfaction ask the transmission repair shop who flushs trans if they guarantee it and have them put it in writing . ive never understood why flush dirty oil and leave the dirty filter in the trans , it collected all dirt and metal wear which is what is causing it to plug up causing it to restrict the oil flow

Most like you need to flush the transmission and I would put one quart of Lucas transmission fluid in too. It will help with changing of gears.

If it has never been changed, I would recommend you get it done now, if you take it to a service shop, nothing has to be removed, the oil changer plugs right into the transmission lines. on the 3rd year, I recommend the ****** filter changed along with fluid.

Yes flush and refill.

replace your radator there is a trans cooler on the side of the rad the leak is internal

Actually, I had a transmission rebuilt by a certified transmission shop and they recommended that I go to a shop to have it flushed and filled every 30,000 mi. and that it was better than draining and filling with a filter change.

tod34 is correct. The "fill" area of this transmission is located on the transmission itself. It is a fluid leveling plug located low on the main case toward the back of the trans. You must pump the fluid in through that hole. If you are on level ground and the transmission is properly warmed, you should fill the transmission until the fluid level is flush with the bottom of the hole (starts spilling out)
