Where is the transmission dipstick?
This Site Might Help You. RE: 2006 Mustang GT. How do I change the automatic transmission fluid? Where is the transmission dipstick?
That year mustang does not have one. you have a fill plug and a drain plug. ( why do you need a flush? it is a 2006) here is a step by step for you: 1.With the vehicle in NEUTRAL, position it on a hoist. 2.NOTE: Drain the transmission while the transmission fluid is warm. Remove the drain plug. ?Position a drain pan under the transmission. 3.Apply Threadlock and Sealer and install the drain plug. ?Tighten to 27 Nm (20 ft. lbs.) . 4.NOTE: Prior to removal, clean the area around the fill plug. Remove the fill plug. 5.NOTE: Do not overfill the transmission. This will cause transmission fluid to be forced out of the case. Fill the transmission with the recommended fluid. ?Make sure the fluid is 12.7 mm (0.5 inch) below the filler opening for the correct fluid level. Using a tie strap, measure an inch from the end and bend it at a 90-degree angle, place it in the filler opening and check the fluid. Adjust the fluid level as necessary. 6.Apply Threadlock and Sealer and install the fill plug. ?Tighten to 25 Nm (18 ft. lbs.) . the fill plug is on the drivers side of the transmission and the drain plug is on the bottom. Good luck!
It is a little more complicated that an oil change, but find a service shop the can drain it all buy pumping it out, they get it all, If you do it you can not drain the torque converter it still hold a quart of old trans fluid. Get a deep sump pan installed, change the fluid then and you sill have a drain valve/screw then and you can do it yourself.
