How’s it going everyone! Landan with LMR.com. In this installment of LMR Basics, I’m going to show you my general procedure on changing the transmission fluid. I’ll be doing the work on this ’92 coupe which is equipped with a T5 transmission and will be getting filled back up with Royal Purple Synchromax.

A few items to have on hand before you begin is some quality brake clean, shop towels, rags, drain pan, jack and jack stands, a three eighths ratchet with a small extension, and to make life easy; a fluid transfer pump. You can pick one of these up from your local auto parts store.

Begin by jacking the car up and supporting it via the jack stands. Make sure the car is cool and not hot. Locate the drain plug on the transmission. Position your drain pan underneath the transmission and then loosen and remove the plug with the three eighths ratchet and small extension. Allow the transmission fluid to drain.

Inspect the drain plugs and spray them down with brake clean. Once the fluid has slowed to a drop, thread the drain plug by hand and then tighten it down. Be sure not to overtighten. Locate the fill plug and remove it. Use the fluid transfer pump or run a clear tube with a quarter inch inner diameter from the engine bay into the fill plug. Slide the tube over the bottle of fluid and begin filling the transmission.

Double check your owner’s manual for the correct transmission fluid capacity. Fill until fluid starts to seep from the fill plug. Remove the tube or transfer pump and tighten the fill plug. Perform a quick visual inspection and that completes a successful transmission fluid change. Be sure to properly dispose the old fluid per your local regulations.

Depending on the transmission in your Mustang, a job like this normally takes about forty-five minutes to an hour. I would spend a little extra cash and invest in the transfer pump. It does make life very easy when doing jobs like this. Other than that guys, this was my general walk through on a transmission fluid change.
