Or take the right size hex key, cut it to an inch or inch and a half long. Insert it into the correct size socket and viola! A usable "socket/hex key/transmission drain plug" wrench. It's a lot cheaper. :angel:
When I had to change my trans fluid, I had a trusted trans mechanic do it. He's done work for me before....total rebuild of another Ford tranny. He flushed out the fluid on my '05 and changed the fluid in my transfer case for the price of what it would have cost me to buy the fluid alone.
