Not my first rodeo.... Had a 3FE did this job many times... Pull the drain plug T .Case and no oil comes out.... Pull the fill plug ... It has an Allen wrench plug and a spring behind it.... No fluid drains.... Where is the fill plug???????.. Just bought this thing and drove it 420 miles home.... Drove it like I stole it at that. What am I missing... Thanks..... Now to change the rear diff.... Thanks in advance...
