Transmission fluid partially changed using Siphon Hand Pump Ford Econoline e250 - Project Van

The transmission does not have a drain plug so I used a hand pump to remove some of the transmission fluid and replace it with new MERCON-V Automatic Transmission fluid. The red hose was not long enough to reach the fluid so i had to go buy another hose that was longer to get it to work.
