Hello everyone!

So I looked at the transmission linkage and everything seemed okay, I checked the transmission fluid again and realized that it had barely any transmission fluid at all, so I went out and bought some fluid and filled it up. Presto! the car stopped slipping! It now goes in both reverse and drive.

Now for the new problem...I took it down the street and gave her all she had, all 10 MPH... So now I'm left stumped trying to figure out why the car won't go beyond 10 miles and hour. Any suggestions?
