My 2001 windstar kicks or harsh shift (it throws my neck back and to the front when I'm in a stop and hit the gas or when driving and want to go faster I can fill the van quick jump back and front the motor sounds really good I changed the trans oil and filter but still the same. Before this started I put some break oil in the canister some oil spilled. I took the air filter out to check if that had anything to do with it and notice oil in the first electrical connection that goes into the transmission not the one that have to do with the shifting but the one next to it cleaned it but still the same any help will be more then appreciated thanks

That means excessive slip is detected. Have a trans guy look at it.

All this problem started when I put brake oil in the van and spilled some so the 2nd day after trying to find out what was the problem I checked to see if the brake oil had anything to do with it I found oil inside the connection next to the transmission range sensor I cleaned it with electrical cleaner and connected it back but it didn't help, Changed oil and filter in the transmission and motor plus spark plugs added lucas to the transmission, Tranx x, Transmission stop leak since it started leaking I been trying all this since I don't have money to take it for repair.

Today I decided to disconnect the cable that had oil inside and test drive the van sorry don't know the name is the one next to the Transmission Range sensor and when I turned the van on the first thing I notice that the o/d off light was flashing but the minivan was driving with no problem drove it 30 miles up hill was more harder before but it went up like nothing and is driving with power shifting OK can you please advice thank you

When you disconnected the plug it took away the torque converter clutch that is slipping causing your code 1744. It's a bad torque converter at least that is my opinion but have atrans guy look at it.
