1997 Ford F150 3speed auto w/od 4.6 motor

Transmission began leaking fluid so I took it out & replaced the front seal. Put back together & drove it & it was still leaking. Pulled it back out & replaced pump O-ring seal. Put back together & still leaking. Torque converter appears to not be leaking.

Any and all input will be greatly appreciated. Please ask if you need more info.

PLEASE HELP!!!! THIS IS THE ONLY VEHICLE WE HAVE.

 

So you replaced the seal that goes around the T.C. shaft, the seal that goes around the pump housing, I am looking for a diagram on line, what transmission is it?
