4F50N Transmission Problem (Extreme Detail)
Ok, so get ready for this one. I am new here (hi everybody). Ok, so here is the story. I bought this 2000 Taurus SE off of a friend for $300, 110k, engine working, but the transmission had been acting weird. You put it in overdrive, and it goes to about 25 or so and then starts bouncing off the powerband. Like as in, you could clearly tell that nothing was engaging. Now when I was test driving the car, if I was to just simply press the gas harder, the car would then move faster. I got the car up to 65 once when testing it (I know, bad idea), so I don't know if there are any internal problems. The only way I got it to go that fast was if I was in low gear by the way. Weird, huh? Alright, so then I came home and completely started taking stuff apart. I had to find a way to pull the valve body cover without dropping anything that I didn't need to. Needless to say I found a way. I unbolted the tranny mount and took it off the car along with the big piece of metal that connects it from the tranny to the body. So I pulled the pan off, and then the next day I took off the valve body. I took some pictures of the pump shaft, and nothing on it looks sheared. I then looked into the hole towards the TC and I didn't see anything out of the ordinary. I then started cranking over the engine with a ratchet to see if the shaft was turning, and it was, so yeah. Now here I am on this forum for the first time, asking what might be wrong. I tried to do research before, so I could get straightforward support. What could possibly be wrong here. Something in the valve body? A sensor? I'm really new to this new transmission technology. I will attach photos here too. I have NOT checked the solenoids YET, that's tomorrow. I turned the pump with the shaft in by hand and it turned fine. I did NOT however, check the pump when It was all together. Oh yeah, The fluid smelt burnt a little bit, not a horrible smell, just a bit of burnt smell.
