Went to pass someone later that week at 55 mph, pulled out, floored it, nothing, let off tranny caught up with its self. Been doing it ever since. All gears are there, no lights blinking, new tranny fluid/filter
2 different vss but made it worse til I put the original back on, new mlps too. No help, any ideas at all?

 

Motorcraft only for the VSS, is the general concensus.
Wonder if maybe your torque convertor is starting to go ? If all else fails you might try a new one of those - if it works, it will be much cheaper than a rebuild. Only a couple of hundred if you can install it yourself.
Try to track down any other possibilities first of course.

 

i hope not, truck has 193k on it, it shifts ok as long as I don't give more than 1/2 throttle at once, I was debating on new tps but wasn't sure

 

You can test the TPS before throwing money at it.

 

ok, the truck shifts good as long as I don't give it more than about 1/2 throttle, didn't hear any odd noises or feel anything vibrating, not sure if it helps or not but speedo cable has been bouncing going faster than 45 since I got it (before the downshift issue started) never heard any pop, grind, anything until it clunked the first time I put in R o/d light only comes on if I push it. I got a used cruise module (left inner fender by hood hinge) it burnt up and I salvaged a harness and used module but all it did was fix the horn.
