Modulator Valve
1990 f150 5.0 2wd
This problem has gotten worse and now is time to fix it. I started to notice I was losing a little in throttle responce especially when trying to pass another vehicle and it has gotten to where im driving around 40-45mph and try to accellerate the rpms will rise but the truck wont move. Im thinking this could be a modulator valve due to past experience but where is it located on this truck and do you think this could be it.
Trans was rebuilt 1yr 1month ago and trans fluid and filter will be changed soon.

This is assuming you have an AOD trans.
