Downshifting/ Irratic throttle- help!
 

i have a 2003 2500 cr with the 48re trans, a few months ago the truck started unlocking and downshifting on the freeway and had irratic throttle, and i couldnt get over 30mph. the next day when it would rev high, the transmission was making noise so i had the transmission rebuilt he atated new od sol, governor and transducer, it drove fine for a week then the same issue but without the noise, its an intermittent problem. it will be fine and drive normal for a bit then be back to the same issues, i since then have replaced alternator, battery terminals and installed a bd noise isolator. im getting sick of spending money and the next step was going to be an apps sensor. Some help would be greatly appreciated.

I would check the apps/tps sensor.
