The problem started about 6 months ago starting of winter and the temps outside right now here are in the 50s and lowes are in the lowe 30s it seemed to be softer when it was colder or it just goten worser I dont no if its the tranny or something els I did have a noise that souned like a yoke during the sumer berfor winter but its gone away. O and before I had the tranny flushed I tried lucus transmission fix and trans x additives no good and I disconnected my battery pulled out the main car computer for an hour and pulled all the fuses out no good thair ether I let my truck warm up for 3 min problem still thair.
