I be going down the road then the rpms go up and the truck s starts slowing down accompanied by transmission fluid coming from the vent hole on the dust cover under the bell housing covering the torque converter.
Recently it's been having a hard time shifting out of 1st.
I did the annual fluid and filter change this past March,for the first time the fluid is burnt smelling and is gray-ish dark red.
Fluid temps go as high as 180 degrees sitting in traffic and drops 15-20 degrees at highway speeds.
My friends know how much I over maintain our truck but for a truck hauling it's own weight of over 8,000 lbs everyday finally taxed the TQ and transmission
We won't get into Brian's till mid/late August.
