Anyone Experience This Problem
I have a 95" F150 supercab with a 302 and auto trans. Its is freshly tuned and up to snuff maint wise.
My problem is while driving down the highway and cruise on and going up a slow upgrade the rpms will drop 100 and then I notice the timing drop down to 6 deg. Then the TC will unlock and rpms go up 400 and the timing stays the same or drop to 4 deg. It still cant keep speed so the trans drops to 3rd and rpms go to 3000 and timing stays at 6 to 8 deg. It has no torque to climb the hill due to no timing. When the motor is at 3000 in third it is just reving and no torque. It is not the trans slipping (new rebuilt and new TC 3000 miles ago).
Anyone have this problem or know how to get around this issue? I know my mpg would climb too due to this lack of torque. I am steady at 13.5 mpg now on the highway.
