I wrote to you before you said the transmission fluid is pink. If it's pink then you have a mixure of radiator fluid (water) and transmission fluid. You said that the truck won't go up a ramp then you need to do a stall check. This will tell you if the torque converter is functioning correctly. If the stall test is good then you need to bleed the inchig line that goes to the top of the valve assy. If that does't work call me. Look at my profile and get my number.
