Hello all and thanks for the help in advance. 2000 F350 4x4 7.3L,195K miles, external trans filter, 6.0 cooler, Sun coast TC, shift kit, high volume sump, new fluid and trans filter, I have owned the truck since new. Here is my issue I need help with: When the truck is cold I can drop it in drive and it leaves the line and drives just fine. When I see the trans temp get to about 120 I start to get a first gear slip when leaving a stop sign or light. I just changed the fluid and filter and it has gotten better but still there. Where I really feel it now is when the trans is warm and I shift out of park. I go to drive hit the throttle and nothing for a couple seconds. My driveway is on a slop and if I back up to realign the truck it won’t idle up as it used to do. If I drop into first there is no issue. Just take my foot off the break and it walks right up the hill just like it used to do in drive. From my reading it sounds like I need to pull the valve body and check 3 bolts? Can anyone post a pic of what bolts? If they are tight then what? What else should I possibly check while I’m in there?
