Let's say I want to make sure the truck is shifting into all gears and my torque converter is successfully locking, should I feel it shift 4 or 5 times? I hear people say that the TC should feel like a shift when it locks. I will try to do a video from 0-60 so everyone here can see if it is properly shifting through all gears. I notice that if I let off the throttle when I get close to the top end of a gear, the transmission will shift up. I think that is normal operation.

What about the brakes dragging? They drag just enough that sometimes the truck won't move at idle or it will move slowly.

 

Here are pictures of my ring gear when I opened the cover to do the fluid service not long ago. I don't see any markings on it in these pictures. I don't know why anyone would change from the stock 3.55s seeing that I don't even have a gooseneck hitch on the truck.
