I have a BD transmission in my 98 and the problem is it doesnt engage lock up when im at Wide Open Throttle! easy off the trottle and it will engage.

i have a manual TC lock up switch, and its the same problem. say when i wanna make a locked shifts run, it wont engage lock up (not even if i activate the switch) unless i flip the switch during while stopped, then mash the pedla, and as soon as the truck shifts to 2nd it has lockup all through the gears.

also i sometimes get a shudder when locking up (at light throttle)
