In 3rd or 4th gear under a load like when going up a decent hill, I can feel some shuddering or slipping of the torque converter. Is there something that can be adjusted to try to tune out the shudder or slipping or whatever might be going on?

I see the ramp in D2216 and some TCC slip tables that I feel might be able to help some of this, but I'm not sure where I should start..

Thanks
