Re: Trans Fluid for a twin ultramatic? Power Steering fill mark and fluid?

I believe that groan and chatter may be two distinctly different problems. I've experienced chatter with high-mileage and well-worn Ultramatics, but never with Twins or GearStarts.

I suspect groan is a direct drive clutch symptom and chatter is a high range clutch symptom. Just guessing, no real evidence.
