Twin Ultramatic Problem

Posted by Rocky46 On 2012/9/8 4:56:55

I wonder if any of you wizards out there can give me a hint or two as to the most probable cause(s)to what`s happening in the transmission:
The selector is in H or D, and as long as there is a load on the trans everything works fine. When the load is very little and I press the gas pedal just a bit down the direct drive clutch? slips? with a little rumble, and I have to press the gas pedal further down to get some load avoiding the slip.
Otherwise everything seems to be ok, except a minor fluid leak from what I can see occurring from the bell housing after driving minimum 20 miles.

Thanks
Tom
