Good topic. Mine is also showing signs of wear such as jumping out of 3rd under torque. It still runs very quiet though - if that means anything. I am running a 235, but I baby it.
My brother had a 1950 1/2 ton that occasionally jumped out of 3rd and attached a bike inner tube to the floor under the shift lever and would simply reach down and slip the other end over the lever whilst in 3rd.
Worked that way for a long time. He called it a "Tennessee overdrive". I guess I have 200K miles on this one. I looked at the Chevy Assy Manual for a part number and found #3845068 for a LH 3100, but not sure that is correct for mine. Does anyone have a good part number I should look for?
