Thread: TCC Slippage.

  1. #1

    Default TCC Slippage.

    The converter is a 3800 9.5'' converter. At cruise it takes a few seconds to finally lock and then it will slowly start slipping.. D2903 and D2904 are raised accordingy.I logged Converter Clutch Slip Speed. I raised D2905 25%-30% and got the converter within 20-90 rpm slippage, then after a few miles down the road it got to over a 150 rpm and slowly kept on going up to 250 rpm until we came back. How much can a guy raise this to? Also today the its gettin a shutter at higher rpm, is there a posibility that the clutch could be bad?
