Thread: Acceptable Torque Slip (TQ-S) Readings / Rates

    Acceptable Torque Slip (TQ-S) Readings / Rates

    I have been trying to find information out regarding what are considered acceptable torque slip rates (Maximum / Safe) on a 68RFE throughout the gears before TCC lockup occurs.

    I have not been successful in finding much.

    My truck is stock other than a 60hp duration box tune, 23*, 1850 pressure, mild torque setting on RaceME Ultra.

    My Ultra is always running TQ-S PID.

    Can someone please let me know what the max torque slip reading should that would be considered acceptable.

    I understand that once lockup occurs the rating will be significantly diminished or non existent.

    What I would like to know is how much is too much during 1st, 2nd, 3rd and some of 4th.

    Thanks.

    I see it all over the place.

    I have seen it in the 900 rpm range occasionally.

    It is usually 200 - 700 before lockup, higher ranges in the higher gears. Not sure if this is normal because I am running 38" tires with 3.42 gears.
