    I am having a little problem, when I lock in to 4-Low its starts to move then slips like crazy then it will catch all of a sudden.
    It does not do this is 4-Hi. Do i just need to rebuild it ?

    It's in a 94 Chevy Suburban K1500 with a 4inch Rancho lift. 305/70/16 ProComp A/T, 4.56 gearswith a aurburn limited slip The tranny is a 4l60-e, TC is a NP241.

    I had a friend that had the same problem and it was a snap ring or lock ring on the main(output) shaft that had broken or come off.Not sure exactly which one it was cause i didnt get to see it but its an internal problem for sure.......Also check to see if your shifter is out of adjustment!
