  1. Hello all

    We have a TEREX TA30 truck with serial number of A7751209 model of 1999.

    We have a problem of shock shift at 2nd to 3rd gear. We try to calibrated by AEB many time with different condition, but the same problem.( AEB give OK message).


    We changed the TCM with another truck TCM and still the same problem.
    We check the valve body and clean it. Change the load sense . Adjust all the speed sensors.


    Any tips you promote so I can start with it??
    I noticed one thing, no shock shift when you move up hill. And increase when you ride on down hill.


    Thanks .
