    Default 4l60e 4th gear shudder

    Just had leaking radiator repaired at local shop. replaced radiator and drove truck and noticed a brief shudder in 4th gear that is intermitten. when shift into 3rd gear manually the truck does not shudder.
    put back into 4th gear/overdrive will get intermitten shudder for 1-2 seconds at steady speed. IF I take my foot off gas when shudder starts it stops or if i manually put it in 3rd it does not occur. I can start out with gearshift in 3rd and transmission shifts fine with no shudder. Any help greatly appreciated.

    Usually when changing a radiator you will lose a couple quarts of ATF. Did you check the level? If so when the shudder occurs try stepping on the brake lightly and see if the shudder stops. If so you may have a misfire. Next step is to have it scanned for trouble codes.
