Transmission Problem

My 03 Chevy 2500HD just blew the transmission. I was passing someone and when it shifted there was a loud bang and then nothing. No grinding or anything. I have no gears except park. It is just like neutral in every gear. Broken pump or torque converter ?
  • Got the transmission out today. Feels like the input shaft is broke. I also think something is wrong with the transfer case. There is side to side play in the tail shaft and when I spin the front shaft I hear a clicking sound in the transfer case. Hopefully my buddy can look at it Monday.

    Sorry to hear of all your troubles, but I have good news! With all of the problems you are having, things have to get better!

    Good luck, best wishes for family, including your dog, as they are family to most of us!

    Thank you for your well wishes. My dogs are family. My truck is just a material thing. Everything will work out.

  • I checked the transfer case. No leaks. Transmission is coming out tomorrow. My buddy is a transmission tech and he said it is most likely one of three things. Either the torque converter broke, the pump went or the input shaft broke. He said all three are simple fixes. Well simple for him. I am planning on bringing to him Monday.

    4WD? Have you checked the transfer case for leaks to see if the dreaded "pump rub" reared its ugly head?

  • You're going to have to update your signature now... it stopped purring like a kitten.
  • Could be anything...I know that's not to helpful but get it diagnosed professionally. I will say that I had problems with my 02 2500 that I had owned. It was a bad TC that went out. The problem was that the TC split. Now I later found out that some of the earlier 01-03 had that problem due to the TC being defective. So its a possibility, and as already stated above if u have the 4x4 check the trans case for pump rub for sure....

  • Could be many things. Convertor, flywheel, or if a bang with no other noises, maybe input or intemediate shafts.

    See you have a programmer? If it limits or disables torque management and you were at heavy throttle passing someone, I would guess the input shaft broke.




    Btw I see you are in North Branch. I will be there in the morning for Haydays.
