We got to College Station, TX from Knoxville, TN and a rattly noise from the torque convertor area started.
We got towed to AAMCO and they are going to pull the Trans and see what is making the noise.
Noise when idling in Park, the diminishes in drive. It still goes forward and back just fine. My guess is the flexplate or torque convertor bolts or something inside the torque convertor.
They tore apart the transmission and found that the snap ring that holds the bearing and shaft of the drive sprocket of the big chain in the back had broken and allowed parts to start moving around and hitting things and making the noises.
Any ideas what might cause this snap ring to fail??
Thanks to JimK and JimB for responding to my calls.
Thanks to Manny for advising the guys at AAMCO how to properly rebuild the trans for the GMC.
They got the trans rebuilt and it purrs. Shifts smoother than ever and I had no complaints before.
Have credit card, will travel!!
