Hi All,
May have been discussed -
Short story - many GM transmissions are apparently afflicted by a shudder with wavering RPM, clunking, etc - 2016-2018 so far. GM reportedly changed the fluid requirement a year ago, then when that didn't solve the problem, they started replacing torque converters. But, they started getting returns on the torque converters.
In late 2018 they started shipping a new transmission fluid that would reportedly fix the issue ... just had mine replaced on a 2017 Silverado that was exhibiting the issues. Initially, seems to have fixed issues on mine.
Part number is: 19417577
Anyone have engineering or insider insight on the fluid, sourcing (assuming it is Mobil syn of some sort)?
Thanks.
