I think the plug was mis-manufactured, or the case was tapped too deep at GM. My identical plug only goes about 3/4 of the way in. Anyone else run into the issue Cheng is experiencing?Ends up that while IP-01X is the correct pipe thread, it isn't long enough by 1 or 2 threads.
Guess they don't like when their standard response doesn't work...I sent an email to Gold Plug. They said I should add teflon tape. I then sent the pic I posted here alone with the thread dimensions. No response. I asked again but no response. So much for customer service.
Galvanic corrosion is a big problem for cars because of all the road salt many of us drive through in the winter. My point is that everyone should know that they install the a stainless steel plug into an aluminum case at their on risk.

Both have the 9 speed, all 2nd gen Traverses have 9 speeds.Interesting scenario with the Plugs:
Note: I have TWO 2019 Chevy Traverses.
1. High Country 9 speed Transmission
2. Front Wheel Drive Premier 8 Speed Transmission.
In both scenarios - the original transmission plug was partially out.
I noticed as well the Gold Plus was shorter and less threads.
Considering the original plug did not go in all the way there was little concern from my end.
I ensured I tightened (not too tight) the Gold Plug in more flush to the Transmission.
NOTE: I have astutely monitored any OIL leak (AKA Transmission leak) on my driveway - none so far.
The concern mentioned above could be true: the 'THREADS' could be slightly off potentially and could explain some of the issue.
But I personally did not experience this scenario!
