Actually, from what I’ve learned, a torque converter shudder in 8-speed (8L45 and others) transmissions used in trucks, caddies, and Corvettes (to name a few).
If you have addressed this before, I apologize.
The story from the dealer is the corrective ATF fluid is unavailable for a month(s), first of the year 2023. If familiar with this issue, what damage might happen waiting that long to get the correct fluid? My recently purchased Colorado has 24000 miles and has been shuddering between 40-50 mph and above 60 mph, so a lot. Any info on this issue at all would be appreciated. Like a complete cure IDEA if the replacement fluid has no effect.
