2022 Chevy Diesel one ton cab/chassis truck with the 10 speed automatic transmission on December 16, 2022.
End of July of this year at around 46,000 miles the truck would barely pull itself. Torque convertor was going out.
Problem #1 - The Torque Converter Lockup Mechanism
If there is one Achilles’ Heel to this transmission, it is the dismally inferior OEM torque converter. There is a lot of good AND a lot of bad, so we have divided this into multiple sections. The problem here is ironically not design, in fact, it’s a fun-house mirror version of Ford’s 6R140 Torque Converter’s lockup mechanism. Ford’s 6R140 lockup mechanism was excellent in the fact that it locked up facing the stator, rather than the flexplate.
The reality is that the torque capacity of this lockup mechanism, though difficult to test due to variables, seems to die at virtually any power level above factory, OR when tire size is greatly increased without an appropriate regear. Trucks exceeding 500HP or who plan to tow extremely heavy will statistically not survive long. Fortunately, we do offer 2 different Billet Multi-Friction Torque Converters for those in trepidation of this issue.
