Cadillac CTS transmission shudder and slipping gears issue with widespread 8L45 variant concerns on Cadillac CTS

Some Cadillac CTS owners report experiencing transmission issues, particularly with the 8L45 variant, including transmission slipping that can lead to a loss of acceleration or difficulty in shifting gears, often caused by worn-out clutch plates or low fluid levels. Additionally, some owners have reported delayed engagement in the transmission, which can render the vehicle inoperable if not addressed promptly. The 2017 Cadillac CTS is also noted for transmission problems such as slipping gears and unusual noises like grinding or whining. Concerns related to the torque converter have been highlighted, with Technical Service Bulletin 18-NA-355 addressing shudder conditions in these transmissions. Internal transmission issues, including shuddering and hesitation, may stem from hydraulic malfunctions and the circulation of metal shavings. Furthermore, low-quality silicon has been identified as a potential root cause of these problems, with recommendations for a flush to mitigate slippage. Regular maintenance and prompt diagnosis of any unusual symptoms are crucial for preventing these issues from escalating into more severe problems.
