"Reduced performance reduce clutch use"
Good morning all.
Looking for help/advice on a reoccurring warning now MIL illumination after minor modifications. Vehicle- 2019 camaro LT 2.0t Transmission- standard 6 speed Mileage- 49k Back story- I purchased this this used at the dealership in June with 32k on it. The car handled well and drove fine. All the gears shifted as they should with no slippage. 3 weeks ago I decided to swap out the factory exhaust for the Flowmaster 817751 American Thunder Axle-Back system. The car sounded great for a 4 banger. Immediately after the install, (second drive cycle), I got the illumination on the dash "reduced performance reduce clutch use". I really didn't think much of it. I figured it's probably because of the differing back pressure of the exhaust. (The torque and hp gains are minimal for the swap). It didn't happen often, only in 5th and 6th gear under WOT. Last week I installed the Injen CAI and ZZ performance high flow catted downpipe. Immediately after that I noticed the warning would pop up more. Now in all gears from 2nd onward. Last night's illumination was followed by "service transmission". I plugged in the Foxwell and got the code (P17A2) after some research. I found a service bulletin on the Camaro/ATS BulletinNo.:20-NA-153 Date:August,2020. It states "Some customers may comment that the MIL is illuminated. Some technicians may find DTC P17A2 (Transmission Clutch Slip Detected) set in the Engine Control Module(ECM). In some instances, the output speed sensor reluctor wheel may be slipping on the shaft due to low output shaft nut torque." Your thoughts on this issue? Can it be the modifications? Or have you had this happen to you, what was the fix? Thank you all for reading and responding in advance. Uploaded the TSB for reference. |

Thanks for sharing the code that triggers the clutch slipping and causing reduced engine power (really scary and dangerous when the power just cuts out all of a sudden IMO). I've always wanted to permanently shut that "safety feature" off for good. Thanks car, but I'll figure out on my own when the cutch is going bad the old fashion way.
