> [@m.litchfield](#): > > like Del B. also have a clunking noise every 4,5,or 6th start ups. Del B? Are you referring to a recent _Best of Car Talk_ podcast? Suggest to provide some more info: engine/transmission configuration and explain w/more detail - What part of the car does this sound seem to be coming from? - When? Under what conditions? Driving down the road? During engine cranking? Shifting from P to D? P to R? etc … ---

Del B. left a poor description of the problem. “Startup” could mean starting the engine or could mean pulling away from a stop. With only 1500 miles on the vehicle, this sounds like Del doesn’t like the way his new truck shifts. ![image](https://global.discourse-cdn.com/cartalk/original/3X/7/a/7a97489a2a3dcd60b927e25f20eded1b1de3b07a.jpeg) ---

Do you have the 6 speed or 8 speed automatic??? And how many miles are on it??? The 8L45 (8 speed) (and 8L90) transmission had a rough beginning. You may need to find a good late model transmission builder that knows how to repair, not just rebuild them… I think they might have had some TCM issues as well… [https://gmauthority.com/blog/2023/03/gm-8-speed-automatic-transmission-lawsuit-granted-class-action-status/#:~:text=The%20suit%20was%20originally%20filed,1st%2C%202019%20are%20defective](https://gmauthority.com/blog/2023/03/gm-8-speed-automatic-transmission-lawsuit-granted-class-action-status/#:~:text=The%20suit%20was%20originally%20filed,1st%2C%202019%20are%20defective). ---

We have a lot of Canyons in our fleet in that model year range and some of them have those same symptoms 😆 ---
