Guys, I’ve been hearing what I thought was an exhaust leak on the driver side of my truck. Turns out the manifold to converter bolts were loose. I was able to get a little bit of a turn but not a whole lot. I snug them up for now but I was hoping to find the torque specs for them and also understand the seal type. If it is a metal seal I feel better about retorquing and moving on. If it is not a metal seal I will likely replace it. I am hoping it is just a relaxed seal after some heat cycles and miles on the truck. Not trying to go to the dealership for a $10 part under warranty.
I have been getting annoyed with my auto light setting. If I go through a shady spot the interior lights dim and outside lights come on. The biggest pain is the inside lights. It is sunny, so I have my sunglasses on and can barely see. I end up having to constantly adjust the level with the dial. Every other vehicle I have you can adjust the auto sensitivity, but I am struggling to find it in the truck. Is it adjustable?
I have not had much luck confirming the location of the 8 speed TCM for the 2018 Sierra. Does anyone have any descriptions or pictures? I have seen a few older threads stating it may be in the transmission, hoping wherever it is access ins't a pain. Thanks.
Does anyone have any recommendations/links for lower door sill protection? Not sure of the proper name. As my daughter gets in and out of the back with her little legs, sometimes she catches the painted part without protection. I was thinking maybe a 3M film or something, but I have not see anything cut for it. Thanks.
Removal was easy. First remove the pedal assembly. There are two plugs, twist lock plug and push in wire retainer. Loosen the 2 torx screws that hold it to the bracket. Once that is out, (3) 10 mm nuts hold the bracket with the adjuster. There are 2 plug in connectors, wire retainer clip and twist lock plug up top. Not sure what the top twist lock piece is, so be careful with it lol There are actually (3) washer you need to space out the motor at the (3) screws. If anyone knows what is connected up top on the positioner bracket let me know. I am curious.
Thanks for the post. I strarted to research some tuning info and came across this. The lag is miserable. My TSX I could just stick it to the floor, but the truck has a LITTLE more power Anyway, I don’t want to crack in to the tune quite yet and figured I would check this out. I feel a lot of times I press the pedal and nothing happens (exactly what this thread was showing as an issue). I have adjustable pedals and the lower bracket didn’t move much. I was still able to put an 1/8” rubber washer under the bottom right corner like the paint stick. Mine looked like it was rocking right, not necessarily having a gap to the firewall. What I saw on mine was when the pedals were all the way to the floor (where I keep them) the stops were not bottomed out. I ended up puting some washers (0.040” thick) between the motor and the plastic frame. See the picture where I am pointing. That took the slack out of the adjuster and nearly bottomed out the guides. I tried a rubber pad under it, but I guess the motor stops at high current draw and did not bottom out. There is still play at the top, but nothing like it was. I need to find a way to load the videos, half my accounts are inactive and closed lol
