I’m confused. Doesn’t the 5BW only have a eLSD? So there is only one thing to worry about back there with the specific Delco 10-4131 fluid. There isn’t anything else differential related to worry about correct? I assume all the other differential capacities mentioned in the manual pages are...

Oh, so the 3.2mm below is for the transmission and not the ediff? So is the proper ediff level to be filled up to the plug?

My new 2026 5BW I noticed the coolant level cold was about a cm or 2 below the fill line. The manual doesn’t really say to check it hot or cold. When hot its about half way higher but still not to the line. Anyone else have coolant that wasn’t filled all the way from the factory? Hopefully I...

Where is this specified and how is anyone supposed to get it to that level? It sounds like others are overfilling it by filling it till it weeps out the top hole. And how do you get an accurate fill level if you back up a 5BW onto ramps to do this procedure?

My 2026 is also missing the screws. I was able to put 2 screws in that go into the black plastic piece. But the other 2 holes in the fabric liner didn’t seem to align to any screw points at least as much as I could barely move it. Anyone know if these 2 holes do line up with something?

Does anyone know what #18 does? How important is it to have on the car? Like if it protects the brakes from strikes or if it’s just better aero for mpg. The manual does say to remove it for track use if you have iron brakes but mentions nothing about what to do if you have CCB. I got a set...

Anyone used this angled oil filler with the 5BW and with another gm thread funnel successfully to be able to poor oil quickly without risk of it leaking out over the engine? Does it fit right on this car? Site Maintenance Any other recommended funnel to achieve leak free quick filling? The...

Is there an official 5BW street alignment spec for street use? Sounds like you do need to swap the toe links back and forth if you only track occasionally and mostly do a lot of normal driving and want to preserve the life of the tires. Where are you all getting alignments done? How good a...

What is the full street spec alignment supposed to be and where can you find this info?

Is it a lot of work to swap v8v toe links on before a track event and swap them back off afterward? Or is it a very simple thing to do that as part of the alignment any shop can just do it for you?

Cool, so it does work with a manual. How many button presses can you make the code? And if you stall the car, do you have to re-enter the code or it’s only if the car was turned off first? Sounds like it would be stressful if you stalled it and needed to get it restarted in the middle of an...

How does the IGLA work with a manual 5BW? The videos I’ve seen for IGLA show the engine starting but just prevent switching into gear with an auto. Not sure how it behaves with a manual transmission.
