No DS sport mode, what should I try next?

[08135IFL]

So my 08 w/94k miles no longer would engage DS when moving the shifter left. Common issue, it's the purple and white wire breaking, etc...

I tear the console apart, isolate the wire loom, remove the black tape and 4/6 wires were broken. Viola! Found it. So I followed the instructions found online and spliced and heat shrink wrapped all connections.

But... I start the car after all wires are reconnected and still no DS mode.

I read people saying it could be a fuse, but what fuse?

Can anyone help troubleshoot anything at this point?

Paddle shifters work up and down but switches back into D mode as is designed to.

Shifter itself will manually shift up and down as well but switches back to D mode as designed to.

It's like it simply won't engage DS mode but all shifters, etc... work fine.

Thanks in advance for any help.

Problem solved.

The connections for the shift boot trim piece (one blue, one white on the underside) apparently must be plugged in for DS to engage.

Literally a $3 fix (for a 10 pack of pack heat shrink wrap sleeves, only used 2 out of 10 in the pack) and a few hours to tear apart the console and put back together.

$1,000+ at the dealer. Insane.

Simply incredible.
