    Please review my shifter cable routing for g96

    I talked to a gentleman at CMS (where I obtained my transaxle package) and need to measure for custom shifter cables. He said I could go down to a 3"!!! radius of curvature, but I'm aiming for gentler bends.
    So I borrowed one of my wife's garden hoses and ran it back from the shifter, over my cabin heater, just inside the driver's side engine mount, along the main frame as low as possible to avoid header heat, then swooped around the rear of the transaxle (I think I'm high enough to avoid diffuser?), up to the mount on the transaxle. I would add a support for the cables where they swoop around the rear of the transaxle.
    I can just run both cables alongside each other, right?
    Is there a better way?
    Am I forgetting about any obstacles?
    Will the batwing ls1 oil pan interfere with this routing?
    Thanks!

    What you have there is pretty similar to how we normally route them, but I would suggest moving the cables over tighter against the oil pan/transaxle than right under the headers.....and get some insulation wrap for the area near the engine. Also, do not put any zip ties around the cables themselves and cinch them down tight. If the cables do end up getting hot, anywhere you have a tight zip tie, the tie will sink down into the cable sheath and lock up your cable. Yes, you should be able to route both cables together and wrap them up together (saves on the amount of insulation wrap you need).

    The batwing pan does make things a bit tighter, but I would still run them on the top side of the wing of the pan close to the engine rather than close to the header. We've used both the crate LS3 pan as well as the batwing pan....both fit and work.....not sure if the batwing pan has real advantages or not?

    Thanks for confirming Shane!!! Calling CMS now.

    Just talked to CMS, turns out I already paid for them way back when I bought my g96! Saved a few $ there...
    FYI g96 guys, my measurements were 106" for the upper fore/aft cable and 110" for the side-side lower cable. My shifter location is modified - moved forward several inches, the rear cable mount on my shifter is 10.5" forward of this 1.5" square so you can compare.

    That's pretty much where mine are going as well.

    I'd be careful how close you secure the cables to the transmission mount and the shift linkage/levers.

    If there's any torque/play in the mounts, the levers will get pulled slightly and may ruin the internals.

    Thanks for that tip, Tino. I'll make sure to secure everything well. Cables have shipped, should have them this weekend.

    Thanks for the help, shifts like butter! Still need to secure the cables.
