    I was chasing down a heat shield rattle and I noticed this broken wire housing. There is no wire in it and it just kind of flakes away. I can't figure out what it would be for. I'm sure someone here knows. No CEL or issues. Just happened to notice it. 20220910_182223.jpg

    Its the grounding wire for the transmission, pretty easy to replace.

    Good deal, thanks guys. I figured it was some sort of ground wire but I wasn't sure what the point was as I'm not suffering any adverse effects. I did order the new strap above so I'll throw it back on since it's an easy quick fix.

    Custom bug spat pattern hood, grill & bumper. Dead Live Oak leaf collection under hood, cowl and lower fenders. Beach sand custom floor covering.
    A note on how important ground straps can be. The original Dodge Omni and Plymouth Horizon models had a problem with premature front wheel bearing failures. The cause was found to be a ground strap that was bolted to the engine but had a toothed push on connection at the painted unibody. The connection wasn't electrically sound so some current passed through the engine, drivetrain and wheel bearing to the front suspension and to chassis ground. The arcing in the bearings caused them to fail. I worked for a Chrysler Dodge Plymouth dealer when the service bulletin came out. Fix was to scrape the paint away on the unibody under the ground clip.

    A Facebook group member said he was having issues with bad shifts which is what prompted him to replace his and it fixed his issue.

    I will be for sure. I already ordered the part. I have no idea how long it's been broken. Probably quite a while.

    I welded 3 transmission shift cables before I realized the ground wire wasn't reinstalled after removing the engine. Not on a Tundra but none the less they are important!!

    I ended up buying one at the local part store and put it on yesterday. Took 5 minutes and luckily I was able to get the nuts off without snapping anything. Crazy, the thing had basically disintegrated.

    Should be good for another several years now.

    I have the same issue with that ground wire rusted on my Sequoia for a long time. However, I never really noticed any issues with transmission or transfer case going into/out of 4WD. I replaced it with the 15" ground wire from Dorman on Amazon just in case. 15" is way too long but it'll do.

    Thanks for the tip! Just rolled under mine and it's toast, hopefully this fixes the funky downshift I've noticed lately.

    Rust. That strap is exposed to the element. Water, salt, sand, mud.. etc.. it will eventually corrode off. Easy and simple to replace.

    Part list if you want to make your own:
    1. Temco 4/0 welding cable
    https://www.ebay.com/itm/2822085349...2fXpNIpQmm&var=&widget_ver=artemis&media=COPY

    2. Ring terminals
    10pcs 4 Awg - 5/16" (M8) TKDMR... https://www.amazon.com/dp/B08R6Z38C4?ref=ppx_pop_mob_ap_share

    3. Rosin core solder. Get the thick kind. Thicker better.

    4. Utility torch
    https://www.walmart.com/ip/17128613?sid=e1ad3291-b48c-4022-844c-9e0158d479f8

    Use a locking vise grip or a table vise. Lock the ring terminal in. Heat up the ring terminal. Melt in the solder core up about half way the ring terminal. Insert stripped welding cable in to hot ring terminal. Let cool.. add heatshrink with adhesive inside. Heatshrink tube from #2 above works just fine. Cut it in half.
    Done.

    Actually that is the proper way. You shouldn't solder large diameter wire. Crimp and use heat shrink. Heating the wire and soldering will cause the wire to fail as it wiggles and moves.
