A friend and I hole-sawed his S10 Blazer's firewall to get to a bellhousing bolt. Then we did it again, a few inches over, because that's where the bolt actually was. Not our finest moment. (Or Chevy's finest moment, either, but that's the S10 for you.) If you do go for the hole saw, make sure you measure better than we did. Also make sure the hole saw and/or pilot drill aren't going to take out the harness when they break through. I've got a trans with this sensor in the corner, waiting to go into my '93. I think I just found something else to check before I install it!

Dude...your reply struck a total déjà vu moment...except it really happened! In fact, exactly one year ago, I replied to a thread on the Club Frontier forum about this exact same issue where ATF was unbelievably dripping from wiring insulation. I had forgotten all about the leaking through the insulation, only recalling the general nature of the failure. While I was typing my reply there, the topic starter had posted that he found the same issue on the Club Xterra forum. All these trucks use the same transmission, of course. This post shows the failure at the tip of the sensor. So, my money's on that sensor. Unfortunately, if it is that sensor, it's not cheap and not easy to replace. Unfortunately, part two, I decided to crawl under my truck to see what plugs are visible to confirm if I could see what you see. I see that my harness also shows a layer of grime on it...which is highly unfortunate because I just had the transmission down in 2023 and didn't notice it.
