This is really loud, dunno if you saw the video I linked.Often when a metallic skid plate is added to a truck that didn't have one, the noises the truck already made become amplified. Often a noise that was unnoticed becomes noticeable.
The 10r80 transmission has 2 fluid pumps. One for when the engine is running (gear driven) and one for when the engine is not running (electric).
The gear driven pump is fairly notorious for whining at various levels. Some are quiet enough that you'd have to get close to it to hear it over the typical truck noise. Others whine so loud that the truck owner and the warranty technician agree that it's not something you should live with. Then there's all the ones in between, that a metal skid plate would amplify.
If you saw a 10r80 transmission sump cover dropped and got a look at the plastic cover that surrounds the gear drive, you would understand how there's such a variability between trucks and how much noise/whine that pump can make. The plastic shroud doesn't have sufficient integrity of its own to ensure its not going to rub up against the gear itself. A bit aggravating considering the 10r80 is in its 6th year of production and Ford has had to warranty many.
By the way, it could be whining horribly and still be functioning properly. The plastic whine has little/no impact on the pump functioning.
I just measured the thickness of the skid plate + cross member and it is 58mm. I’m going to try 80mm bolts.I went with M12-1.5, 90 mm in length. Stainless as well. Must be careful about cold welding/galling with stainless, be sure to use anti-seize or lock tight. I can post back once my bolts arrive - hopefully this Wednesday.
Nice! Let us know how the new bolts work out. If they are good I will probably preorder them myself.The 4” bolt was making contact with the transmission heat shield (guessing that’s what it is). Definitely need a shorter bolt.
May still have to bend the shield a bit to make room. Did no one else have this problem?
I have not, but I don't normally drive my truck long distances all that much. I will check though. Is that the drive side back or the passenger side back (can't tell if that is the heat shielding on the bottom)The 4” bolt was making contact with the transmission heat shield (guessing that’s what it is).

This was on the back passenger’s side.I have not, but I don't normally drive my truck long distances all that much. I will check though. Is that the drive side back or the passenger side back (can't tell if that is the heat shielding on the bottom)
I think mine was almost wedged against it. If you find a shorter bolt works, I think I'll swap mine out to be sure.
One note, you mentioned stainless. Is that more resistant to the galvanic reaction with aluminum or are you just looking for weather protection (something I need to worry about as well in FL). Thinking you could probably get a nylon washer if that was the case.
Love the roll over video!Got mine installed today. Pretty straightforward, only issue I had was on that same passenger side rear bolt but mine wasn’t too long, that heat shield got in the way of letting one of the big fender washers sit flat on top of the crossmember (which is needed as the hole is too big and the nut will fall through.). Easy fix though, just loosen the bolt holding heat shield, which allows you to push it up, then you can drop the washer down and put the heat shield on top of it. Once both are tightened back up it’s solid as can be.
I do not have my plate yet, no truck yet, but look into a Fumoto valve with a nipple for a hose or this:How have oil changes been with these? Looking to possibly buy one.
