Stripped Transmission Pan Hole

[JoeyRig]

@P. A. Schilke thank you for your insight. Was honestly hoping that you'd chime in on this topic. Side-note your comments on this forum have been invaluable, and a great learning experience.

@RangerBill Pulling up the manual was the first thing I did before posting here. Lesson learned the hard way. Thank you!

Everyone else, thank you again. Tomorrow morning I plan to regroup, try chasing the threads first thing then go from there.

These are instructions from PPE.

I ran all the way to the garage to idiot-check myself. ?

These are from my instructions.

Still not an excuse, I knew 18-22 ftlbs was ridiculous but tried it anyway.

Over torque on all the bolts could have also damaged the other threads even if the bolts didn't break. I would check them all. If there is any oil on the bolts when torqued I always reduce it some.

Another option for OP is to use a thread forming bolt if he/she does not have a proper tap and die set. Helicoil kits can also be pricey to do only one job. A thread forming bolt will cut its own new threads into the soft aluminum as you screw it in.

Woah they shipped instructions with bad torque values?! I would be pretty livid. The screen grab I posted is from the instructions on their site.

Those threads were probably thread formed in manufacturing. Most all automotive aluminum die cast near net shape parts use form taps. Much more reliable machine process because of no chips being produced from threading, and you get a stronger thread because its formed. Tap drill sizes for thread formers are larger than those for thread cutting taps.

id be callin the company and asking how many bolts they snapped off!

You’re probably correct. I have only ever used them when supplied by the manufacturer to secure parts in a near complete casting or while doing a tear down/ assembly on already assembled parts.

maybe I missed it but first run a taper tap followed by a bottom tap to clean up the threads

Ok, don't laugh. But before you go too extreme, grab some zip ties. Assume you are like most guys and have a number of sizes already in your tool box. If not, head to Home Depot. And take your bolt with you.

Find a zip tie that is about 1/2 the width of the hole. Cut off the starter/pointed end of the zip tie so that it is roughly the depth of the bolt hole. Insert that piece into the hole. Insert your new original sized bolt, making sure that the zip tie stays upright so it is between the threads and the side of the bolt hole. Gently tighten.

I'll bet you a beer, heck and beer and wings, it will hold. Especially at the low torque values we are talking. Sounds nuts. But it works.

Sounds like a TikTok life hack. Something I would condone on a POS or 20 year old vehicle lol but not on a new truck

I was using that hack long before TikTok was even a thing. Years. Don't even remember who/when/where I learned it. But it can seriously get you out of a jam, and do so pretty easily. While I am a vehicle maintenance freak, if I was in the OP's shoes I'd try it before all of the other more involved fixes.

Would I use it on engine mounts or suspension bolts? No. As with most things in life you have to balance it with a bit of common sense. In this case the torque required is nothing. So I'd totally try it.

Just my 2 cents.

Oh for sure it’ll get you out of a jam it could even last for years and I agree with everything you said. The time to invest in fixing an oil leak down the road instead of fixing it right when OP has it all apart is why I would disagree.

Call the company. At the very least to inform them of their screw up. In my opinion, they should pay to have this professionally repaired and refund the cost of the product.
