Transmission Pan Replacement

Spent the weekend following Fortech's awesome DIY instructions for the transmission drain/refill on my 2006 Prerunner TRD Sport.
Everything went great, except I noticed the f****** stealership mechanics cross-threaded the drain bolt. Pleasant surprise. Pretty annoying since the truck has always been service at Toyota.

Question for all of ya:

1. Should I try replacing the drain bolt or should I just replace the pan? The existing cross-threaded bolt just spins on the pan when i screw it back in... i have a feeling that the threading is also jacked on the pan, but I'm not sure.
2. If you replace the pan with the gasket, do I need to use RTV to keep the gasket on the pan to help with the installation? Are there any tips/tricks for the pan replacement?

Aside from the pan, gasket, and a new drain bolt, is there anything else I should pickup?

Gasket #3516860010
Pan #351060C010
Plug #9034110021

Appreciate any feedback

Cheer!

 

No sealant, just dry and wipe clean. Consider inspecting your pickup screen while its off. Becareful with the 10mm bolts, they can strip if overtightened.

 

PML sells a deeper pan. I was lucky enough to get one of their promo pans almost a year ago. It added about 2.5-3 qrts of extra fluid.

 

Remember that the torque specs for the tranny pan bolts are in INCH/pounds, not foot/pounds. Def don't want to over tighten those. I used a Wheeler FAT wrench which is basically an screwdriver type 1/4 torque wrench that measures in inch/pounds when I did my pan drop to replace the filter. Oh yeah, since you're dropping the pan anyway you may as well replace the trans filter in there.

 

On the trans pan drain plug, there is enough meat to tap it out to an

$13 M12x1.25 mm Self-Locking Nylon Insert Hex Lock Nuts, Pack of 6

M12x1.25. I used a 27/64 drill to drill the old threads out.

 

retap the plug hole to larger size like dtaco10 says, you may still be able to use the OEM washer, if not get an equvilent at the hardware store, if that don't work then its new pan time. also those bolts are 15 ft/pds torque and the can strip out very easily that's why they incorporated the oem crush type washer to try a reduce the stripping, I would torque to no more than 12 ft/pds to be on the safe side ive did this no leaks and was able to reuse the washer a few more times before getting a newbie

 

I've thought about tapping out, but don't I have to drop the pan if I were to do that?

 

no,

Seem simple enough. I'll give that a shot before spend the $ the pan/gasket.

For the Dorman oversized plug, would you guys swap out the gasket washer with the crush washer? or use both?

 

doesn't the dorman plug come with a washer? I used one of them on a stripped out oil pan.it worked great.

 

The one I'm looking at looks like it comes with a rubber gasket: https://www.napaonline.com/en/p/NDP7043016

 

that will work well.

 

Put grease on the tap to retain metal shavings.

 

at this time id just use the dorman washer, we know it fits the plug right, just torque it no more than 15 ft/pds that's the oem torque on the old plug,
