Looking at the parts diagram what is the correct part number for the transmission cross member? Reason for asking is that 3 of the 4 weld nuts that the RCI skid plate bolt to have snapped, the two on the passenger side snapped a few months back and I had to drill up through the cross member and insert longer bolts to attach the skid plate, the outer one on the drives side snapped when Toyota was working on my 4runner and the inner one isn't too far behind. The drivers side has a larger oval opening on top of the cross member so I can't drill new holes and it's near impossible to try and wiggle pliers and a nut into place enough to try and fasten to (I have small hands but not that small).

So that's why I'm asking.

A nutsert is possible option but I'm not sure what to even order on that end.

What are the bolt sizes that have broken? Most of my skid plates are attached with nutserts at this point. The Astro 1442 works well up to M8, but you'll need an 1452 for M10-12.

I'm very diligent in using ample amounts of antiseize on all of my skid bolts these days.

Bumping this thread because I cannot for the life of me track this part number. I tried last year and found a Japanese diagram saying the trans crossmember is “not serviceable”. I can’t for the life of me figure out why considering it unbolts pretty simply and I see them pop up on the wrecker sites on eBay all the time (which will likely be my route).

What possible reason would this be unserviceable for?

Every major parts site shows it on the diagram but when you scroll through the list it skips (#6) the trans crossmember every time.

Getting ready to order skids but I trashed my crossmember on a rock a year or so ago. Just pulled off the damaged “Suspension Support - Toyota (51225-35040)” to see if I could possibly work with the damaged crossmember. It’s pushed in quite a bit and I no longer trust the welds on the nuts (where the support and skid plate will mount up.

Any input is appreciated.

Also the fug is the deal with this mount? Do I need a special tool to remove it? Or is it just a simple screw?

Think my plan is to unbolt it from the trans and drop it with the crossmember. Remove it from the damaged crossmember off the vehicle, then transfer it over to the new/used crossmember I end up purchasing.

Again any input is appreciated.

Edit: It holds the two haves together should the rubber on the mounts fail. There is a hole in the cross-member the plastic nut protrudes through. Only removing the 4 bolts from beneath is required to separate the mount from the cross-member. You don't mess with the plastic nut.

Found a decent one on eBay that wasn’t crazy rusty. Went ahead and pulled the trigger.

If anyone has an idea of why they call it “unserviceable“ I’m all ears.

If anyone knows if I need a tool for the mount screw plastic nut doodangle I’m all ears.

I’m off to order a replacement support dohicky.

*solved* Transmission mount please advise.

Info relevant to trans mount for anyone reading.
