1G Transmission Motor Mount Stripped

[bgold87]

What's up all, getting my engine put back in last on my M/T 6 bolt, and I stripped one of the tranny motor mount bolts. The bolt that attaches the mount to the transmission. What's the best way to fix this? Helicoil?

Also, the bolt I have for it look really small, does anyone know a part number or what size they are?

Thanks!

1G Transmission / Motor Mount Bolts

Heli-coil, TimeSert, some other type of thread repair insert. There's also the less popular swap cases or weld it up and re-tap (would not personally recommend doing so without disassembling first).

I've Heli-coiled the mount threads on my transmission before and it has held fine for over 20 years now!

The bolts look really small? They shouldn't. If you are talking about the vertical bolts that go into the aluminum of the trans case, those are M12 bolts. Big.
I've seen a lot of cases where a transmission builder or installer will replace those bolts with studs that are pointy-ended on top. (Mine for example)
If the bolts in yours are smaller than 12mm then somebody has already done something like putting a threaded insert in there with an ID for a smaller bolt.
