Thread pitch for Trans mount bolts? 700r4 / 4L60?
Does anyone know the thread pitch and size for the 2 bolts to bolt the mount to the transmission?
Anyone know the nut needed for a stock mount?
I find I can't find my old ones, and I have NO idea what they are. Can't exactly take the transmission into a shop and pick and pull till I find a bolt that fits.
I've read that the heads are 14mm, but I'm not sure about the thread pitch, though a 14mm head sounds right.

I thought every car guy had a Magic Bolt Box. It magically has every bolt known to man, except the one you need, And it magically changes it's contents according to what you need. I have a 5 gallon MBB. But here's a tip. If you can find a spare 700R-4, the bolts for the tailshaft housing should usually work for the mount. You might need some washers. These bolts usually take a 15 mm wrench or socket.

I have mine in hand out of an 85 IROC with the 700R4. M10 X 1.5 x 35mm in length.

These things should be as common as a wrench in every tool box.

Here is another option for measuring bolts and nuts that I have.
