So i got my tranny almost on and its on the dowel pins so i put in the top tranny bolt to snug it down against the block and SNAP the bolt breaks off!

So what do I do now???
 
Alright thanks Ricky this tranny is being a bi*** to get on
 
You can remove the motor mount from the passenger side, that will atleast give you clearance to move the tranny up. While doing so get the tranny on the rear mount and then bolt it in. It's much easier that way. Try to steer away from using the bolts to pull the tranny and block together because the transmission may get held up on something and in that case you will continue to snap bolts. It's also helpful if you have a second person there.
 
just took the tranny back off and the bolt it broken from inside the block. theres no way to get to it...
 
im just going to get upgraded bolts all around and run it without the one bolt. The motor is stock and I have the one im building on the side so its only gonna be somewhat temporary

I don't know if I would do that honestly, and if you do decide to go that route. Don't drive the car rough. It'll probably be okay.. but why not just pull it apart and take it to a machine shop, that would be cheaper than building an entire block. You don't have to disassemble the block. Just make sure no dust/metal get inside the motor itself.
 
You can weld a smaller bolt to the end of the broken belt and hopefully the heat expanding and contracting the metal will allow for the piece to be backed out. Otherwise drill and tap (ugh)...

Not only that, but I've seen people crack the bell housing.
 
I dont have a way of pulling the motor tho..

Well im building another block cause i dont trust the stock block with all the miles and I want something more reliable with the power im gonna be pushing

I'm simply saying, that if things go wrong with running without a tranny bolt, which will happen at some point, this is the beginning and the position to avoid having to replace more than just a bolt.
 
For what its worth.. when I pulled the motor out of my colt I found out that my trans was being held to my motor by only 2 bolts.

I have over 50 timeslips from last year... can't believe nothing catastrophic happened because of it.
 
Ask Jafro if this is a good idea.

To OP and anyone else that ever reads this for help: This is NOT a good idea. There is only one circumstance where leaving a trans bolt out is acceptable, and that's using a 2g tranny on a 6-bolt block. One hole will never line up in that situation, but otherwise you must have all of them in place including the "hidden bolt" on the other side below the alternator.

Every bolt needs to be in place and torqued to the proper spec. If not, more bolts coming loose. The uneven tension across the bell housing flange, coupled with heavy-duty clutch hydraulics will allow those heavy parts to rock back and forth every time you mash the clutch, and slowly back out all the other bolts. Especially if you have a heavy-duty clutch.

Once your clutch is misaligned from this problem, say goodbye to your rod bearings and thrust bearing. It's a short matter of time before you'll need a new transmission, shortblock, or both.

I learned this the hard way. I bought a car that never had the "hidden bolt". Blew up 4 transmissions and a shortblock before discovering that other people's cars "were different than mine". I'd been in CAPS, service manuals, etc... it simply isn't covered or clear in any documentation.
