Question for you tranny geniouses
I was rebuilding my tranny, and I was torking down one of the bolts on the , I want to call it a throttle body...(its that contraption that sits up inside the oil pan with all the little valves and springs and what not in it), anyone I was tightening one of the bolts that holds it together and it told me to tighten it to 45 inch pounds , well I did and the thing snapped. How big of a problem is this ? Can I just leave it like that or is it neccasary for ALL the bolts to be in? Can I just jb weld the head on or do I not need to worry about fluid leaking out through that hole ? or do I need to go through all the bs of trying to pull the stub out and get a new bolt, btw the bolt is only about 5/32 thick so it would be a major pita to try and remove.
Thanks again guys, hopefully I'll get some GOOD news for a change :p:

Re: Question for you tranny geniouses (Anar76)
I'm not a tranny expert but I deal with hydraulics and I'd guess your gonna need to get another bolt in. Mainly to seal the valve body so you don't bleed fluid between the gasket and valve body. But then again maybe not depending on the bolt position and how much fluid pressure is involved in that area. Sorry I can't give you a definitive answer, Good Luck.

Re: Question for you tranny geniouses (Anar76)
Personally I'd remove it and stick another bolt in. You can bet your bottom dollar that if if didn't need to be in there, the factory wouldn't have put it in there. You did tighten it to 45 inch lbs and not 45 ft lbs right? :p: I just find it strange that the bolt broke under 45 inch lbs of torque unless it was that old and weak.

Re: Question for you tranny geniouses (bence13_33)
Yes bence... it was 45 inch pounds :p:
I find it strange too, the bolt looked good...maybe my torque wrench is broke... I've never dealt with inch pounds so I don't know what ammount of strain 45 inch pounds feels like. after I broke that bolt I said "f" inch pounds, I'll just tighten them, think it'l be a problem ? :)

Re: Question for you tranny geniouses (Anar76)
I don't usually worry about inch pounds. Valve cover bolts are supposed to be tightened to 90 inch pounds if that gives you any perspective. With 45 inch pounds I'd probably just take a rachet and snug the bolts down being sure to not over-torque them. That's just me though.

Re: (45ACP)
You need to get it out by all means!!
You have a lot of hyd. pressure in there and lots of high temps. Odds are it will leak eventually if not immediately. When it does, something is going to shift weird, try to shft two gears at once, or slip and burn up clutches.
Not good. Much easier to do now than on your back with ATF dripping in your face!
Stand the trans on end if you have to drill it out. It will cut down the chances of getting shavings deep inside the trans.

Re: (Anar76)
I'm with 427HotRod on this. "Loose Valve Body Bolts" are one of the biggest causes of troubleshooting items listed on the B&M Shift Improver Kit's Troubleshooting page ( http://users.erols.com/jerryp58/corvette/BNM7.jpg ). I would think that one missing bolt could cause all kinds of problems.
FWIW, I know how you feel. I did the same thing. :bb I was putting the kit in without a torque wrench (didn't have one that read that low). Anyway, I snapped a bolt off. I took the valve body off and was lucky enough to be able to get a set of vice grips on the bolt and get it out. After I went to Sears and bought a new torque wrench, I got them all back on without any problems.
I know it's a pain now, but I think you'll regret it if you let it go.
Good Luck!

Re: Question for you tranny geniouses (Anar76)
More than likely the torque wrench you are using is out of calibration. If its a *** make I would just sh-t can it and buy somthing good. And most of the guys are right in this one you have to remove the busted bolt. pressures in the valvebody are crictical to correct trans operation. Think of the vavlebody as the brains of the trans. If you had a leaky blood vessel in your head it would impair the correct function of the rest of your body. :smash: good luck :seeya

Re: Question for you tranny geniouses (Anar76)
If it broke with less than 45 in/lbs on it, at least we know it's not in too tight. If it's not crossthreaded, you should be able to take a real sharp center punch and tap around the edges to turn it back out. Once it comes out a little use a small pair of vise grips.
You might try a little heat with a propane torch and then spray it with WD-40 while it's still warm. (get torch out of the way first..makes a good flamethrower!) The oil will draw in past the threads and help it come out.
Only if all this doesn't work go to the drill and easy-out routine.

Re: Question for you tranny geniouses (427Hotrod)
Wow I got lucky.
I took it apart and there was a small piece of the bolt sticking out , and I mean small.
I put my thumb ontop of it and turned my thumb and the screw turned with it, It came out very VERY easily, not tight at all, must have been a bad bolt :confused:
Owell, gonna pick up another tommorow and get this thing done.
Thanks for the help guys :D
