A repost from the trans/drive train from, cant seem to get any replies over there.


Just putting together my 388ci/700r4 combo, a warm day in the northeast had me back at it.

Wanted to finish up the bellhousing bolts. Luck has it I snapped the driverside lowest bolt.

Im really not looking forward to pulling the engine and trans again to remedy this.

I plan on pulling the 700r4 next winter to have it beefed up (I cant imagine the stocker holding behind this motor very well)

Do you think the 5 bolt will hold aright for a season or shall I pull the drivetrain again?

if ur gonna pull the motor again then i would leave it

 

Some people do get by without 1 bolt in it, usually the top bolt on the bellhousing/engine. Personally if its a half a$$ed job then who cares, but for my car I would rather have all bolts in, so one of those "just in case" moments doesn't occur. So, IMHO do it right or dont do it at all.

 

So what your saying is that the bottom bolts are more crucial then the top.

I read on here somone saying that the pins in fact take most of the force. Is this valid at all?

This is true, when the bolts are tight. I have known people who have run transmissions with one or 2 bolts missing. The problem becomes: you can't keep the rest of the bolts from loosening over time no matter how tight they are put in. When they back out, witness the "bellhousing explosion".

 

if all the other bolts are tight and you dont beat on it it should be ok. but if the other bolts come loose you take a chance of cracking the bellhousing and wasting it. if its the lower bolt i have gotten them out by loosening all the other bolts just enough to get a pair of needlenose plires between block and bellhousing and backed out the broken bolt. as long as you didnt use to long of bolts and bottomed them out in the block.
