tranny problems
 
I had the front bearing in a 37 lasalle box lock up and that big heavy gear shift stick was beating the steering column and my leg ...the bell housing was scattered along the road. in a lot of little pieces.

what vehicle?

broken bell housing from chassis flex, broken engine mounts, vibration , broken trans mount, abuse like desert jumping a truck.

I would check driver side engine mount, and the trans mount if the trans mount is good leave it if the driver mount is good or bad change just that side to a solid mount (DRIVER SIDE ONLY) and also check the drive shaft make sure its not to far into the tailshaft of the trans. And also check for proper pinion angle on the rearend. I am thinking it is from engine flex. I bet it busted from the starter around to the other side am i right? Hope this helps Cole

right on the way it cracked. trying to get some picks up. the front mount is almost solid its a fairly stiff rubber plastic material. and the trans mount is a energy suspension mount. drive shaft is not to long, but i am getting a fair amount of wheel hop and axle twist on launch drive shaft hits fuel tank,


what are my options i have seen replacement bellhousing but you have to cut this one off and the new one mounts to the front pump. any opinions

Are you using the front mounts by the timing cover, or the mid mounts under the second exhaust ports?
Bellhousings typically break when you use a front mount and a trans mount on the tailshaft of the trans. Hanging all that weight from the far ends puts too much stress on the bellhousing.

These style mounts are supposed to be used with the trans mounts that are on the bellhousing.

front by the timing cover and the tail shaft mount on the trans. it was like this for 8 years and never had a problem till i rebuilt everything. i am getting my camera will get pics up right now.

Here is your problem.
http://i463.photobucket.com/albums/q...7/DSCF0081.jpg

You need midmounts. It took 8 years to break your your bellhousing, some last longer than others.
The midmounts are closer to the center of the weight of the block, which takes the stress off the bellhousing.
It's been a well known problem for many years. The frontmount motormount was designed to use a transmission that was mounted at the bellhousing. All of the stock applications that used the front mount were set up like that.

I have thought about making some reinforcement bars that went from the block to the trans for those who don't want to use the right mounts, but never had the opportunity.

i cant use the side mount no room because of the steering.

can i just buy the mount plates that go between the block and the trans, that mount to the frame. i thought befor i put it in there the fist time that i should have but i think i will now.

You don't want to mount the engine/trans in 3 places.
I'd either figure out a way to fab a custom mount from the frame to use the mid mounts, or make some reinforcing bars to go from the trans to the motor. Even if you picked up 2 or 3 pan bolts on each side of the pan and motor and bent up a piece of 5/8 solid rod to bridge between them it would help.

Also I would investigate curing the wheel hop and axle flex as when that happens it places an incredible amount of stress on the drive train which shows up as broken motor mounts and bellhousings..
