crackes flex plate - any ideas ?? -(finally fixed)

[chasone64]

I have a 350 with a th400 & a 203, and a cracked flex plate...
I have a tranny jack, but I don't know if I can ballance the tranny & case on it. I was thinking of dropping the case & then sliding the tranny back to get it out, but that's a lot of work.
Has anyone tried sliding them both back with a jack??
What about an adapter to hold them both??
Just looking for ideas...
Thanks

I slid them both back.

It is a pain in the @$$ to lift them back into position if you don't have a second jack.

After a while I just borrowed the neighbors.

slid mine both back together. I dropped the cross member with them and used it as the jack point. It was still front heavy but nothing I couldn't handle. Make sure you support the motor.

Get yourself some long bolts with the same thread and diameter as the bolts that bolt the tranny to the block. Thread one into each side of the tranny, support transmission with a floorjack. Remove crossmember, and shift linkages, unbolt flexplate from torque converter. Slide the transmission back on the jack and the long bolts threaded into the block. At this point you unbolt the flexplate from the crank and replace it. Then push the transmission forward and reatach everything. When I did mine, I didn't even have to remove the drivelines.

This will be the best way. Or use your tranny jack some chain and a couple buds to drop the tranny/t-case and re-install. Its a real beatch!!

This is a great way to do it. Just run the bolts from your starter into the lower bellhousing holes and slide it back.

That's what I was thinking, now just to get some time off from work to do it...
Thanks for the info

Back on the road...

Well finally got it done.
What a PITA, prev owner used four different sized bolts in the tranny crossmember, wrong bolts for the flex plate to torque conv.
Took some looking, but my friend had the correct bolts.
