4L60E Housing Problems

Was just wondering whether anyone else has had any problems with the tailshaft housing cracking. Mine cracked right in front of the trans. mount. I had it welded, and it cracked again, (I think the welding heated the aluminum up too much). Anyhow, I got a new one coming from GM (for a tune of $200, damn crooks) so it should be fixed soon.

What kind of HP figure are you dishing out? Once a car gets fast enough, the Torque Arm mount needs to be relocated to take the strain off the housing.

i am only pushing maybe 360 hp. I have few mods done, so I don't know why it would be cracking.

Thanks for your help!!!

drive shaft balance, bad u-joints, poly mount, worn bushings in the transmission,pinion bearing, ponion angle and bent output shaft any of these can all be to blame.

Are you saying a poly trans mount could also cause this?

Well, The new trans tail housing I had bought cracked again about a week ago. I'm thinking that my driveshaft is outta balance...

So I got a housing coming from 11SECSS, and I bought an aluminum D/S. I hope this solves my issue, if not I don't know what I'm going to do...
