I've rebuilt 350's and 700's many times,usually it's abuse that bum's them out. But most of the 700's have more room for additinal clutches, wich I put in at the rebuild.Them seem go last alot longer as more clutches mean more durability.Also I recomennd changing out the tourque converter at the same time,I've seen a few failures because of this.Actually had one guy wanting his money back but said he didn't change the converter!I just say to bad for you,but pulled the tranny apart anyway,found nothing wrong, got the converter stuffed it in and no more problems! lesson learned to him, but glad it didnt burn the thing up again.
