There is a guy on IRV2 forum that pulled his trans for a rebuild.
He used the jacks and an 8 x 8" to raise the MH up high enough to get the trans out. It didn't look that hard actually- drop the drive shaft and then unbolt the trans and slide it back to get at the converter bolts and after that- drop the trans out with a HD trans jack.
There is a guy on eBay selling an improved "leak proof" rear seal for the 5.9B and that seems simple to replace.
If $1900 seems excessive to you(I think so too) then You can do it your self and I will do mine when and if it starts leaking.
Google "replacing the allison MD3060 trans".
