Thank you for the replies.
Is this piece a straight replacement in the newer units or does it require other changes.

Would these fittings restrict volume of oil flow? I want to use just regular fittings not the factory snap in.

At first I thought- yes I am capable of doing a 4l80e, not so much anymore...more so the looming specter of taking the trans out again because I missed something.
Clineberger- I like the idea of the Sonnax reamer and sleeve- does your shop have these, could I ship valve body for service. I cannot justify buying that particular kit and don't like the wearing characteristics of the cheaper technique.
The damaged oil cooler lines were not on a Allison trans, and yes this is a cold climate here, I just didn't see the cooler lines as a maintenance item. Either way I think hard line is a lot of work but a good quality hydraulic line will fit the bill.
