'97 M1097a2 4L80e is bad. Need advice - DIY rebuild or junkyard swap?

[TNDRIVER]

Ended up taking the overwhelming advice and dropped the trans off at a shop to be rebuilt. I'll know what we're looking at within a week.

Interestingly enough, I found out this '97 M1097A2 has the MP2225 transfer case. One of the coolant (antifeeze) lines going into it is snapped off, and I've found more loose/missing bolts that indicate this truck was slapped back together with a bunch of random parts before hitting the auction. Sure hope this transfer case is still good!

You may also find that you have a 4l85 not a 4l80. Some were bought for rebuilds at Texarkana. I've never been able to figure out which ones though. The most telling item will be a 5 gear planetary. Please keep us informed on what you find.
