72 K10 Manual to Automatic Conversion

[MikeandCheryl]

Thinking, at this point, of making the truck more driveable for the better half. Thinking of an automatic transmission and transfer case to replace the SM465. Anyone have any experience with this? Pros and cons? Looking at a more modern engine/trans combo, wondering if both front and rear ends will need changing to suit the gearing/alignment difference. thoughts? It seems like more work, however if all my drive train needs rebuilding, costing gets closer. Resale? Drivability? Reliability? tx.
