TH 350 case

The 4WD case accepts a cast aluminum dust cover and is a bit stronger in that area but the bellhousing area isn't much stronger. Any time you lose a driveshaft, you can almost guarantee the case is going to be cracked. Stronger alternative is a JW or ATI bellhousing, or ATI case with bellhousing. Internally as long as it's an early, non lock-up TH-350 and not a TH-250, which includes an external adjuster for an intermediate band, cases and internal parts are fully interchangeable. Also 6", 9", or 12" tailhousings with the appropriate output shaft.
