Buying A Used Transfer-Case Or Transmission

Posted in How To: Transmission Drivetrain on April 24, 2014

Buying a used T-case or transmission is kind of like buying a used Jeep -- only when buying a whole used Jeep, a lot more bad stuff can be hidden by a deceitful seller. That’s not to say that T-cases can’t be made to look better than they are, but generally no one’s gonna retire in the Bahamas by scamming people with dubious used T-cases. The fact is that if a transmission or T-case turns and shifts and doesn’t have any weird leaks or a cracked housing, it’s probably alright and at worst may need a rebuild. If it’s cracked in half, it’s probably good for nothing other than a few possibly salvageable internal parts. As with anything, you need to know what you are looking at and what you are looking for. We have been playing with transmissions and T-cases for a long time, and we have a fair idea of that to look for when buying a new to you used gearbox.

Unfortunately, even cast iron T-case housings can crack. The other problem is that it is often difficult to see the cracks until after you’ve torn the case apart and cleaned it up. If that happens to you, know we feel your pain. Some day we may tell you how many times we’ve gotten either half way, or completely through, rebuilding a T-case before we noticed a crack. When looking at a either a T-case or transmission, keep your eyes peeled for cracks and odd leaks.
