Transfer case leaking out the speedometer gear

Pull and recheck. O-ring could be not seated correctly or split.

X2 probably seated incorrectly. Pull it back out and try again

If you didn't do the swap yourself, it's not impossible the mechanic forgot to put on the o-ring, especially if you are really leaking as opposed to a slight drip.

Either way, you need to pull the speedo-gear and check if it's not seated right, missing, or perhaps damaged during the install.

Funny story, the previous owner of my jeep decided to save some $ and put silicon around the speedo-gear instead of using an o-ring. It didn't leak, but what a mess it was to remove when I put in the right size gear.
