Few little issues need some guidance on.

So found a small leak on the trans cooler line in the back, pan gasket is leaking a little, but majority of the fluid is coming from bellhousing area i think i didnt coach the torque converter in correctly and causing from seal to leak.

If the tranny front seal is leaking.

You can loosen the 4 converter bolts and with a breaker bar on the harmonic balancer bolt, crank the engine over a couple of turns an then tighten them backup.

Try this ^^^^^ seems to make sense to recenter your torque converter to the trans front seal.
