Transmission leak?

I recently had my brakes/ball joints/ track bar/ steering drag link replaced on my 2016 Jeep JK that has a 3.5 inch lift.They also did an alignment. The jeep didnt seem to have any issues for a month.With the recent snow I put it into 4x4 high and heared a terrible grinding noise. It continued to make some grinding noises after going back to two wheel drive for a bit then stopped. Since then I have intermittently heard a low grinding noise on the driver side. The differentials have fluid, the transfer case looks clean. Only thing is now I am seeing some fluid on the manual transmission case and the check engine light is on.Could the previous work caused a misalignment issue? What do you all think might be going wrong?

Did you change the oil cooler filter housing? They been proven to be junk. Pretty much ALL of them leak. The oil runs down the Bell Housing which appears to be a Trans leak.

Quick check. Remove the engine cover. Look directly down in front of the filter housing. If you see a puddle of oil. The filter housing is the issue. BUT this has nothing to do with the grinding issue your having. Also, if your oil light is on. Your most likely low on oil.
