Bellhousing leak bellhousing is leaking when vehicle is running

Did you just have the fluid replaced in the transfer case?? if the answer is no, the you may have a leak from the series of seals that are internal. you will have to have the transfer case removed and have the CVT seal replaced and other seals inside of the transfer case. lengthy repair and costly also. the transfer case has to be removed to replace the CVT side seal and while you are in there replace seals inside of the transfer case also. that what its sounds like to me. transfer case seal leak or the inside CVT seal leak. however if its leaking right from the bellhousing, it also could be the torque converter seal. this is when proper diagnosis comes to play. if its d converter seal, than the trans has to come out. have this one checked by someone that knows what they are doing. could be transfer case seal leak and it could be converter leak.
