Its a 5.2L with a 242 transfer case. First of all it runs great.. shifts great and drives great.. My problem is its leaking in between the transmission and transfer case pretty bad. I installed a used transmission i got at weaver. After putting everything together and running it i noticed a good leak in between the trans and transfer. I replaced the rear main seal on the transmission with a seal from napa, still leaks just as bad. Then replaced the rear main seal on the trans and front seal on the transfer with seals from the dealer, still leaking bad. Its def transmission fluid now.. So what could be causing this?
