I have an 01 Ram that I am in the middle of replacing the tranny on. It is also leaking from the rear main seal. I was thinking about working on that while the tranny was out since i had more room. How bad is it to do on these trucks? I know the y pipe has to come off, but can you get the oil pan out w/out lifting the engine up? Has anyone been able to get the upper half of the seal out w/out loosening the other main bearing caps? Thanks
