well, I'm new to the thread and jeeps, that is, and I had a question regarding a recent problem with my transmission. I just recently rebuilt my 4.0 motor and my transmission wouldn't seem to downshift to first gear on hills. It eventually went away and for a week it ran great. But after a rainstorm it started acting up again. I replaced the fluid and filter screen, but it didn't help alot. My fluid level is fine and I was hoping for some advice. Thanks
