Personally, I'd look at the trransmission. Sounds like the converter may be unlocking and/or downshifting out of overdrive. A 1300 RPM difference is a lot. I have a 96 Ram and 1300 is about the difference between overdrive and 3rd. By the way, it's not uncommon for these trannies to fail before 100k.
