Having problems with your 1999 Dodge Ram ?
I have a 2000 dodge ram 3500 with a cummins. When driving 45-55 mph it stumbles,misses.,when going under or over that speed it runs normal. Is this a transmission problem?
had the same problem it was a broken OD accumulator piston spring in the valve body. Just buy a transco SK 45RFE shift kit it comes with all the accumulator piston seals an updated and much thicker and stronger accumulator retainer plate AND the kit includes a "spare" set of accumulator springs (1 large & 1 small) in case the spring(s) are broken ,which they do from timt to time. It is only 6 bolts to remove the valve body (carefully) and 7 screws to remove the accumulator plate to access the accumulator pistons and springs. The instructions included in the kit are excellent and very straight forword, you won't need all of the parts but save them they may come in handy some day later.
