The 48re in the qc srt-10's was interesting to say the least. It was fun to see more of chrysler's trying to do something a little different and causing even more problems. I had heard the v/b had a different spring for the limit valve in the part-throttle kickdown assembly, this turned out to be false. the 48re v/b in the srt and diesels are exactly the same. Actually, besides the braces on the overdrive and the torque converter, they are exact, except for one very important thing, the frt servo. On the diesel, they use the spring from the 47re, v-10 truck or diesel, in the frt servo. In the srt, they use the spring from a 318-360 46re/rh transmission. Also the frt servo itself has a much larger apply and relief hole in the bottom of the piston, where the diesel has a very small side drilled apply and release. No damn wonder these things are literally cooking frt clutches. This was chrysler's attempt to help the 6000rpm gear changes and, in my humble opinion, shot themselves in the foot. The only other difference was that the accumulator bottom spring is not there from the factory (mistake) causing the plastic accumualtor to literally smash itself against the v/b on upshifts. I talked to one of you on here about this and I thought at that time that there should be one there and there is not. They did however use a spring somewhat like the 42re in the 3.9 dakota on top of the accumulator. Everything else is exactly the same, including lube circuits(hint-hint), yes that is for you STINKER.
Don't worry JEFF, your accumulator is no longer plastic or without springs. Hope I have helped. It was fun to see what the factory did so we could do an autopsy and hopefully correct the conditions.
