WRANGLER 95-02 3 SP RWD/4X4 L6 4.0L 32RH A999 Tom - the above is the Data I gleaned off www.google.com . The A-999 is : RWD = Rear Wheel Drive 4X4 = comes with a transfer case This is a non-electric trans. as it doesn't have an 'E', say 32RE - instead it has the H being Hydraulic operation.
The A-999 of newer vintage is a much refined item over the old 904s and comes with HD parts whereas the 904 is very light weight.
True... but I'll have a 258 with 1bbl or 2bbl and 2" exhaust. THe hot cam will come out and stock or "RV" go in, so even a stock 904 should be plenty strong. The rebuilder suggested solid 2nd-gear band and other changes, I'll talk it over with him regarding $$$.
That said, there is a goodly stock of A-999 transmissions with low mileage on them - just do the contacting and speak with the yard. Many of the yards have been with www.car-parts.com for years - so ask about any 90 day etc. return policies up front.
