the 'hard shift' is probably a very easy fix--full fluid flush, add 1 pint of LUBEGUARD RED (good auto parts stores have it.) It provides the proper clutch lock-up smoothness. Absolutely the BEST thing for any tranny using Dexron fluids (not Type F fluid).
A better way to test the suspension accumulators is to do what I call the 'curb drop' test. Drive one wheel up on a 6"-8" curb, then back off quickly 'dropping' the wheel on the pavement. Note how well it handles the bump. Repeat for other 3 wheels. A good accumulator will give pretty good bump control, no harsh jolt or wild bouncing. A bad accumulator will give a hard jolf and reallively rapid bounce.
Read all about the ACH system on my website (activesuspensionsystems.com) Note the AHC hydraulic pump is prone to failure when it is hot. Try not to ask for L to H movement when it is hot, and try not to carry heavy loads when it is hot. Once the pump gears touch and it begins to make any noise, the useful life is minutes of operation.
