I have read that although the modem Dexron superseded the older versions the newer product is thinner in viscosity. Just one of the reasons the new product is Dexron IV and not Dexron II. All part of the mileage improvement game. I have no idea whether this would make a difference in an A833. What I put in my A833 at the last service is Pennzoil Sycromesh fluid.
It shifts really nice. Part of the recent service was a clutch change and with that I spent some time with off set dowels and really dialed in the bell housing, went through the shifter linkage and there is the new clutch, so there are several other improvements also.
