Default 85 C4 Manual 4+3 Doug Nash Overdrive Issues

Does anyone owning the 1985+ series C4 Corvette with the Doug Nash Manual 4 + 3 Transmission with OD, have one that downshifts smoothly when coming to a stop? Mine up-shifts OK but the downshift is not smooth and generally results in a pretty significant bang or clunk. If you have any experience with this transmission and can provide me with helpful information, please email me directly at: w1wlh@earthlink.net.

Thanks,
Bill
