It's strictly a trademark issue. I just talked to D&D the other day about this and was told they still have quite a few Viper T56 trannies in stock for the foreseeable future. However,they are in negotiations with Chrysler to resolve the problem.
I've got one in my 69 El Camino and it works really well with 4.11 rear cogs.
6th gear is strictly for highway fuel economy.
