it looks like we are going to have to wait to upgrade to a newer MH so I would like to upgrade the Turbo Hydramatic 400 to the 700R trans. Has anyone done this here? Seems at 65 mph its topped out, so...
Thanks Dave, that is another great option. I've also read of a standalone GM 4L80e controller used on early '90s diesel p/u's that can be retrofitted fairly easily. I like the Megashift since it can be integrated into a DIY Megasquirt EFI system later down the road. Plus there is a lot of developer support on the web. Just cool stuff to think about!
