Did you find out what the pulse rate is for your T/A yet? It might be a simple way of getting Autometers pulse rate converted over to the T/As. If not you might have to go with an Autometer electric speedo if you want to keep the TH 350. Another option is to upgrade to a 4L60E tranny in place of the 350 guy.
