On my th400, I just left the gears in it and the cable unhooked. I've got to find an elec adapter but for now it's just unhooked.

so do you still need that gearing and all that even though I'm switching over to electronic gauges?

I have a 92 and it's got an elec speedometer so I need an adapter for mine. If you're going to elec speedometer, you will probably need one to. I've found a few at summit but not sure which one I need. You can change out the speedo gears and install a reluctor wheel and sensor on some transmissions . It would probably cost more. If you're doing aftermarket they will know which adapter you need.

replace the o-ring to fix the leak on your current setup.
