    #1= What is the best way to get my speedo to work, the t-56 has a speed sensor can I just put my gear off my saginaw on the t-56 shaft and run the old speedo cable.
    #2= What is the best way to run the reverse lockout just hook it to a toggle switch?
    Thanks for your advice,

    the VSS on the T56 is not gona run your cable speedo, Id just run a aftermarket digital speedo

    The reverse lockout can be removed completely & just make a block off plate. Or wire it to a toggle or wire it to the brake light switch

    I've heard way too many people who were unhappy with the Cable-X. FWIW

    I used an electronic speedo from VDO.

    I wired the reverse lockout to a rocker switch that's on the console, right by the stick. Sure you can take it out, but the T56 WILL go into reverse if you miss the shift from 4th to 5th.

    Good to know. I've only talked to 2 guys, who were both happy.

    I plan on electric speedo too. VDO, actually.

    If you leave the solenoid in the trans and do not hook it up it makes selecting R tough. You just have to muscle it in. One of these days I might wire it into my brake lights, but then again I might not. It really works fine the way it is. No worries about shifting from 4 to R when banging gears.

    It took me around 5 years to get around to hooking up the reverse lockout. You really have to push to get into reverse, but it was manageable. If you take the solenoid out, that spring pressure is lost. Since reverse is fully synchronized, unlike older transmissions, it generally will drop into R at 50mph from 4th, with just the slightest grind. I've done this once or twice when I've forgotten to turn the switch off.

    I bet that could be quite the surprise when the clutch is released......

    I hope his clutch slipped. haha

    That's why if I do it, I'll do it wired to the brake light switch.
