I put a 2002 Chevy engine,trans.(4l60) and computer into a 68 Chevy truck. I want to keep the orginal dash cluster. The trans is setup with for a electric speedo. I need the electric for my computer but I also need a cable for my 68 speedo. Any Ideas? Was told that some caddys trans. were setup for both, mechanical and cable. So I could just swap out the tail section. Are they ? I thought about geting a electric speedo gauge like autometer,SW,
etc. and transfering the elec. parts to my 68. or just changing the faces. Anyone run into this or have any ideas? THANKS !

You will need an electronic speedometer. The original analog speedo used worm gears to turn the speedo cable. The output speed sensor is in the worm gear position of the output shaft.
Change the speedo mechanism to a late electronic one.

whynot,

you are up against a hard spot here. There is no hole in the output shaft for a clip that holds the plastic speed-O gear on.

www.jagsthatrun.com have a clamp on retainer assembly that will hold a plastic speed-O gear in the correct position on the out put shaft.

Look through their web site for information.

if the tail shaft is the same diameter as the muncie they have a steel pressed on gear that would work, with out needing the hole for the clip.

After changing to a manual speedometer gear you could then get a speed sensor from Autometer that screws onto the speedo gear output, your speedometer cable then screws onto the sensor.

the problem here is the tail housing of the 2002 4L60E does not have a set up for the mechanical driven speed-O.


It is a 6 bolt tail housing design ,to my knowledge nothing swaps on for a mechanical speed-O that GM built

It will need to be a custom setup is why I suggested looking at the jags that run site.
