700r4 Speedmeter Help!!

[aboyer]

I purchased a used 700r4 transmission for my truck and had it rebuilt by a professional shop. Since it was my first time installing it in the truck, I wanted to get the correct plastic speedo gears to have a correctly reading speedometer.

I recently purchased the correct plastic gears and have found that my transmission might have been used in an electronic speedo? Can someone look at this picture and tell me if I am on the right path? From what I can tell, you can't remove this metal gear.

Is there any way to convert this to work with the speedo cable on my truck? I already spent a ton on the rebuild and I would like to get the speedo to work correctly.

Thanks,

Adam
