[Spridgets] Speedometer cable?

[Robert Weeks]

I finished up my transmission transplant on Saturday and everything is 
working great except for the speedo. I reconnected the cable to the 
transmission after the transmission was in the car so I can't see how it 
is mating with the speedo drive but it feels like it is correct. When I 
detached the cable from the back of the speedometer it is not turning 
while I'm driving.

Is there any trick for getting this right or is it just a try, try again 
type of thing? The speedo drive worked on the transmission before I 
removed it from the other car so I'm thinking it's how I attached the 
cable that has to be the problem.

Other than that the replacement transmission is working perfectly.

Thanks,

Robert
