speedometer not working

[edram454]

I had a post earlier about the src (service suspension light) and light would not go off. I was working on my car and I had turned it on and off a few times so the src light came on. Of course all we have to do is drive it a few feet and the light goes off. In my case it would go off and come on again. I didnt realize that the speedometer for some reason stopped marking miles per hour and miles.

the speedo is on and still measuring gas consumption but anything related to marking miles is just at zero. I guess this is the reason why the src light will not go off. the car thinks it is not moving so the light cant clear. I grounded the a-c on the aldl and it listed all the codes, 12,13,etc...up to 43. I think when the light on the src is not cleared it sees the whole system as needing service not just one component. so now the question, what would cause the speedo not to mark miles. This is a rebuilt gauge cluster and it shines bright and marks gasoline usage etc... just not moving miles, no odometer, no mph,, . I tried disconnecting battery hoping it would clear the problem but it did not.

I was told the speedo gets is information via the transmission sensor. I hear it is a yellow and green wire that goes in to the drivers side of the transmission and that is where it gets its speedometer mph information. Have any of you had this issue??
