1989 one ton (old body style) VSS code

[ahawes]

I've got an 89 crew cab one ton that I am getting a SES light on and every time I run the code it comes up as a 24 which is the VSS. My speedometer still works, odometer does not. My question is this - with the VSS code is my issue more likely the sender on the transmission or the unit behind the speedometer? Or is there any way to know? I realize the VSS doesn't control a whole lot with the motor or PCM but the perfectionist in me just wants to keep the SES light from coming on. Any help or suggestion would be appreciated!
