I swapped a 92 t5 into my 88 Blazer. I can't hook up the speedo because its a cable the new trans uses a vss. Now I am getting a code 24 vss error.
The dealer says my truck has no vss so how can I get an error for it

You have a VSS , it's on the back of the instrument cluster, right where the cable goes , black plug with three wires ,I believe it was used for cruise control

Yep,even though you have a cable speedo,you have a VSS buffer on the back of the cluster.Its not getting any signal from the spinning cable speedo,thus throwing off the computer.
Did you use to have an auto?Or was it always a stick?
