The damn blinking O/D only tends to rear it's ugly head when I drive out in the streets and it never rears it's ugly head when I'm on the freeways...and being that it never blinks on the freeway runs, the possibility of the transmission overheating is out of the question...also, I drove the car for 30 minutes out in the streets and the stupid light didn't come on...stupid VSS.

Good news is that there is a very simple fix to this.

Remove ur cluster, locate the wires going to the Odometer...cut Pink/Peach colored wire in half with some slack. Then locate a wire that is half blue and half red (should be right next to the pink one somewhere)...cut that in half. Then take the Input side of the pinkish/peach wire and wire it directly onto the Input side of the blue/red wire. Then take the Output side of the blue/red wire and wire that onto the 2 wires you connected...solder, heatshrink, blacktape that ***** and enjoy. What this does is bypass the OD to the from the cluster and straight to the ECU...ur car is running like **** right now bc the ECU is now receiving engine speed. I can almost garuntee it that this is ur problem. This will happen even if ur tach is not working.
