The speedometer in my 91 300zx TT with automatic transmision and air bag is acting up. I followed the repair guides and now it works but reads 10 mph when I am going 55. I am good at working on the car but I can't figure this out. I posted in the wanted section for an instrument cluster. Getting a replacement isn't much of a problem for cars equipped with a manual transmission. But... mine is an automatic and I have not been able to find a part from an automatic. The speedometer head assembly is out of production, but the part numbers show that there is a difference between 90 and 91 model years and 92 to 96 model years. It is not so clear about manual vs automatic. My question is whether anyone knows for certain if they are compatible. I'm pretty sure that someone in this community has had the same problem and knows the answer. Thanks for any help you can offer!
