Hello all I am new to the forums so I am not sure if this is in the proper section, but I will gladly move this to the proper section if need be. On to my problem. I have a nearly original 1991 camaro rs with the 5.0 tbi coupled to a t5 world class transmission. Just yesterday I converted my instrument panel to blue led illumination, which looks and functions well. While I had the panel out, I noticed that the shift light bulb was missing. Since I had a few extra bulbs, I plugged one into it. Now when I run the car, the shift light only comes on in 4th or 5th when there is a light load on the engine, or when I am at highway speeds. What do I need to do to make the shift up light function as it should? As I mentioned before, the car is an original manual car, although the instrument panel was replaced by the previous owner due to an inop speedometer, which I suspect was taken from an automatic car. Thanks in advance!

 

The bulb was probably out for a reason, THAT reason. No problem, I don't think you need a light on the dash to tell you when to shift anyway. Just pull the bulb back out and go back to the way it was.

I didn't realize any third gens even had up-shift lights. Last one I remember seeing was in an '85 Sunbird. Does it not have a tach?

 

My 89 5 speed has one too..... it's for fuel economy I think was the idea behind it. While I just ignore mine... if it didn't work, I don't think I'd fix it.

Actually I was thinking it would be cool if the worked for high rpms...at red or yellow line.

 

Yeah, I have a tach. I can shift on engine sound alone due to years of driving old honda atvs, but my buddy I occasionally let drive my car thinks my car has a 4 banger and shifts as such, (like cruising at 3k rpm in 4th gear).
Does it show you when to shift for best fuel economy? I was hoping it showed the best powerband.
