Is the "shift buzzer" affected by temperature? Just wondering because my 89 GTUs buzzer is very inconsistant as to when it goes off.

When temps are hot out, it will start buzzing around 7200 RPM. When it's cool out (Below 70 degrees) it won't sound till 8000 RPM.

Just curious... Thanks.

 

i took my dash out because my buzzer was hung up and it would constantly go off.i tapped it and put tha dash back in. its fine now. maybe your's is messed up??? not sure tho.

 

this is mostly first gens but those buzzers never work right. i had one that would just go off almost randomly, sometimes 4000, sometimes never, some times 6k it just buzzed whenever it felt like it.

 

shouldn't be, but could be.

 

My buzzer seems to do the same thing, it hasn't in awhile but there were times when it'd buzz lower. No idea why, i just tend to ignore it.

 

same happens to me in my 88 TII i always thought it was cause my coolant or oil was low...top them both off and see if it goes away. but that has never worked for me...its very random 5.5k-7k

There doesn't appear to be anything wrong with the buzzer. It only goes off when it is supposed too, but recently I noticed that as the temperature gets warmer outside, the buzzer sounds earlier.

For example: I was driving the car in 75-80 degree weather. The buzzer was constantly sounding at 7500 RPM. It started to rain and the outside temperature dropped to about 70 degrees. Once it started raining, the shift buzzer started going off at 7900-8000 RPM.

 

Maybe the buzzer is working but the tach is low when it's hot?

 

thats more likely to me

 

Humm, interesting theory!

I'll have to pay attention to the speedo the next time the buzzer goes off.

 

There are solder joints on the back of the tach, take a look and if you have some soldering skills you can remove the old solder and flow new solder into it.

My buzzer was not going off for a while. After doing this it started working like new.
