There are two...one that sends a signal to the gauge and one that sends a signal to the computer.
The United States production number for the 1988 Pontiac Trans Am GTA was 9,765 units. The production number for Canada was 1,261.
The coolant temperature sending units are near the thermostat housing. The small one is for your temperature guage, the larger one is for the EEC system.
Temp sending units in general (not always) are usually found close to the thermostat.
Didn't mention the year or engine size but temp sending units are generally found close to the thermostat.
There are several sending units in that vehicle such as the fuel sending unit, the oil pressure sending unit, the temperature sending unit. Need to know which one you want to change.
It has several sending units such as a fuel gauge sending unit, oil pressure gauge sending unit, temperature gauge sending unit, need to know which one you are looking for.
They weren't selling enough of them to be profitable, anymore if GM can't sell 100,000 units a year of a certain vehicle they will quit making it.
my 1995 Explorer , with the 4.0 L OHV engine has 2 temperature sending units. They are located on the intake manifold by the thermostat housing (where top radiator hose connects to engine) Looking from the front of the vehicle, the temperature sending unit on the left is for the temperature guage in your instrument cluster and the larger temperature sending unit on the right is for the EEC system.
In 2002, a total of 2,340 units of the Pontiac Trans Am with a standard transmission were produced. This model year was part of the final production run of the Trans Am before it was discontinued.

The 1979 General Motors F-Body vehicles have live rear (Salisbury type) axles. These rear axles are 7.5 inch 10-bolt units.
The temperature gauge works intermittently or the temperature displayed varies varies or the gauge doesn't work at all. Many modern sending units serve two purposes, gauge and ECU. when the ECU side fails it should (but not always) throw up a fault code.
