What is the 4th gear pressure switch on TH200-4R?
This ended up being the 4th Gear Pressure Switch that the CZ model (for the Monte Carlo SS) of the TH200-4R uses to tell the ECM when the transmission reaches 4th gear. That lead ended up (logically) to be the wrong path.
Where is the 4th gear pressure sensor switch?
Skip the first two steps if you do not have a 4th gear pressure sensor switch in the earlier models. The 4th gear pressure switch is accessed from above, while the third gear is accessed from below. The 4th is more involved to get to, and we’ll start by removing the engine cover which should pop right off rather easily.
What is the new transmission pressure switch number?
4th switch or 28600-RAY-003 = 28600-RAY-013, which has now been replaced by 28600-RKE-004. Can somebody please verify that the new part numbers are correct cross references to the old originals?
Why does my Chevy transmission not go into 3rd gear?
Chevy transmission won’t shift, stuck in 1st gear or limp mode – Speedometer may also display zero at all times. It could be internal transmission failure, low transmission fluid, or faulty Vehicle Speed Sensor (VSS sensor). Chevy transmission won’t go into 3rd or 4th gear – This is a good indication that 3 or 4 gear clutches are worn.

Where is the 4th gear pressure switch located?
The 4th gear pressure switch is accessed from above, while the third gear is accessed from below. The 4th is more involved to get to, and we’ll start by removing the engine cover which should pop right off rather easily. You may want to unbolt the air cleaner housing first to give you some extra room, but it isn’t required.
