The JATCO CVT Transmission is a continuous variable transmission with a pair of variable pulleys, a steel belt and a shifting ratio planetary gear set designed to improve the overall performance of the transmission.
Each pulley set has one fixed sheave and one moving sheave which determine the transmission ratio in each range.
This transmission has an overall ratio spread of 7.3:1
Transmission Fluid Level and Condition Check
1. The vehicle must be on a flat surface.
2. Move the selector lever into the Park (P) position and then completely engage the parking brake.
3. Start and idle the engine.
Notice: The CVT fluid is largely affected by temperature, therefore be sure to use the diagnostic tool to check the fluid temperature while adjusting.
4. Wait until the transmission fluid temperature reaches 122°F (50°C).
5. Move through the selector lever positions with the foot brake depressed. Switch the selector lever from position P to L and then back to P. Hold each position for at least 5 seconds.
6. Verify that there are not any transmission fluid leaks.
Notice: Continue to perform this work with the engine idling.
7. Check the transmission fluid temperature with the diagnostic tool.
8. When the transmission fluid temperature has reached approximately 122–176°F (50–80°C), raise the vehicle.
9. Remove the drain plug (1). Remove and DISCARD the drain plug gasket (2).
⇒ If the fluid is flowing as a steady stream, wait until the fluid begins to drip. If no fluid comes out, add fluid until it drips out.
Notice: Do not re-use drain plug gasket, replace with a NEW gasket.
10. When the fluid drips out from the overflow tube, install the drain plug (1) with a NEW gasket (2) and tighten to 34 Y (25 lb ft).
11. Lower the vehicle.

Hi I have a question more than a comment, I have a 2014 chevy spark 1LT and I am receiving a p0871 code that is saying transmission fluid pressure sensor. I have searched for days and weeks now and I can not find any information on the part or how to resolve my issue. Can you please help me with any information on what I should do?
DTC P0871 : Transmission Fluid Pressure Switch 3 System Performance
Circuit/System Description
The Transmission Fluid Pressure Switch 3 also known as the Oil Pressure Switch is part of the control solenoid valve assembly which has no serviceable parts.
The Transmission Fluid Pressure Switch 3 shares the Transmission Manual/Automatic Date Output circuit with the ROM Assembly in the transmission. The ROM Assembly uses the Transmission Manual/Automatic Date Output circuit as a low speed serial data circuit between the ROM Assembly in the transmission and the transmission control module. The ROM Assembly only communicates with the transmission control module when the RUN/CRANK circuit goes high. Data is transmitted once during the drive cycle and happens quickly. After that data exchange, the function of the Transmission Manual/Automatic Date Output circuit becomes the Transmission Fluid Pressure Switch 3. The Transmission Fluid Pressure Switch 3 reflects the status of the high clutch oil pressure. The Transmission Fluid Pressure Switch 3 is normally open. When the clutch is commanded ON the Transmission Fluid Pressure Switch 3 closes. The DTC sets if there is a mismatch between the TCM commanded high clutch position and the status of the switch.

Diagnostic Aids
Caution: Use correct transmission fluid only. Failure to use the proper fluid may result in transmission internal damage.
A Transmission Fluid Pressure Switch may malfunction due to normal debris in the transmission fluid causing a Transmission Fluid Pressure Switch DTC to intermittently set. If DTC P0871 continues to intermittently set, replacing the transmission fluid may correct the problem. Refer to Transmission Fluid Level and Condition Check for transmission draining and filling.
Circuit/System Verification
Ignition ON. Engine OFF. Transmission in Park.
Verify that the Transmission Fluid Pressure Switch 3 scan tool parameter displays HIGH.
If the parameter does NOT display HIGH
Refer to Circuit/System Testing.
If the parameter does display HIGH
Using the S3 Transmission Shift Lever, shift the transmission to Low.
While monitoring the Transmission Fluid Pressure Switch 3 parameter, accelerate the vehicle to 60 km/h (37 mph). Maintain that speed for at least 15 s with the Calculated Throttle Position parameter displaying less than 20%.
Verify that the Transmission Fluid Pressure Switch 3 parameter continues to display High.
If the parameter does NOT display High
Refer to Circuit/System Testing.
If the parameter does display High
Stop the vehicle.
Using the S3 Transmission Shift Lever, shift the transmission to Drive.
While monitoring the Transmission Fluid Pressure Switch 3 parameter, accelerate the vehicle to 60 km/h (37 mph). Maintain that speed for at least 15 s with the Calculated Throttle Position parameter displaying less than 20%.
