Product Details
Womala Auto Transmission Input Speed Sensor OE 1850527 Transmission
Sensor for Volvo XC60
The Transmission Input Speed Sensor (Transmission Sensor, OE
Number: 1850527) is a key electronic component for monitoring
transmission operation, exclusively designed for Volvo XC60 models
produced between 2015–2025. As an OE-grade part, it is installed on
the transmission case, near the input shaft (connected to the
engine). Its core role is to real-time detect the rotational speed
of the transmission input shaft, transmitting speed data to the
vehicle’s TCM (Transmission Control Module)—this data is critical
for the TCM to adjust shift timing, clutch engagement, and torque
distribution, ensuring smooth transmission operation.
Crafted from high-reliability materials—including a heat-resistant
plastic housing (to withstand high temperatures inside the
transmission case) and a precision inductive or Hall-effect sensing
element (for accurate speed signal output)—this sensor operates
stably in harsh transmission environments: high heat, vibration,
and exposure to transmission fluid. It strictly adheres to Volvo’s
electrical and dimensional standards, ensuring consistent signal
transmission (without interference) and a tight seal with the
transmission case (to prevent fluid leakage).
Core Functions
- Input Shaft Speed Detection: Continuously monitors the rotational
speed of the transmission input shaft, converting mechanical
rotation into electrical signals and transmitting them to the TCM.
This data helps the TCM calculate the speed ratio between the
engine and transmission.
- Shift Timing Optimization: Enables the TCM to adjust shift timing
(e.g., upshifting or downshifting) based on real-time input shaft
speed and engine load. This ensures smooth, timely shifts, reducing
transmission shock and improving driving comfort.
- Transmission Protection: Works with the TCM to detect abnormal
speed differences (e.g., input shaft speed mismatch with engine
speed) which may indicate issues like clutch slippage. The TCM can
then trigger protective measures (e.g., limiting torque) to prevent
transmission damage.
Compatible Vehicles
This Transmission Input Speed Sensor (OE: 1850527) is tailored for
Volvo XC60 models within the specified production years:
| Model | Applicable Year Range |
|---|
| Volvo XC60 | 2015–2025 |
Notes: Transmission sensors may vary by transmission type (e.g.,
automatic vs. semi-automatic) even within the same model year
range. For 100% fitment accuracy—confirm compatibility with your
XC60’s specific transmission configuration—verify with your
vehicle’s VIN (Vehicle Identification Number) or consult Volvo’s
official service manual. This avoids mismatches caused by subtle
differences in sensor mounting or signal protocols.
Frequently Asked Questions
Q: How to determine if the bumper bracket needs replacement?
A: Signs of a failing bumper bracket include visible damage or
deformation, misaligned bumper panels, unusual noises from the
front end, or if the bumper appears loose or sagging on one side.
Q: What should be paid attention to when replacing the bumper
bracket?
A: For optimal results, we recommend professional installation. Key
considerations include ensuring proper alignment of all mounting
points, checking for additional damaged components, and verifying
all fasteners are properly torqued to specification.
