Remanufactured TR580 CVT Transmission Valve Body 31825AA050 31825AA051 31825AA052 31825AA053 For Subaru Forester Impreza XV Crosstrek Outback Levorg Exiga

• Product Overview

This remanufactured TR580 Lineartronic CVT valve body is the core hydraulic control assembly for Subaru TR580 CVT transmission. Every unit is fully disassembled, cleaned, inspected, worn spools, sleeves, solenoids and sealing components are replaced with upgraded OE-spec parts. It controls hydraulic pressure, clutch engagement and shifting logic to fix common failure codes P2757 P2762 P2764, and resolve issues like shudder, slipping, delayed engagement, no forward or reverse gear. It is targeted at overseas transmission rebuild shops, auto repair chains and wholesale distributors, ready for direct installation after bench testing.

• Inspection & Testing Standard 

We adopt strict remanufacturing inspection flow for each TR580 valve body. First, complete teardown and ultrasonic cleaning for all casting passages and components to remove old ATF sludge and metal debris. We measure spool valve clearance, check bore wear and solenoid resistance. All replaced solenoids are tested for pressure response and current curve. After reassembly, every finished valve body goes through dynamic hydraulic bench test under simulated working pressure, to verify line pressure, clutch pressure, solenoid actuation and shift sequence. Only units passing all test records can be packed for shipment. Each unit has unique test report and batch traceability code.

• Core Competitive Advantages

Full remanufacture instead of simple cleaning, all vulnerable solenoids and sealing parts renewed with upgraded material. Dynamic hydraulic bench test for every single piece, not just static visual inspection, greatly reduce on-car failure rate. Covers 4 common interchange OE numbers, supports wide Subaru TR580 CVT models, helps reduce your SKU inventory pressure. Strict OE hydraulic calibration, consistent pressure curve same as original, no need extra modification after installation. Factory direct wholesale price, stable stock support, fast lead time for urgent repair orders. Free VIN matching service to confirm start-stop / non start-stop version difference before shipment. Private label neutral packing is available for B-end wholesale partners.

• Professional Installation

Guidance Before installation, confirm the valve body version matches the original unit, distinguish start-stop and non-start-stop variant, these two versions are not interchangeable. Fully drain old CVT fluid, replace transmission filter and gaskets together, flush the oil cooler completely to eliminate metal contamination. Check wiring harness connector for corrosion and pin damage before plugging in. After installation, fill with Subaru CVT Lineartronic fluid, clear DTC codes and complete CVT adaptive learning procedure. Road test under light load first, check for shudder, pressure fluctuation and abnormal codes. If pressure fault still appears, double-check oil cooler and internal transmission mechanical damage. Our technical team provides remote support for abnormal cases.

• Packaging & Transportation

Each remanufactured TR580 valve body is wrapped with anti-rust film and shockproof foam inside a custom export carton. The carton is marked with part number, transmission model, gross weight and batch number. We add desiccant inside the package to avoid moisture corrosion during long sea transit. We support sea freight, air freight and international express. Custom shipping marks can be printed on outer cartons for bulk orders. We can provide commercial invoice, packing list, test report and certificate of origin for your customs clearance.

• FAQ

Q1: How do you distinguish the start-stop version from non-start-stop version of TR580 valve body by internal structure, and why they cannot be interchanged directly?

A: The start-stop TR580 valve body has extra solenoid circuits and modified hydraulic control passages specially designed for frequent engine restart logic. Its solenoid current parameters and pressure response curves are calibrated to maintain stable CVT hydraulic pressure when the engine shuts down temporarily. The non-start-stop version lacks these adjusted hydraulic circuits and corresponding solenoid control settings. If you install the wrong version on the vehicle, you will encounter fault codes, unstable line pressure, sudden shudder, or even failure of the auto start-stop function. Even if the external appearance and OE part numbers look similar, the internal calibration is different. We will cross-check your VIN code and original part number carefully before shipment to confirm the correct variant, so you can avoid costly return and rework caused by mismatched versions for your repair shop customers.

Q2: What is your rejection standard for the core raw casting bodies when you source used TR580 valve bodies for remanufacturing?

A: We have strict screening rules for every used TR580 valve body casting before remanufacturing starts. Any casting with deep scoring, crack, porosity, deformed mounting surface, or severely worn valve bore beyond our acceptable clearance limit will be scrapped directly and will not enter our production line. Even if the surface looks fine, we will measure every valve bore precisely. If the bore wear exceeds the tolerance that can be fixed by lapping, we discard this core. We only keep intact, low-wear casting blanks to proceed with ultrasonic cleaning, lapping, solenoid replacement and assembly. This strict core selection is the foundation of stable hydraulic performance, and it helps us keep the on-car failure rate low for your wholesale orders.

Q3: After we receive the TR580 remanufactured valve body, what simple self-inspection steps can our repair shops perform without a professional hydraulic test bench?

A: Although full hydraulic dynamic testing requires a dedicated bench, your downstream repair shops can run several basic checks after receiving the goods. First, visually inspect the casting for cracks, impact damage and loose solenoid connectors. Second, use a multimeter to measure the resistance of each solenoid, compare the reading against our supplied standard resistance range to confirm solenoid continuity. Third, check all sealing rings and gaskets to confirm no deformation or aging during transit. Fourth, blow through the oil passages gently with low-pressure clean air to verify there is no residual debris blocking internal channels. These steps cannot replace full hydraulic testing, but they help catch obvious shipping damage or defective units before installation. If any abnormality is found, you can contact us immediately with photos and test data for support.
