4T40E 2001-2002 Chevrolet Cavalier & Pontiac Sunfire 2.2L FWD – Remanufactured 4-Speed Automatic Trans

Description

Engineered for compact commuter efficiency, the Chevrolet Cavalier 2001-2002 Remanufactured Transmission provides dependable transaxle performance for FWD passenger chassis. This transverse 4-Speed automatic manages 140 continuous horsepower alongside 160 lb-ft peak torque below a 5,600 RPM redline ceiling. Calibrated mainline pressure commands 180 PSI under wide throttle, preventing friction plate slip during rapid highway entrance ramp acceleration.

The rigid cast aluminum transaxle casing houses precision-cut helical gears, heat-treated planetary carrier sets, and premium cellulose-graphite friction discs. An updated hydraulic valve body includes hard-anodized valve bore sleeves to stop line pressure decay. Transaxle cooler ports connect to 5/16-inch quick-disconnect cooling lines. Total dry weight measures 155 lbs, holding 8.5 quarts of Dexron fluid alongside a factory-calibrated 245mm torque converter.

Key Features of Chevrolet Cavalier

Automotive repair facilities choose to buy Chevrolet Cavalier 2001-2002 remanufactured transmission packages to support economical customer transportation and fleet commuter sedans. This front-wheel transaxle platform restores precise gear shift intervals and smooth mechanical operation across challenging urban stop-and-go road traffic.

• 2.96:1 ratio 1st gear delivers responsive acceleration from street stops.
• 0.68:1 ratio 4th gear overdrive minimizes highway engine RPM to preserve fuel economy.
• 2001 Cavalier replacement valve body eliminates shift shudder through upgraded pressure regulator valves.
• Cavalier 2002 torque converter package uses balance-tested turbine fins for quiet lockup.
• Precision helical gear train module minimizes gear whine across highway cruising speeds.
• Reinforced direct clutch packs withstand repeated city stop-and-go friction engagement.
• Viton lip seals maintain internal hydraulic pressure across extreme winter and summer climates.
• Full-flow internal fluid filters trap abrasive particles before reaching sensitive shift solenoids.

Dynamic Transaxle Torque Boundaries

Mainline hydraulic circuits maintain 160 to 190 PSI during heavy acceleration to clamp clutch friction faces tight. Sump fluid temperatures operate between 165°F and 195°F inside operational radiator heat exchanger loops. The transverse transaxle handles 160 lb-ft input torque at 3,600 RPM from a 2.96:1 1st gear to a 0.68:1 overdrive. Continuous fluid circulation prevents thermal degradation across internal friction components.

Differential Axle Output Tolerances

Machined with 34-spline internal differential side gears, the transaxle housing accepts standard FWD half-shaft CV axles. The pilot register aligns engine block dowel pins within factory center limits. Dial indicator inspection holds differential carrier bearing runout below 0.0018 inches, preventing drive axle seal weeping and stopping chassis floorboard vibration under sustained highway cruising speeds.

Automated Transaxle Dynamometer Protocol

Technicians validate each transaxle on computerized dynamometers using heated test fluid under simulated passenger vehicle drag profiles. Equipment verifies shift solenoid response timing, line pressure stability, and converter lockup clutch holding torque. This transaxle is not engineered for bracket drag strip racing, off-road rallying, or vehicles operating with contaminated radiator oil cooler passages.

• Inspect automatic transaxle fluid level and condition every 14 operating days.
• Renew external auxiliary fluid filter units every 25,000 miles.
• Drain transaxle fluid and replace bottom pan filters every 12 months.

Verified Logistics Warranty Manifest

Protected by a comprehensive 3-Year unlimited mileage warranty, this remanufactured transaxle provides long-term operational peace of mind. The secure wooden transport crate contains a complete remanufactured transaxle, spin-balanced lockup torque converter, inline fluid filter, step-by-step transaxle installation manual, and certified fluid specification tags.
