4T80E 2000-2002 Cadillac DeVille 4.6L FWD – Remanufactured 4-Speed Automatic Trans

Description

Extended luxury sedan operation defines this Cadillac DeVille 2000 Remanufactured Transmission suited for high-demand municipal and private transportation. Operating across a 4-Speed FWD footprint, this unit sustains 275 continuous horsepower, 300 lb-ft input torque, a 6000 engine RPM limit, and 205 PSI hydraulic pressure. High-energy friction plates maintain firm gear changes through demanding city transit.

Cast A380 aluminum forms the outer transaxle shell. Internal mechanics utilize 8620 carburized planetary steel gears, hardened reaction sun shells, and hard-anodized valve body bore sleeves that prevent hydraulic pressure leakage. Transmission cooler lines mate to 3/8-inch ports. Total dry weight measures 295 lbs, requiring 15.0 quarts of recommended fluid alongside an electronically balanced remanufactured torque converter.

Key Features of Cadillac DeVille

Automotive repair professionals buy Cadillac DeVille 2000 remanufactured transmission units to restore factory shift performance in full-size luxury sedans. Updated hydraulic valves ensure positive line pressure during high-demand road passes.

• 4-Speed front wheel drive configuration provides balanced gear splits for highway cruising
• Carburized 8620 alloy planetary gearsets resist wear during wide-open throttle passing
• Hard-anodized valve body bore sleeves eliminate hydraulic pressure dropouts
• Segmented friction clutch plates resist glazing during high-temperature summer runs
• 2000 DeVille replacement valve body provides crisp gear shifts without harshness
• DeVille 2000 torque converter package delivers direct lockup without clutch slip
• High-strength twin drive chains link the input shaft to main planetary components
• Dual-lip axle shaft seals prevent transaxle fluid loss at differential outputs

Hydraulic Control Gear Ratios

The transmission pump generates line pressure between 190 and 225 PSI under heavy throttle inputs to clamp clutches securely. Fluid cooling circuits keep sump oil between 165°F and 190°F during long highway trips. Peak continuous input torque manages 300 lb-ft at 4000 RPM. Gear reduction ratios feature 2.96:1 for 1st gear, 1.63:1 for 2nd gear, 1.00:1 for 3rd gear, plus 0.68:1 in 4th gear overdrive. Dedicated fluid paths lubricate internal thrust bearings.

Driveline Axle Interface Standards

The differential unit accommodates factory 34-spline passenger-side axles and 32-spline driver-side CV joints. Engine bell housing dowel points keep case alignment runout within 0.0017 inches to prevent pump bushing failure. Transaxle mounting points bolt directly to stock chassis engine cradles. Differential output bushings hold precise tolerances to stop driveline vibration under hard acceleration.

Dyno Testing Application Exclusions

Automated dynamometer load testing verifies solenoid resistance, hydraulic circuit pressure, and smooth shift actuation under full operational temperature before shipping. Fluid passages receive pressure flushing to remove particles. This transaxle is not engineered for supercharged drag racing, track day autocross abuse, or installations paired with contaminated factory radiators.

• Check fluid level using the indicator stick every 30 operating days
• Change transaxle fluid and replace the pan filter every 30,000 miles
• Inspect transmission cooler lines and fittings every 12 months

Warranty Assurance Crate Items

Purchases include a 3-Year unlimited mileage warranty covering commercial and personal vehicle applications. Every shipping crate includes the complete remanufactured transmission, dynamic balanced torque converter, replacement cooler clips, and installation instructions. Durable wooden crates protect external casing tabs from transit damage during freight transport.
