4T80E 1994-1999 Cadillac DeVille, 1994-1997 Eldorado 4.6L FWD – Remanufactured 4-Speed Automatic Trans

Description

Full-size luxury sedan transport calls for this Cadillac DeVille 1994 Remanufactured Transmission developed for high-mileage Northstar vehicle chassis. The 4-Speed FWD driveline supports 275 continuous horsepower, 300 lb-ft input torque, a 6000 engine RPM limit, and 205 PSI hydraulic pressure. Heavy friction linings inside clutch packs resist heat build-up under full executive passenger payloads.

High-pressure die-cast aluminum creates a rigid transaxle housing with integrated fluid channels. Internal gearing utilizes carburized 8620 steel planetaries running alongside twin hardened drive chains. The valve body receives hard-anodized sleeves and a recalibrated pressure regulator valve to stop clutch slippage. Cooling fittings accept 3/8-inch lines. Dry weight equals 295 lbs, holding 15.0 quarts of fresh fluid alongside a balance-tested remanufactured torque converter.

Key Features of Cadillac DeVille

Chauffeur fleets buy Cadillac DeVille 1994 remanufactured transmission stock to preserve corporate transport passenger schedules. Clean hydraulic flow guarantees confident gear engagement through stop-and-go commercial city traffic.

• 4-Speed front-drive transaxle supports substantial curb weights and interior cargo loads
• High-capacity steel planetary gearsets balance load distribution across planetary pins
• Recalibrated valve body maintains constant line pressure during low engine speeds
• Segmented graphite friction discs eliminate clutch shudder across gear transitions
• 1994 DeVille replacement valve body eliminates shift solenoid sticking inside valve bores
• DeVille 1994 torque converter package stabilizes stall speeds under heavy vehicle loads
• Twin precision drive chains connect the transaxle input shaft to primary gearing
• Dual-lip rubber axle boots retain differential fluid while sealing against splash water

Sedan Hydraulic Ratio Dispersion

Internal line circuits supply 190 to 225 PSI of regulated mainline fluid pressure under full throttle uphill conditions. Auxiliary transmission cooler circuits keep sump oil operating within 165°F to 190°F limits. Peak input torque reaches 300 lb-ft at 4000 RPM. Gear reduction ratios span 2.96:1 in 1st gear, 1.63:1 in 2nd gear, 1.00:1 in 3rd gear, and 0.68:1 in 4th gear overdrive. Pressurized oil channels flood internal needle bearings continuously.

Differential Shaft Alignment Profiles

Internal differential splines engage factory 34-spline passenger axles and 32-spline driver axles. The perimeter bell housing bolt ring aligns to 4.6L engine blocks with runout measurements under 0.0018 inches. Structural transaxle mounting bosses mate to factory rubber mounts without chassis modifications. Output drive seals seat true inside precision-bored aluminum differential openings.

Load Cell Dynamometer Standards

Hot-fluid dynamometer runs subject each transaxle to heavy resistance cycles while measuring solenoid electrical resistance and hydraulic clutch clamping force. Fluid circuits undergo automated flushing before final crating. This transaxle is not engineered for utility trailer towing exceeding factory gross limits, snow-plow operations, or use without verified clean cooler circuits.

• Verify fluid levels using the transaxle dipstick every 14 operating days
• Perform complete transmission fluid and filter service every 30,000 miles
• Inspect transaxle subframe mounts for play every 12 months
