Buick Riviera 1995 Automatic Transmission 4-Speed 4T60E Remanufactured

Description

Slot this remanufactured 1995 Buick Riviera transaxle 10542T into your front-wheel-drive bay for restored supercharged acceleration. Calibrated for 1995 Buick Riviera models with supercharged 3800 V6 engines, this four-speed automatic delivers crisp gear transitions across all speeds. You must verify vacuum modulator line integrity and flush cooler circuits prior to putting this unit into service.

Shot-peened A380 die-cast aluminum forms the heavy-duty transaxle casing, inspected for stress cracks around differential mounting bosses with dye penetrant. Hardened planetary pinions handle forced-induction 3.8L engine torque without tooth deflection. Rebuilders install updated boost valve sleeves, calibrated vacuum modulators, Kolene steel plates, and high-energy BorgWarner friction packs. Precision drive sprocket bearings eliminate chain whip. The dry unit weighs 195 lbs and ships inside a 36 by 24 by 22 inch crate.

Key Features of Buick 4T60E

Independent repair facilities buy Buick 4T60E transmission assemblies to correct delayed drive engagement without facing steep dealership part pricing. This commercial remanufactured transmission assembly provides dependable power transfer for your Buick Riviera supercharged transmission replacement project.

• Updated pressure boost valve assembly restores main line pressure balance across all throttle inputs.
• Calibrated vacuum modulator delivers accurate shift timing based on real-time engine vacuum load.
• Reamed valve body bores hold 22 inHg during calibrated vacuum test bench checks.
• Balanced remanufactured torque converter eliminates driveline vibration and protects front pump drive gears.
• BorgWarner high-energy friction clutch plates resist thermal glaze under prolonged highway driving cycles.
• Hardened intermediate band provides positive mechanical grip to eliminate second gear shift slip.
• Precision drive chain sprockets prevent link bind and preserve smooth power delivery.

SuperFlow Dynamometer Diagnostic Telemetry Data

Technicians subject every remanufactured 4T60E transaxle to hot and cold testing cycles on a SuperFlow transmission dyno. Pressure gauges verify main hydraulic line pressures holding 165 PSI in Drive and 225 PSI in Reverse at 1500 RPM. Mechanical modulator shifts actuate crisp gear transitions across manifold vacuum steps from zero to eighteen inches. Valve body circuits hold 20 inHg vacuum on precision bench gauges. The test program validates zero torque converter clutch slip at cruising speed. Thermal imaging cameras confirm leak-free front pump and drive axle seals under load.

Field Installation Directives Negative Filter

Spin the torque converter inward through three positive gear drops until the converter clears the front bellhousing face. Check engine block dowels for corrosion before bolting the bellhousing flat. Do not buy this factory calibrated unit for supercharged builds, manual swaps, or track race chassis.

• Flush cooler lines with hot chemical solvent to clear burned friction clutch sediment.
• Fill with approved Dexron fluid through the fill port at operating temperature.
• Adjust throttle valve cable geometry to factory specifications prior to highway road testing.

Nationwide Warranty Freight Crate Contents

Your purchase brings a nationwide 3-Year/100,000-Mile warranty protecting against internal mechanical damage and hydraulic pressure control faults. The sturdy wooden freight crate houses a balanced torque converter, technician installation guide, dynamometer inspection pass slip, cooler flush checklist, and a pre-printed core return bill of lading for simple return transit.
