U341E 2008-2009 Scion xD 1.8L FWD – Remanufactured 4-Speed Automatic Trans

Description

Prevent intermediate clutch pack slippage under 128 lb-ft sustained output while maintaining 180°F fluid sump stability during demanding regional delivery operations using the Scion U341E Remanufactured Transmission built for 2008 to 2009 xD 1.8-liter front wheel drive commercial fleet hatchbacks.

A380 aluminum transaxle cases combine housing stiffness with rapid heat dissipation into underbody air streams. Hardened steel planetary gear sets pair with carbon-metallic friction discs featuring radial cooling grooves to withstand high-load highway acceleration. Hardware specs detail a furnace-brazed torque converter, 3/8-inch cooler fittings, 6.8-quart fluid sump capacity, and an overall dry unit weight of 138 lbs.

Key Features of Scion U341E

Commercial courier services buy Scion U341E remanufactured transmission units to restore work vehicle mobility and eliminate transmission slip on highway acceleration ramps. Every rebuilt transaxle features re-machined valve bodies to guarantee precise line pressure regulation under heavy cargo loads.

• Sonnax valve body bore sleeves halt hydraulic fluid bypass to preserve clutch clamp pressure
• Carbon-metallic friction plates resist heat buildup during long highway climbs
• Furnace-brazed torque converter impellers prevent vane flex under high stall loads
• Pulse-width modulated shift solenoids execute gear changes without driveline hesitation
• Scion U341E transaxle packages pass strict dial indicator runout and dyno load checks
• Nitrided planetary sun gear teeth prevent surface spalling under continuous vehicle operation
• Bottom-access steel fluid pans with magnetic drain plugs permit easy oil inspection

Planetary Torque Multiplication Pressure Levels

Engineered for commercial utility transport, this four-speed automatic transaxle channels 128 lb-ft continuous input torque at 4,400 RPM under 155 to 210 PSI main line hydraulic pressure. Sump temperature runs between 160°F and 185°F under full-load routes. Forward ratios feature 2.847:1 first, 1.552:1 second, 1.000:1 third, and 0.700:1 fourth overdrive, dissipating 36 BTU per minute through the cooling system.

Differential Side Gear Spline Dimensions

Rotational torque outputs through dual 23-spline differential side gears designed to seat factory front drive axles. Total dial indicator runout across output sockets holds under 0.0017 inches to stop driveline shudder. High-grade viton axle seals protect internal fluids from road water and grime.

Electro Hydraulic Transaxle Maintenance Protocols

Conduct transmission computer adaptation relearn procedures following installation to ensure optimal shift timing. This automatic transaxle is not engineered for heavy utility equipment hauling, off-road trials, or vehicle conversions exceeding manufacturer gross ratings.

• Check transmission dipstick fluid level and clarity each shift
• Flush transaxle fluid and replace pan filter every 30,000 miles
• Inspect engine and transmission rubber mounts every 12 months

Commercial Fleet Warranty Delivery Manifest

Covered by an outstanding 3-Year / 100,000-Mile commercial fleet warranty, this unit provides dependable long-term service. Shipment contains a fully remanufactured automatic transaxle, balanced torque converter, cooler flush kit, and a certified dyno test report.
