Taken together, this document walks a technician through the entire internal architecture of the U151E and U151F transaxle — from the oil pump and clutch packs through the planetary gearset, valve body, and front differential — with each stage broken into numbered removal, disassembly, inspection, reassembly, and installation steps.

What’s Inside

Every major internal assembly gets its own section in this U151E U151F automatic transaxle manual. The forward clutch, direct clutch, second brake piston, and underdrive clutch assemblies are each covered with numbered step-by-step procedures, SST tool call-outs (e.g., 09214-76011, 09223-15020, 09950-60020), and torque values presented in N·m, kgf·cm, and ft·lbf. The Underdrive Planetary Gear Assy and Transmission Valve Body Assy sections carry the same depth, including shift solenoid torque values (SL1, SL2, SL3, S4, DSL) and oil strainer/valve body fastener specs.

IMAGES PREVIEW

The Service Specifications chapter is a standout for anyone rebuilding this unit: it includes oil pump body, tip, and side clearance standards, and a full Torque Specification table listing well over 30 individual fasteners — from the front planetary gear lock nut (210–350 N·m) down to small case plugs (7.4 N·m) — everything needed to torque the transaxle back together correctly.

The Front Differential Assy is documented separately for the U151E and the U151F, since the two variants differ internally, including differential side bearing retainer oil seal installation and ring gear bolt torque (95.1 N·m) procedures.

Why This U151E U151F Repair Manual Matters

An automatic transaxle rebuild lives or dies on correct clearances and torque values — get a clutch pack clearance or a case bolt torque wrong and you’re pulling the unit back out. This RM1021U manual gives you the manufacturer-style numbered procedures, the exact SST part numbers Toyota specifies, and the full torque table so you’re not guessing or relying on generic aftermarket data. Whether you’re chasing a shift solenoid, rebuilding the underdrive clutch pack, or replacing a differential oil seal, every step here is traceable back to a documented spec.
