Description

Toyota U151E U151F Automatic Transaxle Repair Manual RM1021U

This Toyota U151E U151F Automatic Transaxle Repair Manual RM1021U is a factory-style workshop manual built entirely around the removal, disassembly, inspection, reassembly and installation of the U151E and U151F automatic transaxle units. Every procedure in this Toyota U151E U151F manual follows the same disassembled-parts drawing format used by Toyota technicians, so a tightening torque, a non-reusable part, or an oil-applying point is never buried in a paragraph — it sits right next to the illustration it belongs to.

Taken together, this Toyota U151E U151F automatic transaxle repair manual gives a technician everything needed to work through a full transaxle overhaul from the outside in: removing the unit’s external hardware, splitting the case, pulling clutch packs and planetary gearsets, rebuilding the valve body, and putting it all back together to factory torque and clearance values.

Service Data You Can Actually Use

Rather than vague ranges, this manual prints exact standard and maximum values — oil pump body, tip and side clearances, drive and driven gear thickness by mark, and pack clearances for the forward clutch, reverse clutch, direct & O/D clutch, 2nd brake, U/D clutch, U/D brake, and 1st & reverse brake. Flange-thickness selection charts are included for each clutch pack so the correct shim can be picked during reassembly instead of guessed at. Accumulator spring free lengths, outer diameters and color codes (B3, C2, C3) are listed alongside front differential backlash, preload, and thrust-washer thickness marks for both the U151E and U151F differentials.

Torque Values for the Full Rebuild

A dedicated torque specification table lists Newton-meter, kgf·cm and ft·lbf values for every major fastener in the U151E/U151F transaxle — front planetary gear lock nut, transaxle housing bolts, oil pump assembly bolts, valve body bolts, shift solenoid bolts, oil pan and drain plug, speed sensor, oil cooler tube union and elbow, and the park/neutral start switch. These values are pulled directly into the disassembly and reassembly steps as well, so the correct torque is always visible at the point it’s needed.
