AB60E Banner Rebuild Kit

A 5.7L Tundra or Sequoia that flares between gears with a trailer behind it, sits in neutral for a second before Drive engages, or shows dark fluid with lining flakes on the pan magnet has worn clutch material in its six-speed AB60E (or AB60F on four-wheel-drive trucks). This banner rebuild kit pairs a complete overhaul gasket and seal set with a Raybestos RCP96-261 high-energy friction pack, which covers every clutch and brake friction in the unit for 2007-and-later AB60E and AB60F transmissions.

What the banner rebuild kit does in an AB60E

Aisin's internal name for the AB60E is TB-68LS, and Transmission Digest describes it as a scaled-up A761E built to carry V8 torque. It shifts six speeds with four rotating clutches (C1 to C4) and four holding brakes (B1 to B4). Raybestos lists exactly what is in this friction pack: 6 C1 forward plates, 5 C2 direct plates, 5 C3 reverse plates, 4 C4 coast plates, 4 B1 segmented plates, 4 B2 sixth-gear plates, 4 B3 second-gear plates and 7 B4 reverse brake plates, 39 frictions in all and high-energy lining throughout. The overhaul kit side brings the bonded rubber pan gasket, metal-clad seals, valve body gaskets, the sealing ring set and the O-rings for the pistons and passages. Together they renew the parts that wear and leak in a normal teardown. Steel plates are not part of this kit, so plan to reuse good steels or buy them separately.

Symptoms this kit addresses

• Flare or slip on upshifts, worst when towing or climbing with a hot transmission
• Slow engagement into Drive or Reverse after the truck sits
• Burnt-smelling fluid with friction material in the pan
• A slip that comes back after a fluid change, often with ratio or slip-related codes stored
• Seepage from the pan or at the axle and pump seals that a reseal alone would not cure if the clutches are also worn

How to confirm before you buy

An AB60 that runs dirty fluid can also show solenoid and valve body faults, and those mimic slipping clutches. Check fluid level at the correct temperature first, then read live data for commanded versus actual gear. Our Aisin slipping under load guide walks through that test, and Aisin harsh or delayed shifts covers the shift-quality complaints that point to the valve body instead. If the pan has heavy lining debris, the unit needs to come apart, and this kit is the right scope.

Fitment

The kit is listed for Toyota AB60E and AB60F transmissions from 2007 on, the six-speed used behind the 5.7L V8 in the Tundra and Sequoia. The same friction pack is catalogued for both two-wheel-drive and four-wheel-drive versions. Toyota also used the AB60 family in Land Cruiser 200 and Lexus LX570 models, so confirm the transmission ID tag on your unit reads AB60E or AB60F before ordering. If you are unsure, send your year and VIN and we will check it. Browse the rest of the Aisin transmission parts for this family.

Install notes

• Soak new frictions in Toyota WS ATF before assembly. WS is the only fluid these units should run.
• Inspect the steels. Heat-blued or warped steels should be replaced; the AB60E/AB60F master rebuild kit adds a full steel set if yours are cooked.
• The B1 brake uses segmented and solid frictions of slightly different thickness, so stack each pack in the order you removed it and check clearance on every clutch and brake.
• The forward drum and the bushings are known weak points in this family. Check drum splines and bushing wear before you close the case.
• The kit has no filter. Add the AB60E/AB60F filter kit so debris from the old clutches cannot reach the new ones.
• Flush the cooler and lines, and replace a sticking cooler thermostat. Heat is what burned the original clutches on most of these trucks.
• Clear adaptive values with a scan tool after the rebuild and drive gently through every shift while the TCM relearns.

Does this kit fit both the AB60E and AB60F?

Yes. The Raybestos RCP96-261 friction pack and the overhaul set are listed for AB60E (two-wheel drive) and AB60F (four-wheel drive) from 2007 on. Confirm the ID tag on your transmission, or send your year and VIN.

Are steel plates or a filter included?

No. The kit is the overhaul gasket and seal set plus 39 friction plates. Reuse steels that are flat and not heat-discolored, or buy a steel set, and add a new filter.

What fluid does the rebuilt AB60E need?

Toyota WS ATF only. Soak the new frictions in WS before assembly and set the level at operating temperature through the check plug, not by guessing.

Will this fix a shudder at highway speed?

Only if the shudder comes from worn clutches. Converter lockup shudder is common on AB60 trucks and needs converter service or a lockup solenoid check, so diagnose it before rebuilding.

Do I need to relearn the transmission after installing it?

Yes. Reset the adaptive values with a scan tool after the rebuild, then drive through all six gears gently so the TCM can learn the new clutch fill times.
