Also known as: l110, l210, lexus hybrid transaxle, rear-drive e-cvt, l110 hybrid transaxle
Toyota's rear-drive hybrid transaxle — the gearbox of the GS 450h, the GS 300h, the IS 300h and the RC 300h, built by Aisin.
⚑ It is the same idea as the Prius e-CVT and not the same gearbox. Both are power-split devices with two motor-generators and no clutch pack; this one sits in line with the car and drives the rear wheels, where the P-series transaxles sit across the engine bay and drive the front. A part, a fluid or a fault reported for a Toyota e-CVT may be about either.
The L110 carries a two-speed Ravigneaux gearset on its output, which the transverse units do not — it is what lets the GS 450h use a small motor at low speed and still pull at motorway pace. The L210 in the IS 300h and RC 300h is the same architecture without it.
There is no torque converter, no clutch and no set of ratios to wear, so the failures owners meet are electrical rather than mechanical: the inverter, its coolant pump, and the resolvers on the motor-generators. A shudder or a slip on one of these is not a gearbox symptom at all.
It takes Toyota's WS fluid and it is not a lifetime fill in practice. The transaxle shares its case with the motor-generators, so debris and heat reach windings rather than only clutches, and a drain and fill at sensible intervals is cheap against what it protects.

4 generations. Only where a source names the model and the generation together — a gearbox is documented as a product far more often than as a fitment, so this list is deliberately shorter than the truth.
Information, not instruction
CarGeek is a reference, not a service manual. Its pages are written from public sources and from what other people have found, never from a manufacturer's own service information, so they can be wrong or incomplete for your particular vehicle. Some of what they describe carries real risk: high voltage, fuel under pressure, stored energy, hot and moving parts.
Have anything you intend to act on checked by a trained person against the manufacturer's own procedure for your vehicle. Nothing here replaces that procedure.

What makes one worth reading:
- The car — make, model, year and engine. The same fault behaves differently on each.
- What you measured, not only what you replaced.
- What actually fixed it — or that nothing did, which is worth knowing too.
