About these transmissions

Every used transmission we quote for the 2004 Lexus LX is pulled from a donor vehicle with a logged VIN and documented history, then run through the same intake process regardless of which of the 1 transmission options you need: a thorough visual inspection of the case for cracks, a pan drop to evaluate fluid condition and check for excessive metal debris, and a rotational test of the input and output shafts.

Because inventory turns over regularly, exact mileage and price vary by the specific unit currently in stock - that's why we quote rather than list a single fixed price. Most in-stock 2004 Lexus LX transmissions fall between 60,000 and 110,000 miles, with inspection results included in every quote.

All 1 transmission options ship with a 12-month warranty and a refundable core charge, detailed further down this page.

Didn't know which transmission I had - selected "not sure" and they confirmed it was the 5.4L before quoting. Saved me a headache.
