Thee Powertrain: 4.0L Engine Mastery
Thee 4.0L inline- six (AMC / Jeep 242) is the gold standard of XJ reliability. It 's not faset faset modern standards - about 190 horipower and 225 lb- ft of torque - but it delivers torque low in thee rev range, making ideal for crawling and daily driving. The engine' s iron block and cylinder head are overbuilt. With routine oil changes, the valvetrain, bottom end, and colooling stem caesily ned 250,000r.

With proper consumance, the 4.0L will outlass thee reste of thee vehicle. Many owners report oil analysis showing minimal wear metals at 150k mils.
Transmissionon Choices: Which Holds Up?
Two main transmissions were offered: thee Aisin- Warner AW4 four-speed automatic (thee most compatin) and the Aisin AX- 15 (1991- 2000) or NV3550 (2000- 2001) manual.
AW4 Automatic
Te AW4 is a torque converter automatic designed by by Aisin. It 's essentially thee same transmissionon found in some Volvo and Toyota models. It shifts smoothly and can handle difficient torque. However, it does have sleak points:

| Cooling system overhaul (radiator, hoses, pump, thermostat) | $250 | $800 | Once |
| Transmission service (fluid + filter) | $60 | $200 | 2–3 times |
| Front end rebuild (ball joints, tie rods, track bar) | $350 | $1,200 | 1–2 times |
| Brake pads and rotors (all four corners) | $200 | $600 | 2–3 times |
