However, there are some important caveats:
* Finding a used transmission: Used transmissions are readily available for both types, but their condition is crucial. A thorough inspection or purchase from a reputable source is highly recommended.
* Bellhousing compatibility: While both transmissions are designed for the 4.0L, the bellhousing must match the transmission. You can't just swap a transmission and expect it to bolt up without the correct bellhousing.
* Transfer case compatibility: The transfer case must also be compatible with the chosen transmission. Usually, the transfer case will be compatible if the transmission is the original type for that Jeep. However, swapping to a different transfer case may require additional modifications or adapters.
* Other related parts: You might need other components such as the correct driveshafts, depending on the specific transmission and transfer case setup.
In short, while an AX-15 or AW-4 *should* fit, you must ensure compatibility across all related parts. It's always best to consult a Jeep mechanic or a parts specialist to confirm compatibility and to ensure a smooth installation.
