Can a 1998 jeep wrangler with standart 5 speed 4x4 transmission be converte to automatic transmission?

Converting a 1998 Jeep Wrangler with a standard 5-speed 4x4 transmission to an automatic is possible, but it's a significant undertaking, far beyond a simple swap. It's not a bolt-in job. You'll need more than just the transmission itself.

Here's what's involved:

* Transmission: You'll need a compatible automatic transmission, likely from a later model Jeep Wrangler or possibly another vehicle that shares a compatible transfer case and bellhousing. The transmission must be suitable for the engine's torque and power output.

* Transfer Case: The transfer case might need to be changed or adapted depending on the donor automatic transmission. Automatic transmissions often have different output shafts than manuals.

* Computer/Electronics: The automatic transmission will require a compatible computer module (PCM) and potentially wiring harness modifications. The 1998 Wrangler's system is likely not set up for an automatic transmission. This is a complex area that requires significant electrical knowledge.

* Driveshaft: The driveshaft length may need to be adjusted depending on the transmission and transfer case combinations used.

* Torque Converter: An automatic transmission uses a torque converter, which needs to be included in the conversion.

* Pedal Assembly: The clutch pedal and associated linkage will need to be removed, and potentially the brake pedal will need adjustment.

* Shift Linkage: You'll need the appropriate shift linkage for the automatic transmission.

* Wiring Harness: The original wiring harness may need significant modifications or even replacement with a harness designed for an automatic transmission.

* Calibration: After the swap, the vehicle's computer will need to be programmed or calibrated to work with the new automatic transmission. This is usually done with a professional-grade scan tool.

In short: While technically feasible, this conversion is a major mechanical and electrical project best left to experienced mechanics. The cost of parts and labor could easily exceed the value of the Jeep, especially considering the specialized skills required. It's far more labor-intensive and expensive than many other car modifications. Unless you have considerable mechanical and electrical expertise, it's strongly recommended to avoid this conversion.
