The 2000 Ford Explorer used a four-speed automatic transmission, typically the Ford 4R55E overdrive unit.
Across the 2000 Explorer lineup, two engines were available—the 4.0-liter V6 and, in certain trims, an optional 5.0-liter V8—but both configurations employed a four-speed automatic with overdrive. No manual transmission was offered in the U.S. market for this model year; the 4R55E electronic-overdrive automatic was designed to work with both engines and the two- and four-wheel-drive setups the Explorer offered.
Key characteristics of the transmission in the 2000 Explorer
The following points summarize the main attributes of the automatic transmission used in the 2000 Explorer.
- Four forward gears with an overdrive ratio for better highway fuel economy
- Electronic control via the Powertrain Control Module (the 'E' in 4R55E)
- Used with both two-wheel-drive and four-wheel-drive Explorer models
- Not offered with a manual transmission in U.S. market applications
In short, the 4R55E was the standard, widely used automatic transmission for the 2000 Explorer lineup, chosen for its balance of performance and efficiency across engine choices.
Maintenance and common issues to watch for
If you're maintaining or shopping for a used 2000 Explorer, these are practical considerations related to the transmission.
- Fluid type and level: Ford specifies Mercon V for the 4R55E; check and replace at intervals recommended by Ford or your owner's manual
- Common issues: hard shifts or delay in engagement can indicate solenoid or valve-body wear, fluid contamination, or overheating
- Leaks and seals: inspect pan gasket, input/output seals, and cooler lines for leaks
- Maintenance interval: routine servicing—fluid and filter change—helps extend life; a rough target is every 30,000–60,000 miles depending on driving and conditions
Proper care and timely service can protect the 4R55E's reliability in the 2000 Explorer, which continues to be a focus for many owners today.
Summary
For the 2000 Ford Explorer, the transmission was a four-speed automatic (the 4R55E family) paired with either the standard 4.0-liter V6 or the optional 5.0-liter V8. It was not available with a manual gearbox in the U.S., and it served both two- and four-wheel-drive models with electronic control to manage shifts. Ongoing maintenance is essential to keep these transmissions performing well in aging units.
