Finding the correct Lincoln transmission for a 2004 LS starts with matching the engine, transmission type, drivetrain and vehicle identification information. This application uses a 5-speed automatic transmission for the 3.0L 6-cylinder configuration.
2004 Lincoln LS Transmission Overview
The 2004 Lincoln LS was offered with a 3.0L DOHC V6 engine paired with a 5-speed automatic transmission. For the 6-cylinder application, Ford parts information identifies the transmission as the 5R55S, designed for the rear-wheel-drive LS platform.

Need a Transmission for Your Lincoln LS?
If your Lincoln LS transmission is slipping, shifting poorly, making unusual noises or no longer engaging properly, replacement may be necessary.
However, transmission problems can sometimes be related to fluid condition, electrical components, sensors or other drivetrain components. A proper diagnosis can help determine whether the transmission itself needs replacement.
For a replacement unit, the most important step is confirming the exact vehicle application before purchasing.
How to Identify the Correct Transmission
There are several details you should have available when looking for a transmission for a 2004 Lincoln LS.
Check These Details:
- Year: 2004
- Vehicle: Lincoln LS
- Engine: 3.0L V6
- Cylinders: 6
- Transmission: Automatic
- Transmission family: 5R55S
- Drivetrain: Rear-wheel drive
- VIN: Complete 17-character VIN
- Transmission identification tag: Check the existing unit when possible
Ford parts information specifically lists the 5R55S automatic transmission with the 3.0L DOHC 6-cylinder LS application.
2004 Lincoln LS 6-Cylinder Transmission Fitment
The 6-cylinder Lincoln LS uses a 3.0L DOHC V6 and rear-wheel-drive layout for this application.
The transmission should therefore be matched according to the complete application rather than simply searching for any automatic transmission from a Lincoln.
A transmission from another vehicle or a different LS configuration may look similar while having differences in internal components, calibration, connectors or identification codes.
Always verify the transmission code and VIN before ordering.
Signs Your Lincoln LS Transmission May Need Replacement
Some common symptoms that can indicate a transmission problem include:
1. Delayed Engagement
The vehicle takes longer than normal to engage after selecting Drive or Reverse.
2. Slipping
Engine RPM increases without a corresponding increase in vehicle speed.
3. Harsh Shifting
The transmission may produce noticeably hard or abrupt gear changes.
4. Gear-Shifting Problems
The vehicle may have difficulty selecting or maintaining a particular gear.
5. Unusual Noise
Whining, humming, grinding or other unusual noises can indicate a drivetrain problem.
6. Transmission Fluid Problems
Low, contaminated or leaking transmission fluid can contribute to transmission problems.
These symptoms can have multiple causes, so proper diagnosis is recommended before replacing the complete transmission.
