Introduction
This manual provides comprehensive instructions for the installation, operation, and maintenance of the TRANSGO 5R55W Shift Kit. This kit is designed to address common transmission issues and enhance performance. Please read all instructions carefully before proceeding with installation or operation.
The TRANSGO 5R55W Shift Kit is engineered to fix lockup complaints, reduce the need for new pump and valve body components, and resolve issues such as "won't move cold" noise. It includes a new pump valve assembly, lockup valve, pump alignment tool, and EPC relief assemblies.
Product Components
Image 1: Overview of the TRANSGO 5R55W Shift Kit components. The image displays the product packaging box and an assortment of small metal and rubber parts, including seals, springs, valves, and a pump alignment tool, laid out on a white surface. These components are essential for the transmission valve body rebuild.
The TRANSGO 5R55W Shift Kit includes the following key components:
- New Pump Valve Assembly
- Lockup Valve
- Pump Alignment Tool
- EPC Relief Assemblies
- Various seals, springs, and small hardware necessary for the rebuild.
Setup and Installation
Important: Installation of this shift kit requires advanced mechanical knowledge and specialized tools. If you are not confident in your abilities, it is recommended to seek professional assistance.
- Preparation: Ensure the vehicle is safely lifted and supported. Drain the transmission fluid and remove the transmission pan and valve body according to the vehicle manufacturer's service manual.
- Valve Body Disassembly: Carefully disassemble the valve body, keeping all components organized. Refer to the detailed diagrams provided with your specific TRANSGO kit for component identification and placement.
- Component Replacement: Replace the specified valves, springs, and seals with the new TRANSGO components. Pay close attention to the orientation and placement of each part. The kit addresses common issues such as "Pump Align Reducer Seal & Bushing Failure."
- Band Adjustment: This is a critical step. Locate the two bands that require adjustment. Tighten the lock nuts until you feel resistance, then back them out exactly two turns. Relock the nuts to secure the adjustment. This accounts for wear in the band over time and contributes to smoother shifts.
- Valve Body Reassembly: Reassemble the valve body, ensuring all components are correctly seated and torqued to specifications.
- Installation into Transmission: Reinstall the valve body into the transmission, followed by a new transmission filter and the transmission pan.
- Fluid Refill: Properly top off the transmission with the recommended Mercon V fluid. Ensure the fluid level is correct according to the vehicle manufacturer's guidelines. It is advisable to have extra fluid on hand to avoid delays.
Note: Allow an entire day for the installation process to avoid rushing and potential errors.
Operating Considerations
After installation, the transmission should exhibit improved shifting characteristics and address previous issues such as P0741 (lockup complaint) and P0732, P0733, P0735 codes. The vehicle should experience smoother and more responsive gear changes.
- Initial Test Drive: Perform a cautious test drive to ensure proper operation. Pay attention to shift points and overall transmission behavior.
- Fluid Level Check: Recheck the transmission fluid level after the test drive and top off if necessary.
Maintenance
Regular transmission maintenance, including fluid and filter changes, is crucial for the longevity of your transmission and the continued performance of the TRANSGO Shift Kit. Follow your vehicle manufacturer's recommended service intervals.
- Monitor Transmission Fluid: Periodically check the transmission fluid for proper level and condition.
- Address Issues Promptly: If any new or recurring transmission issues arise, consult a qualified technician.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| P0741 Code (Lockup Complaint) | Stuck or worn lockup valve, inadequate fluid pressure. | The TRANSGO kit is designed to address this. Re-verify correct installation of the new lockup valve and EPC relief assemblies. Ensure proper band adjustment. |
| "Won't move cold" noise | Issues with pump valve assembly or fluid circulation. | The kit includes a new pump valve assembly. Confirm correct installation and proper fluid levels. |
| Rough or delayed shifting | Incorrect band adjustment, low fluid, or incorrect component installation. | Check transmission fluid level. Re-verify band adjustments (two turns out from resistance). Review installation steps for any missed details. |
| Codes P0732, P0733, P0735 | Gear ratio errors, often related to internal transmission issues. | The kit aims to improve internal hydraulic integrity. If codes persist, further diagnostic by a professional is recommended. |
