Common Issues and Its Solutions of Transmission
Overheating
Symptoms: Slipping of hand movement, failure to shift in another gear and late engagement
Solutions: Check the fluid level of transmission and verify the condition of radiator to ensure the cooling lines are clear.
Shifting Problems
Symptoms: Having difficulty because of harsh shifts or delayed engagements.
Solutions: Check the faulty codes using OBD-II diagnostic scanner and consider a valve body replacement, if necessary.
Torque Converter Issues
Symptoms:S Stalling, odd noises or slipping.
Solutions: Make a quick thorough inspection of torque converter for any sign of failure or clutches wearing out.
Fluid Contamination
Symptoms:There is gritty feel in transmission fluid or discoloration.
Solutions:You need to inspect the reservoir regularly and change the fluid on regular interval.
Electronic Failures
Symptoms:
Verify if the check engine light is activated.
Solutions:Test sensor, TCM and update or replace the faulty electronic components.
Maintenance Tips of 68RFE Transmission
Fluid Changes
You need to change the transmission fluid after every 30k to 60k miles as it depends on driving conditions. And you should always use fluid as per the manufacturer-recommended fluid type.
Inspecting Filters and Coolers
To prevent from clogs and overheating, replace the transmission filters and inspect external coolers.
Regular Diagnostic
Use an OBD-II scanner to read codes on regular basis and catch the issues before they escalate.
In The End
In summary, we conclude that 68RFE transmission is reliable and robust automatic transmission. With proper maintenance and update it can be last for many years as it is the popular choice among truck drivers.
