Transmission Slipping:
Early models and heavy-duty use can sometimes lead to transmission slipping or harsh shifting, often due to fluid breakdown or valve body issues.
Radiator Leaks:
Radiator plastic end tanks can degrade over time, leading to coolant leaks.
Ignition Coil Failure:
Individual ignition coils can fail, leading to misfires and rough running.
