• Injector Failure: The fuel injectors can fail, causing rough idle, poor fuel economy, and black smoke from the exhaust. Replacing the injectors is the solution, with an estimated cost of $1,000 - $2,000+.
• Head Gasket Failure: The head gasket can fail, causing coolant leaks and overheating. Replacing the head gasket is the solution, with an estimated cost of $1,200 - $2,000+.

Transmission

E4OD 4-Speed Automatic

• Overdrive Failure: The overdrive unit can fail, causing the transmission to slip or shudder in overdrive. Replacing the overdrive unit is the solution, with an estimated cost of $800 - $1,500+.
• Shift Solenoid Failure: The shift solenoids can fail, causing shifting problems. Replacing the shift solenoids is the solution, with an estimated cost of $300 - $600+.
