Hummer Maintenance Procedures - Common Additional Services
The air filter accumulates dust and debris and should be replaced to protect the engine and maximize fuel economy. For optimal engine performance and longevity, replace every 1 year or 15,000 miles.
Automatic transmission fluid becomes heat fatigued and accumulates moisture over time which can lead to automatic transmission damage if not serviced regularly. It should be replaced every 2 years or 30,000 miles.
Automatic transmission fluid becomes heat fatigued and accumulates moisture over time which can lead to automatic transmission damage if not serviced regularly. The filter should be replaced at this time a well. This service should be performed every 2 years or 30,000 miles.
Brake fluid accumulates moisture and contamination from component wear over time and unless replaced every 30,000 miles or 2 years, can cause brake system damage.
Engine coolant breaks down, gets rusty and becomes contaminated with debris from component wear over time and can cause engine or cooling system damage if not replaced every 2 years or 30,0000 miles.
Differential fluid breaks down and becomes contaminated with moisture over time and can lead to differential damage from a lack of proper lubrication. It should be replaced every 2 years or 30,000 miles.

I have a transmission slippage issue that I believe has lead to a second engine failure (First for excessive oil consumption at around 80,000 Kilometers vehicle mileage) I experienced a random intermittent problem that occurs usually when I go to accelerate from a traffic signal the speedometer drops to zero and my automatic transmission feels like the clutches are slipping. I then nurse the vehicle to the side of the road, turn off the engine and then re-start. The problem usually goes away.... |
