Gearboxes deliver power from the transmission to the wheels. A vehicle can have three different gearboxes including front differential, rear differential and transfer case.
Extreme high operating temperatures can cause thermal breakdown of the differential fluid leading to a loss of lubrication and deposit formation. This can cause gears to grind while leaving behind metal shavings and other debris.
Our Valvoline Differential and Transfer Case Services (Gearboxes) are thermally stable and help remove deposits - while working to keep new ones from forming. This helps ensure proper gear lubrication.
I went in for a gear box service. I usually do most of the work on my truck myself but did not feel like doing this stuff. I know a fair amount about my truck and repairs and I was impressed by the knowledge of the workers there. When I asked one employee a question I knew the answer to and he did not know the answer, he went and asked another employee and returned with the correct answer. This made me feel very good about the level of service and the work performed.
The Service Center Manager was very knowledgeable in explaining that my newly purchased used jeep probably should have a few fluids changed. My gear boxes needed to be flushed because when I switched from 4x4 to rear wheel drive it was getting stuck. I'm always leery of oil change places that you go into for a simple oil change and they tell you that you need additional services. The manager made me feel really comfortable that they were services I really did need. He was right as soon as it was flushed I tested my 4x4 and it changed gears with no problem. Now I only will go to this service center for any major maintenance service. I can trust this manager and everything he has recommended has made my car better and me feel more confident that my jeep will run well into the hundreds of thousands of miles range.
The staff was great. Helped me with my oil change and recommended me to have my transmission checked. It's nice to know they can inform you on those extra maintenance services as I wouldn't have thought about having that done. I never had it checked before so it was worth it.
