FAQs—Dodge W100 Series
I hear some kind of a chattering noise whenever I shift gears, and it feels like it also slips. What could be the cause, and how do I resolve it?
Chattering or slipping when shifting gears is a common problem with automatic transmission system, and it is often caused by contaminated transmission fluid. Slipping usually happens when the temperature is cold and when you climb uphill. Such a problem may also cause delayed shifting and rough initial engagement in D or R. Do not continue running your vehicle in that condition in order to prevent more serious internal damage. You have to drain and refill the transmission with new fluid as soon as possible. You may also need to clean or replace the filter.
To avoid problems related to low transmission fluid level, check its amount after every few months or during engine oil change. Also inspect the color and smell of the fluid for you to determine if fluid change is already required. Red or pink color indicates good fluid, while black or brown color with the burning smell needs maintenance. Recommended transmission fluid change is normally after every 15,000 to 60,000 miles, depending on the operating conditions. Severely operated cars may require more frequent changing of fluid.
The engine vibrates abnormally, and I hear loud pings. Tell me what is happening with my Dodge W100 Series, and what do I need to do to stop these things?
Running with low octane fuel is the most probable cause of abnormal engine vibration and pinging.This condition causes the compression to spontaneously ignite low octane fuel in another part of the combustion chamber. Pinging or knocking happens when the latter meets the flame from the normal combustion process. You will have to switch to higher octane fuel, or have the engine adjusted in order to use the available fuel.
There's an unusual noise in my Dodge W100 Series, and I don't know where it's coming from. The engine also overheats even if I often refill with coolant. Can you help me determine the cause, and how to solve these problems?
Four possible causes indicate all of the three signs that you just mentioned, all of which are with the cooling system. They could be due to air trapped in the system that needs to be bled out. You may also find out that they are caused by loose fan belt or broken fan or fan shroud. If it is the belt that is problematic, tightening might all be that is needed, while a replacement will be necessary if the fan or its shroud is broken. You may also trace the problems back to faulty water pump because such definitely leads to overheating and would cause noise if its bearing is defective. Replacement is also the solution to this. Backflush and refill new coolant mix to make sure dirty coolant will not damage the new one. Also test the fan switch and motor because one of them could also be the culprit. Replace one or both as necessary.
