There should be an output seal between the transmission and the transfer case has an input seal with a gasket in between. If any of these are bad it may leak transmission fluid. I would recommend having a certified technician,...

Hi there, the short answer to your question is no . A PCM with a P0601 (which is a memory module error in the PCM) cannot reliably retrieve codes for the codes you list (P0118 - coolant temp sensor, P0123...

Hi. The next step to take is check the engine for vacuum leaks and check for any loose or broken hoes. I would also check the pcv valve and check the level of the transmission fluid. The transmission could also...

Hi Christian. Thanks for the additional information. Based on what you've indicated, I would suspect that you have worn out wheel bearings causing the vibration, especially if you are experiencing the vibration reduces and when you make a turn. However,...

Remove the timing chain cover and see if the chain is intact. If the chain is broken, then either the chain can bind up on the crankshaft sprocket or the pistons can come in contact with the valves when they...

Hi There, A number of sensors may become faulty in hot weather conditions which will ultimately cause the check engine light to come on. As the weather gets hotter, many sensors, fuel injectors and other components such as ignition coils...

Hi, thanks for writing in. It sounds like you have the NV233 transfercase. The transfercase control module receives input from various sensors and switches, including the tranfercase range switch. It then uses this information to engage the transfercase actuator/encoder motor...

Hello. This may be a faulty starter relay. The starter relay is a small unit usually in the fuse box that directs power to the starter from the battery. When this fails, it may cause a clicking sound and will...

Hello, thank you for writing in. You are on the right track. The power steering pump is a very common place to develop leaks. Hoses, lines, the rack, and the gear box are also common places you will find a...

Hello - the smell and "hot" symptoms you describe suggest your rear brake is dragging on that rear wheel. This could be an emergency brake cable which is not releasing, or a frozen brake cylinder or caliper. I recommend a...

Hello, thank you for writing in. The vehicle is likely having issues with the battery. When the alternator fails, the vehicle does its best to rely on the battery, which puts it under an incredible amount of stress. This likely...

Hi. There are a few other reason why the AWD is not working on your suv. In a lot of cases the transfer case for the AWD stops working because either the electronic sensor or parts are bad or the...

Hey there. The most likely problem is the bulb holder / socket itself. It may look fine but probably has a crack or break internally. Also possible (but rare) is the circuit board within the tail lamp housing itself. I...

I'm guessing the codes is P0128 Coolant Thermostat (Coolant Temperature Below Thermostat Regulating Temperature). The code and the symptoms you are experiencing may or may not be related. The powertrain control module (PCM) determines operating temperature via the signal from...

The first thing is a proper diagnosis will not only verify the complaint but will locate the cause of the problem for you so you can decide to fix it or not. When an engine overheats for no apparent reason...
