FAQs—Chevrolet V20 Suburban
Bought this used Chevrolet V20 Suburban in a nearby dealership. It was running fine for quite some time now even though I'm actually the third to drive it. However, it started acting out a few days ago. It won't shift into 3rd gear; it's an automatic transmission. Any idea what's wrong with it?
A lot of shifting problems in an automatic transmission system are caused by a malfunctioning shift solenoid. The shift solenoid is the one responsible for regulating fluid pressure. When the transmission is getting too much fluid pressure, you will experience rough shifting. On the other hand, not enough fluid pressure will cause the clutch plates to overheat. Indications that something's wrong with the shift solenoid include a delay in shifting, transmission that does not downshift, and a transmission that does not shift into the right gear. So your Suburban not shifting into 3rd gear has to do with your shift solenoid. You might want to check it out and have it replaced at once.
This Chevrolet V20 Suburban has been having problems with the battery. I tried turning on the radio once while the vehicle was off and I noticed that the battery power depleted within 2-10 minutes. What could be causing this problem?
A dead battery or one that gets easily drained is usually caused by an excessive current drain that has gone undiagnosed. And that is maybe what is happening to your Suburban's battery. What you need to do here is to identify where the drain is coming from because it will continue to drain any battery you mount in that engine bay. Causes of this drain include lights that remain on (trunk and hood lights, interior lights, brake lights, etc.) or relays that may be stuck on. Sometimes, modules that are not going to sleep mode or are not powering down are also causing current drain. For example, if the fuel pump relay sticks, it may keep the fuel pump running long after the engine has been shut off. Any accessory such as DVD player, game console, or phone charger left unplugged may also be pulling power from the battery. What you should do is unplug all power receptacles in the car and then look for a malfunctioning relay or module that may be causing the drain. Replace them if necessary.
My Chevy V20 has gone bad recently. I've been driving this vehicle for many years now without any hitch. However, the other day, it just wouldn't start. Any idea what I'm up against?
You might be having a dead battery, poor battery connections, defective starter, or failing starter solenoid. To determine the reason why your car is not starting, you have to pay attention to what happens when you turn on the key. If the engine won't crank and nothing happens when you turn the key, it could be because of a dead battery. There are parasitic drains in your vehicle that use up charge even after you turn the engine off. The solution is to charge the battery with the alternator during everyday driving. Poor connections can also cause a no-start, so make sure that the cable connectors and the top of the battery terminals are free from buildup and corrosion. A defective starter or solenoid can also be the problem. In this case, replacement of either of the two will be necessary.
