To Flush or Not to Flush

One of the most common questions we receive is how much for a transmission flush? Having specialized in nothing but driveline repair for 25 years we DO NOT recommend ever flushing a transmission. Why you might ask?

All too often we receive calls from the customer bringing their vehicle into a shop, being sold a transmission flush, and then having issues quickly or even immediately after the flush. We have even heard stories of the customer not being able to drive the vehicle off the lot because the transmission is having so many issues. They call assuming the shop messed up the service and asking us to verify that.  The unfortunate part, you can’t hold the shop liable for performing the flush that caused these issues because they correctly performed the flush and could not know for certain it would cause a failure.

You may be asking yourself why this happens?! How could a shop sell you a service that should be preventative maintenance that then causes it to have failures? To answer this question you need some background information. Transmissions operate off of frictions plates and hydraulic oil pressure, such as clutch packs. These clutch packs naturally shed some of this material in normal operation; we call this “normal wear” in the industry. The purpose of the filter is to catch this material and store it. When flushing the transmission this material can wind up stuck in the valve body or somewhere else inside the transmission. This means it will need to be rebuilt to correct this issue; your 50 dollar flush is now a few thousand dollar repair.

So what do we recommend? A simple transmission service. This means dropping the pan, inspecting it, allowing the fluid to drain, and replacing the filter with a new one, a new pan gasket, and filling it up with fresh fluid. The price to do this ranges from $125 to 250; depending on the vehicle. If you would like more information about this feel free to five us a call at 303-733-8494.

Customer service is our main goal and we hate hearing these stories from new or old customers! While it might t be more expensive for a service, it will not cause the damage that flushing can.

When was the last time you serviced your transmission/transaxle?

Transmission/transaxle fluid is like the blood of the transmission. Instead of carrying nutrients it lubricates all of the transmissions moving parts, of which there are thousands! Without proper lubrication the transmission begins to wear on parts of itself. This causes metal shaving to begin to feel the transmission. This turns the fluid from a lubricant into an abrasive. Which in turn begins to chew on the seals and can cause leaks. It also continues to wear down the internal parts of the transmission. A fluid and filter change insures that the fluid is lubing properly and replacing the filter makes sure to keep the metal contamination in the filter and not causing damage by floating in the fluid and further chewing into the internal parts of the transmission.

Call today and schedule a fluid and filter change for your transmission/transaxle. As we head into the winter months getting stuck in the snow is almost inevitable. The forward and reverse rocking motion that helps get your car unstuck from a snow bank is very hard on your transmission. Help insure that it has good lubricant and remove the old contamination with a service before the snow comes! This will help the transmission operate better thus ensuring a longer life for your transmission. Call or email with questions or to make an appointment. Services range from $125 to 275 for synthetic transmission fluid.

Why is Wizard’s FREE transmission diagnostic important?

Here at Wizard Transmission we offer a FREE transmission/drivetrain diagnostic scan. This inspection takes about three to four hours to complete but that amount of time allows us to really examine the vehicles transmission. We start off by using a computer to examine the vehicles electrical system for the transmission. Next, we look at the level and condition of the fluid. The vehicle is then taken on a drive by one of our technicians where we do our best to duplicate the customer’s problems. After the vehicle is driven we bring it into the shop and put it on a life. We then drop the transmission pan or take out the inspection plug. This allows us to examine the overall condition of the transmission. Once this is complete we have a better idea of what is going on and can give an accurate estimate for repair. At this point the customer decides whether to come pick up the vehicle, again FREE of charge, or to proceed with the repair.

When deciding on any major automotive repair it is ALWAYS a good idea to start off with some kind of diagnostic scan. Automobiles are very complex machines and a quality diagnostic scan will save you hundreds maybe even thousands in unnecessary repairs.



How is a transmission cooled?

In almost all vehicles with an automatic transmission there is a transmission cooler placed inside the radiator. Most standard transmissions do not make as much heat and therefore do not have a cooler. The cooler for the automatic transmissions are placed inside the radiator, the reason behind this is the antifreeze provides the perfect environment. It warms the transmission up with it’s cold and keeps it from getting too hot in extreme heat.

An auxiliary cooler is a completely separate transmission cooler that is typically mounted somewhere in the front of the AC condenser. While these coolers are helpful they are not quit as effective as the coolers that are mounted inside the radiator. The reason? The auxiliary cooler is cooled by air flow while the cooler inside the radiator is surrounded by antifreeze which is a controlled environment.

For this reason we recommend never eliminating the cooler inside the radiator. If you want to increase cooling capacity we recommend adding an auxiliary cooler. This way the transmission is being cooled by two different coolers; one with antifreeze and on through air flow.

In very few cases the cooler for the transmission is located externally from the transmission.

Heat Kills

If your vehicle has an automatic transmission then you need an AUXILIARY cooler. What is this? All automatic transmission come with a small built in transmission cooler which is placed inside the radiator. This cooler is rather small and for hot days driving in the mountains or even through the city the transmission fluid temperature heats up considerably. When the transmission fluid becomes too hot varnishes form, seals harden, plates slip, and the seals and clutches burn out. Adding an auxiliary cooler helps insure the transmission temperature stays within a safe range.

An auxiliary cooler is a cooler that can be added on to any vehicle. It is specifically for the transmission and keeping the fluid temperature lower, it is essentially a radiator for the transmission.  Some newer vehicles, especially towing vehicles, already come equipped with an auxiliary cooler but it never hurts to check!

Make an appointment to bring your vehicle in for a FREE auxiliary cooler diagnostic. If your vehicle is not equipped with an auxiliary cooler we will be more than happy to give you a quote.

Why Can’t We Quote Transmission Repair Cost Over the Phone?

20-or-so years ago, there were only maybe a dozen different transmissions on the road. Every transmission repair shop had a good stock of rebuilt units on hand. There were almost no updates necessary, and even if something unusual failed, most shops had a good supply of used parts on hand to replace it.

Today there are more than ten times that many transmissions in use, with new ones showing up all the time. Many of those transmissions have several different variations or calibrations, with as many as a dozen modifications necessary. What’s more, today’s transmissions are computer controlled, which means even though your transmission may not be working properly, there?s a good chance the root cause of the problem doesn’t have anything to do with the transmission itself.

Mag WheelsTo provide you with an accurate assessment of your transmission’s condition and give you an honest estimate for repairs, technicians must perform a series of rigorous tests. They must identify which transmission is in your car, and which version of that transmission it is. Then they have to identify the specific problem, and isolate whether it’s in the transmission or the computer system.

Finally, they have to determine the likely causes for the problem, based on a logical diagnostic process. Once they have that information, the shop is able to give you a more accurate explanation of your car’s condition, and put together an accurate estimate of the costs to repair it. There’s just no way to do all that over the phone.
