There’s an old saying, “Sometimes the easiest way to solve a problem is to stop part of it.” We’re not sure who said it but it must be a car guy.

This is because it often seems that many of the most common problems with cars and the cars we love that auto technicians encounter are done by us. You know that problem you’ve been struggling with for months, and then when you get the solution, you want to beat yourself up because it’s so easy?

The Difference Between Transmission Fluid And Differential Fluid

One of the places where we see it most often is the bus. So we contacted the experts at PerformaBuilt Transmissions about the common problems they face when helping racers and performance enthusiasts. The guys there were very knowledgeable and willing to share their years of experience. Here are the most common transmission problems we see when it comes to automatic transmissions and cars and trucks.

The manual transmission reservoir is wide, but not too deep, so if the pan is slightly off, it can make a big difference in the fluid level.

Most people don’t realize that the device’s signal is not clear. When you consider the length and width of most transmission cases compared to their depth, it’s clear that even a quarter-inch dipstick reading means the fluid transmission is too low. In work situations where fluid requirements can be excessive, this can quickly lead to serious injury.

It is best to never assume that the oil fluid blade is inside the box itself. To check yourself, put the plate in place, place it on the pot, and make sure that the full mark is on the lower edge of the device (where the pot is raised). If your full mark is low, just create a new mark on the board. The easiest way to do this is to use a file to cut a little off the edge of the gauge.

When the disk is properly checked and labeled, you can be sure that you have enough fluid even in the most difficult conditions.

In daily driving, you should change the transmission fluid and filter it annually. Even if the car is over the weekend, the fluid should be changed every 12,000 miles.

Transmission fluid is similar to motor oil in that it chemically degrades over time. Transmission fluid serves many purposes. The first is the hydraulic intermediate that allows the transmission to work. Second, it continuously lubricates the transmission and reduces wear. Third, it cleans the transmission as it rotates. Finally, it absorbs the heat generated by the transmission and allows it to escape through the case or transmission cooler. Although transmission fluid’s performance as a liquid fluid does not change over time, it can lose its lubricating, cleaning, and heat-dissipating abilities over time as the fluid degrades.

All mechanical objects deteriorate slightly with use, and the resulting damage contaminates the fluid, which actually damages the part it is meant to protect. That’s why we specifically mentioned the filter change. Before draining the transmission is a good method, unless you also drain the pot and change the filter, without removing the accumulated debris, the filter will eventually get dirty. A clogged filter restricts fluid flow, which will damage the transmission. No one will change the engine oil and get rid of the filter, but many times we see transmissions that are cleaned regularly but still burn because of a clogged filter.

How To Check And Add Fluid To Your Automatic Transmission

While the coolant in your radiator may be sufficient for the average passenger car, any vehicle built for work will often require more cooling capacity. Cars with high performance engines, and especially cars with high performance transmissions, need more cooling to keep the transmission warm. The preferred air conditioner is a separate outdoor cooler with a fan to ensure that there is always plenty of air circulating through the cooler. The best temperature for most automatic transmissions is 165 to 220 degrees. In general, cold is better. Heat is the worst enemy of any transmission.

Let’s start by installing the torque converter. Before you get into gear, take the time to go ahead and add ATF to help with your first ignition. Pour one liter of fluid into the converter before placing it in the transmission. Once the transmission and torque converter are installed, refer back to the previous chapters in this article to verify the correct plate reading.

The torque converter must be fully seated in the transmission before attempting to engage the engine transmission. Do not force the transmission to the block too much by tightening the bell bolts. If not, the torque converter may not be fully seated in the transmission. It’s small, but you should hear a loud click when the switch is down and seated properly. Start by setting the torque converter on the transmission output shaft to constant pressure. You will feel it go past the old seal, then through the pump bushing and finally into the pump. It should enter the pump rotor and spin a little.

There should be 1/8 to 3/16 inch of clearance between the torque converter and torque converter when everything is closed. If you have very little, it is okay to cheat.

When it comes to the torque converter output, there should be between 1/8 and 3/16 inch of clearance between the flex plate and the torque converter when the transmission is driven into the engine. If there is too much space, add shims between the torque converter and remove it. If it is slow or if your transmission disengages the torque converter, reset and reset. A gap that is too small means that the carrier transmission is out of alignment and the future could be a damaged engine.

When the transmission is completely secured to the block and chassis, pour it into a 5 or 6 liter fill tube. Start the engine and add fluid until the dipstick is full. In most modern transmissions it will be 11 liters or more. Do a short test and let the car sit for a while (about half an hour) and check again. Potentially trapped air pockets are released during the test. Once you’re sure the transmission is filled with the correct fluid, you’re good to go.

In early transmissions such as the 700-R4 and 200-4R, one of the most common causes of failure is faulty wiring. Unlike the new electronic 4L60E, which has an electronic control solenoid (EPC) that monitors line pressure via a separate sensor mounted on the vehicle, the 700-R4 and 200-4R uses a cable and a fulcrum device, the throttle valve. ) to touch. in the transmission to monitor the line pressure. As the pressure increases, this valve increases the line pressure for more holding capacity.

From the TV mount on the transmission box there will be a wire that runs and attaches to your radiator or carburetor. After fixing it, remove the pan and adjust the cable so that when the gas pedal is pressed to the floor, the TV is completely washed. When the accelerator pedal is released (engine idle) and the throttle valve is relaxed, the transmission support arm should rest on the valve without movement. This will provide quick response and healthy holding power in every rev range, as well as durability.

Different Types Of Car Transmissions

It’s safe to say that since the earlier transmissions were on the road, the aftermarket has produced wiring kits to simplify this process and make repairs easier. You can check out the PerformaBuilt YouTube page for more information.

Newer cars adjust the pressure on the transmission line through the ECM, making the adjustment small. One of the most popular techniques for tuners is to apply line pressure to get a sharp change. This is fine in most cases, but you need to be careful. If the line pressure is set too high, it will cause significant changes that will actually destroy the internal components. For example, the GM 4L60E input drum is aluminum and the steel is steel. When the “slam” relay changes,
