How Do You Diagnose Transmission Problems?

By Mister Transmission

Diagnose Transmission Problems

Diagnostics is the process by which you determine the cause of (diagnose) a transmission’s problem. Diagnostics is obviously a very important practice because without it, fixing any transmission problem would be complete guess work. You can have the most talented technicians in world trying to fix a problem, but if they don’t know what the problem is, they are not going to be able to fix your transmission. So how do technicians diagnose transmission problems?

Transmission problems

Transmission problems can arise from a plethora of causes. Sometimes it is simple enough to determine the problem. If you’re seeing transmission fluid underneath your vehicle after every time you park, you likely have a leak. But some problems, especially computer problems with computerized transmissions, can be especially tricky. That’s why you need professional and well-trained transmission technicians working on your transmission to diagnose the problem.

Technological diagnostics

At the best equipped and modern transmission service centres (such as Mister Transmission) you will find cutting-edge diagnostic equipment. This equipment is crucial because it allows technicians to offer you the fastest and most accurate findings with regards to just what is going on inside your vehicle’s transmission. Like all technology, transmissions have changed a lot in recent years. Today’s vehicles come equipped with complex computer systems. And modern diagnostic technology can communicate with your automobile’s computer systems to determine your specific transmission problems.

The first step

The first step in determining your transmission problems consists of the technician connecting the diagnostic equipment to your vehicle’s on-board computer. This will produce a code stating where the problem lies. Following this, the vehicle should be taken for a test drive so that the technicians can monitor the transmission’s behaviour in real-time. While more comprehensive and hands-on evaluations might still be necessary, today’s technology is an integral tool in determining the best starting point for further investigations.

Mister Transmission’s diagnosis of transmission problems

When a Mister Transmission technician hooks up a scanner to your car’s computer system, within seconds, he may read a diagnostic trouble code like “P0732,” which refers to an incorrect gear-two ratio. What on earth does this mean? Put simply, this means the transmission didn’t shift into second gear properly.

After retrieving this information, the technician will conduct a short test drive and monitor all of the input and output speed sensors data, as well as the car’s engine control unit. This is the  unit which is responsible for sending and receiving that data. Upon completion, our certified experts can determine the exact cause of the vehicle’s problems, and then figure out if the problem is the transmission or a digital malfunction between the car’s computer and the transmission.

Complex transmissions = complex problems

The transmission is a very complicated and sophisticated piece of equipment. And this is even truer of the transmissions found in newer vehicles. There is no one-size-fits-all solution to transmission problems, and anyone who says otherwise is either ignorant or a charlatan. To ensure your vehicle’s well-being –and yours– you should only trust certified experts to diagnose your transmission problems.

I had my 2007 Toyota Rav 4 transmission rebuilt almost 2 years ago. Decided to bring it back for a transmission fluid change and for another check before the warranty expires. What I didn’t tell them is that there’s already a leak (my neighbour told me). I’m giving this business a 5 star review because they are honest. They told me it had a leak and they had to replace the seal, and it was still under warranty. Wow! Thank you!!!

I have a 2015 Mazda 3 with automatic transmission. It is having jerking issue at 2nd gear when the car is cold. One of my known mechanic suggested Ken for transmission issues. I went there and parked my car overnight to make sure it is cold. In morning, Ken drove it and figure out instantly it was a computer mechanism trying to save fuel by engaging clutch and gear differently, which is normal and I should not spend any money on it. I liked Ken's experience and knowledge and his guidance which saved me going broke.

Had a leak from the pan and front seal on my transmission. Despite being busy these guys were able to seal up the pan within one day. No leaks from the pan. I decided to hold off on the main seal as it is a slow leak and I'll deal with it in the winter when the cars in storage. Thanks
