How to tell if your transmission is going out
Here are some slipping transmission symptoms I will be outlining a few things that will allow you to know whether or not your automatic transmission in your car or truck is slipping, so this is how it works.
You need to pay attention to the tachometer which is the gauge that shows you the RPMs of the engine and the speedometer which is a gauge that shows you the speed of the car, you need to pay attention to those two things together.
This is what you’re going to do, you’re
going to put your car truck and drive it, and you’re going to drive now technically speaking, when you’re pushing the gas pedal your rpm so you should increase and your speedometer should increase so as the engine speed is increasing the car speed should increase, the car should be going faster and then obviously if the car up shifts the engine speed and the RPM is going to go back down but technically speaking the RPM should continually go up and then the speedometer and the speed of the car should also continue to follow that increase now here’s what happens if you have an automatic transmission that is slipping.
Basically the transmission is what connects the engine to the wheels, when the engine is turning and spinning, it allows the transmission the power of that spinning to be transferred to the wheels now if you have a slipping automatic transmission the power from the engine will not properly be transferred to the wheels, it will slip so this is what it’s going to sound like on the tachometer and speedometer you’re going to push the gas pedal, the speedometer is going to increase but your car speed and your speedometer is not going to increase, okay so the tachometer is going to go up and the speedometer is not going to go up nearly as quickly, then you’re going to sort of hear the engine revving up, it’s going to sound like this but your speedometer won’t be moving forward, your car will not be going faster so that’s how you tell.
Now if you are unsure about it, go to a road that has a lot of space and what I would recommend is just flooring the gas pedal and you’ll notice that if you have a slipping automatic transmission the tachometers RPMs will increase and the speedometer will barely be moving, if your transmission is severely slipping, what will happen is once again the tachometer is going to increase, but this parameter will not move at all.
If your car literally does not move at all, if your transmission is in really bad shape with regards to its slippage, so that’s basically a very simple test that is, those are the symptoms of a slipping automatic transmission similar to what it would sound like if you had a slipping clutch on a manual transmission.
Those are the symptoms and that’s exactly how you can tell, pay attention to your tachometer and speedometer I would recommend to do this safely having someone beside you, and as you drive the car or truck and have them pay attention to your tachometer and speedometer just so you can keep your eyes on the road, that is my safety advice but that’s basically it, if you have any questions about any issues your having with your Dodge, Chevrolet, GMC, Toyota, Nissan, Honda, Hyundai, KIA, or Ford truck, just give us a call at Boise Transmission Repair 208-297-5202
How can you tell if your transmission is bad
How to tell if your automatic transmission is actually starting to go out, now the automatic transmissions in most modern cars are very complex, they’re computer run, most don’t even have dip sticks to check the fluid level, so how do you know when they’re starting to go out.
Now years ago I had a customer who came to me from a different mechanic, the other mechanic had replaced the transmission in his car, but it still had the same problem, at higher speeds the transmission would drop out of top gear and go to the next lower gear, and it wasn’t shifting right, he thought it was the transmission so he replaced it and guess what, it did the same thing, so when he brought it to me I first did a scan of the whole vehicle, turns out that he had a misfire, all he had was a bad ignition coil on one of the cylinders of the engine.
You might think hey what is a bad spark plug coil have to do with the transmission shifting, well modern cars are very complex, they have a really tight relationship between the engine and the transmission and the drive-train, it’s all monitored by computer sensors and in this particular vehicle, when it senses a misfire, the computer software automatically takes it out of the top gear which was an overdrive gear and puts it into the next one, it’s designed to do that, so in this case the previous mechanic charged this guy for a new transmission, when all’s it needed was a $80.00 ignition coil that was the whole problem, now you don’t want to pay for such an unneeded expensive repair it was thousands of dollars, so I’m going to show you how you can tell if your transmission really is starting to go out.
Now in the beginning I showed you the scan tool and it showed a code of P0730, I hooked it up to this Toyota Tacoma, right away you know, ok it’s got a problem in the transmission, now unfortunately there’s over a dozen different things that can cause this particular code, that’s when you got to use your brain and also use the internet to see what this particular vehicle has a problem with, because we know it’s a transmission problem because P0730 is a
gear ratio incorrect inside the transmission but we don’t know what exactly is causing this code, now this particular code, correct gear ratio, it could be a whole bunch of different things sometimes it’s as small of a thing as the fluid is dirty or the filters clogged up,
but from my experience with many makes and models, when you get an incorrect gear ratio code, especially with ones that are known for having problems, it means that the transmission itself is going out and it needs a full rebuild.
Nowadays with modern complex automatic transmission, you’re talking about thousands and thousands and thousands of dollars, and from my research, one out of every three automatic transmissions in a modern car that’s rebuilt at one of these transmission shops, isn’t fixed right the first time, it has to be done over and sometimes even over again, so it’s something that most people don’t want to get involved with, so let’s say it’s running halfway decently, maybe shifts a little bit weird here and there, well at least with this code reader, we could tell there is a transmission problem and if you have a mechanic check your fluid, which you can’t check yourself anymore because they don’t have dipsticks, and it’s not low on fluid and you can’t find other problems with the scan tool, it’s probably a good idea to just get rid of your vehicle rather than spend all that money fixing the transmission, i hope you find this helpful if you have any question just give us a call at Boise Transmission Repair here in Boise Idaho and we will do our best to get your vehicle back on the road.
