DIY car diagnosis may seem like an impossible task, but it would make more sense to look at it in terms of your own body. If your stomach, for instance, begins to hurt without warning, you will most probably start thinking of the last thing you ate in order to figure out why you’re having the pain. A similar type of thinking goes into diagnosing cars. The moment you start noticing something out of the ordinary, it’s time to start considering the problem and finding a way to fix it.

Mechanical auto problems, as opposed to electrical auto problems, are usually coupled with distinct sounds and sensations that are key indicators that something isn’t functioning the way it was designed to. For transmissions, it takes a lot of use over the years, and after a while, they’re bound to start having some problems. Transmission repairs can be expensive, so it’s worthwhile to pay attention to anything that seems unusual.

If you think you may be having some car trouble or if you’re just looking to learn more about potential transmission problems, check out these 10 signs of transmission trouble and stay one step ahead of your car.
For those who may not know, there are three types of transmission; the manual, automatic and triptronic which combines manual and automatic but works more as automatic since they don’t use physical clutches. But the prominent first two will be the concentration of this discourse.

1: Lack of Response

Transmissions are designed to go into the correct gear every time they are engaged, so when they hesitate or refuse to go, it’s a sure sign there’s something wrong. With manual transmission problems, you may notice after shifting into a gear that the car’s engine will rev up, but the car won’t be moving as quickly as the engine is running. In this case, a worn-out clutch or more serious transmission problem may be occurring.
Automatic transmissions have the same lack-of-response problem, but will usually manifest the issue while engaging the “Park” or “Drive” selection. The car should shift quickly into either of these modes, but if your transmission hesitates to go into either one, then it’s likely there’s an issue with the transmission.

2: Whining, Clunking and Humming

It’s difficult to nail down exactly how your car may sound if there’s transmission trouble, but one thing’s pretty certain, you’ll probably get a that-doesn’t-sound-right feeling when you hear it. Every car is built differently, so the sounds they produce can vary greatly, but if you have an automatic transmission, there’s a good chance you may hear a whining, humming or even a slight buzzing sound.

With manual transmissions, the sounds will usually come across as a bit more abrupt and mechanical sounding. If you shift gears and hear a clunking sound, then you definitely need to have it checked out by a professional. But a clunking sound from underneath your vehicle may not always point to a transmission problem. Your constant velocity joints (CV joints), or even your differential may be the culprit.

The sounds you hear may happen from time to time at first, but if you neglect the noises, they’ll occur more frequently as time goes on.

3: Grinding or Shaking

Depending on whether you have a manual or automatic transmission, your car may respond differently when your transmission isn’t working correctly. As noted in a previous section, with a manual transmission, a common sign of trouble is a grinding sound or feeling when you shift into a new gear. If you fully engage the clutch, shift and then hear a grinding sound, you may have a worn clutch or you may just need to have it adjusted. Or perhaps one or more of your transmission’s gear synchronizers, or synchros, is worn out or damaged. Grinding gears can be caused by a number of different factors.

For automatic transmissions problems, you’ll most likely feel the car shimmy into each gear rather than the typical almost unnoticeable shifts, or the transmission will make a jarring transition into the next gear. Both are signs that your transmission needs attention. If you notice anything other than a smooth transition between gears, then you might need to have your automatic transmission looked at for adjustments or repair.

But feeling transmission problems aren’t the only way to use your senses. Go on to the next page to see what sounds you should be listening for as well.

4: Check Engine Light

The check engine light can be a great early indicator that something is starting to go wrong with your transmission. The check engine light can come on for any number of reasons not related to your gear as well, but don’t overlook this clear warning sign.

In newer cars there are sensors throughout the engine that pick up irregularities in the engine and notify the computer that there’s something wrong in a particular area. In the case of transmissions, these sensors can pick up vibrations and early problems that you may not even be able to feel or see. If you want to know if your check engine light is telling you about a transmission problem, you can purchase a diagnostic scan tool that you plug into your car underneath the driver’s side of the instrument panel. The scan tool will display a code that corresponds to the area of the vehicle causing the fault. If the code tells you there’s a transmission problem, well, that’s a good time to see your mechanic.

third on the block

Op

Pls I need your help o. Since I bought my car Nissan quest 2000 mode in 2014 I have not changed the Transmission oil,Brake oil, Engine oil even any of the brake pads . though I have chsnged the engine oil so many times eventhough. I have not exceeded 1500 since the day we ship it to Nigeria. Except the Service engine soon that do come out once in a while.

Is there any advice u can give me about the car ?

Thank u Sir

This is really a good info.

When is the right time to change transmission fluid?

Most of us here no get car now

If you in kwara state (UK used) I phone 6 (16gig) for sale @ 117k check my Signature for my contact or you come to our shop @ challenge in ilorin

Also check your car when you see oil drop underneath the car in the morning. It may come from the gearbox/ transmission area of the car

Nice one op, is good to always take note of little changes in ur car. Happened to me recently when I had issues with my gear, unfortunately sef na on top one bridge like dat d thing developed fault. The mechanic had to tell me later dat it would av given me signs just dat I didn't notice. Like I said b4, Nice one Op!

That triptronic transmission system, I haven't seen it before. Would like to see how it works.

the transmission oil Is considered as life oil. Ur brake fluid u don't need to change that as well. If the fluid goes down that means ur pads are wearing off. By the time u change the pads. The Piston on ur callipers will be returned to it's normal position then the brake fluid will shoot bck to maximum level.

each time my car is changes gear, there is always this violent/ sudde surge. this has been on for a while now. don't know if it is normal consider it started after I changed gear oil

Nice

Whats your take on this?


Lalasticlala

AutoReportNG, thanks for the information. I'm having issues with my Toyota Corolla 2005, 1.8L auto transmission engine. I didnt experience any of the signs you mentioned here. That day, I drove the car to work and it moved on smoothly with normal transmission only for it to refuse to transmit beyond gear three while driving back home. I changed from transmission oil oil but it didn't resolve the problem.

We also cleaned the gearbox sensor under the car (bottom plate), check all electrical connections and wiring all to no avail until I was referred to guy that they said he's a specialist.

There, the guy said he was going to drop the gearbox and it might take 3-5 days for him to get my car ready so I left the car with him. The guy later called me that same day that he's fixed my car, according to him, the problem was from the gearbox cover which he got another one to replace.

The car was fine after the 'replacement' and I used it for about 7 months both within the town on a long distances as well but the problem later now resurfaced. It's not engaging in gear three and above. It starts fine from gear one to two an it stops there, it then the engine begins to high, the rpm.

Now, the guy is telling me the problem now is the clutch fibres that he'll this time need to drop the gearbox to replace the fibres....

I'm not quite convinced based on the previous experience...what do you suggest?

According to him, it cost me around 40k to fix it while it cost around 100k to replace the whole gearbox.

Meanwhile, I contacted two other mechanics and they both said it's the fibres.

.

Jerking problem sometimes can be caused by weak engine mount (engine seat)

It is a 2000 Infiniti G20 (Nissan Primera, if you like).

The gear does not pick once I engage the gear in D after a long cold-time, eg, first drive in the morning. It usually takes between 1 to 2 minutes before it responds. But once the car picks, it works fine for the rest of the time, except when it is packed again for long.

I am trying to troubleshoot. Any help please.

Many things could cause that, like plugs, coil, or even fuel nuzzles.

It might have nothing to do with gear box. Contact a good technician or you can reach on email for other advice. goshen7autoparts@yahoo.com
