Welcome to part 2 of our Top 10 most common transmission problems, where we run down top faults 6 through 10. As with the first part, there is no specific order to the faults, in either frequency or severity, but keep an eye out for them and give us a call as soon as anything catches your concern! IF you missed part one, you can find it here. So let’s get right back into it with the first entry:
6 – Shaking and/or Grinding
When your car is running smoothly that exactly what it does – runs smoothly. There are (and should be) no grinding noises when you change gear, no shaking when you have a gear engaged, and you shouldn’t feel any resistance on the stick as you change gear either. The most common fault causing the grinding and shaking is a worn clutch plate, although it could be down to a number of other factors, including the worn out or damaged synchronizes. You will most likely feel the resistance before the grinding noises start, so lend an ear to spot the signs as soon as they begin. As with most other faults in this list, they are unlikely to cause a complete roadside failure, but catching them early means they are less likely to damage other components in your transmission.
7 – Noise
Now you might like your car to make noise, a hearty roar when you rev the engine – although this is unlikely if the engine is a 1.2l petrol or just about anything diesel! So if you aren’t driving a 5.0l Mustang, then noise is probably an indication that something might be a bit wrong somewhere – particularly if this occurs in neutral. A noisy neutral transmission, listen out for a bump sound, can be a quick, inexpensive fix, most likely caused by a low fluid level that can be topped up with ease – however it could also be a more serious issue requiring professional assistance. Worn out parts, like bearings or gear teeth – if the fluid top up does not help, give us a call.
8 – Clutch is dragging
Nothing to do with the pedal getting stuck on the floor mat, instead this fault deals with your clutch plate failing to disengage so it is still spinning with the engine, so it is nearly impossible to change gear. When you do eventually change gear it will be accompanied by a chorus of grinding noises described above! As terminally expensive as this sounds, it can sometimes be fixed by simply removing the slack from the pedal – tightening the cable so that the clutch plate will disengage properly.
9- Slipping out of gear
When you change gear in your car it is designed to stay in that gear until you make a change – whether to neutral at a stop or into another gear. What you don’t want is the gear to pop out while engaged, as this is a clear safety hazard. You are driving along, 60mph on the motorway and your car pops into neutral. As your foot has likely stayed on the accelerator then the revs shoot up, there could be a moment of panic and in that moment you have no engine braking available as you are in neutral. If your car is slipping out of gear come and see us as soon as possible.
10 – Check engine light
To round out our top ten list we visit the catchall Check Engine light – the good old Check Engine light, entirely non-specific in its warning, is it something that will fail in the next ten miles? Is it something innocuous that just needs sorting before your next MOT? Who knows?! Until you get your car checked out it is impossible to tell – even with a ‘guaranteed to work’ diagnostic tool you bought of eBay for less than £30. The only way to set your mind at ease is to visit a professional (like A1 Clutches) and have it checked out properly.
So that finishes off our top ten things to look out for in your car regarding your transmission. This guide was not intended to cause alarm or scaremonger; instead it is just a list of things that can go wrong so that if you notice anything a little out of the ordinary you can act fast to make sure minimal damage is done – both to your car and your wallet or purse!
