| Gear | Inches per engine revolution | Speed per 1000 RPM |
|---|---|---|
| 5th gear | 28.6 inches | 27.1 mph |
| 6th gear | 42.9 inches | 40.6 mph |
What mph should I be at on 5th gear?

|---|---|
| 2nd Gear | From 5mph to 15mph |
| 3rd Gear | From 15mph to 30mph |
| 4th Gear | From 30mph to 40mph |
| 5th Gear | 40mph upwards |
What causes 5th gear to pop out?
Popping out of gear is a common problem when it comes to manual transmissions. The most common reason a manual transmission would jump out of gear is due to low or contaminated fluid, worn synchronizers inside the transmission, or improperly adjusted shift linkage.
Is it OK to drive in 5th gear?
To answer your question, no it isn’t bad for your car to keep it in as high a gear as you can while still maintaining speed. As long as you are above idle in RPM and your engine isn’t lugging, you aren’t doing any damage.
Is first gear bigger than fifth?
(We’ll go into how all the gears can always be spinning while only one of them is actually delivering power to the drivetrain here in a bit.) First gear is the largest gear, and the gears get progressively smaller as you get to fifth gear. Remember, gear ratios.
When should I use gear 5?
5th, or 6th gear (if you car has it) are termed as ‘overdrive’ gears. An overdrive gear allows your car to cruise at a high speed while maintaining low engine revolutions. You’ll use 5th or 6th gear for highway cruising at speeds of 60 mph to 70 mph and are ideal gears for best fuel economy.
How does a 5 speed gearbox work?
On a five-speed transmission, there’s a collar between the 1st and 2nd gears, between the 3rd and 4th gears, and between the 5th and reverse gear. Whenever you shift a car into a gear, the synchronizer collar shifts over to the moving gear you’re looking to engage.
What does 5th gear do?
5th gear is usually an overdrive gear that allows for economical motoring at freeway speeds but no greater acceleration. Therefore overtaking in 5th gear is not recommended as it takes longer and increases the risk of a head on collision.
Why does a vehicle jump out of gear?
The manual transmission can jump out of gear because of worn mounts or loose linkage. It’s also caused by bad shifter bearings or a weak spring in the shift rail. The worst-case scenario is that something is internally wrong with the transmission, requiring a rebuild or replacement.
Does 5th gear save petrol?
Use gears properly Using your gears properly can also help reduce fuel consumption. Make sure you use higher gears at lower speeds such as 4th gear at 30mph, 5th gear at 40mph and so forth.
What gear is best for 30mph?
Third gear
Third gear is a very flexible gear in modern cars, including diesel cars, and it’s the ideal gear when you need to keep your speed to 30mph or under.
