5 causes of manual transmission shifting hard especially from 1st to 2nd

A vehicle with a manual transmission means you have to manually change gears by shifting the transmission. Although this can be very fuel economical and require less maintenance for the vehicle, there are situations that could arise where your manual transmission shifting becomes more difficult. Sometimes it will get to the point where you can even change gears at all. Once that happens, the vehicle will mine as well be undrivable. You will have to get it towed to the nearest auto mechanic or dealership to have the transmission checked.

Top 5 Causes of Difficult Manual Transmission Shifting

Hard shifting with manual transmission usually has to do with a problem in the gear system or with the clutch. Either one of the parts of the gear system is damaged or it is just completely worn out from too much use. Below are the top 5 causes of a manual transmission being hard to shift.

  1. Damaged Master Cylinder – The clutch system is comprised of a variety of components. There is the clutch master cylinder, the clutch cover, the release cylinder, the release fork, and the release bearing. If any one of these components is damaged, particularly the release cylinder or the clutch master cylinder, then you will have difficulty shifting gears.
  2. Damaged Gears – There are lots of gears in a manual transmission system. There is 1st gear, 2nd gear, 3rd gear, 4th, gear, 5th gear, reverse gear, and counter gear. There is also a hub gear which goes between the 1st gear and 2nd gear, and the 3rd gear and 4th If any one of these gears becomes damaged or worn out, then you will have trouble shifting them.
  3. Damaged Hub Sleeve – When the hub gear bridges between the main gears, the hub sleeve is what actually engages these gears. It can move either right or left, depending on where the gear has shifted. The sleeve helps ensure the hub gear teeth synchronize with the synchronizer ring’s teeth. If the hub sleeve is worn or damaged, then synchronization won’t be there. This will cause shifting problems and difficulties.
  4. Damaged Synchronizer Ring – The synchronizer ring has lots of small teeth which allow the hub sleeve to easily engage it, so it can go into one of the main gears. If there is damage or wear to the synchronizer ring, then it won’t be able to engage with the hub sleeve. As a result, you will have shifting issues.
  5. Low Level of Gear Oil – It is important to change your transmission oil every once in a while. If you don’t change it or if you have a transmission oil leak, then your gears won’t be getting enough oil to lubricate them. This will not only make it harder for you to shift gears, but your transmission will become damaged as a result. Furthermore, you will hear lots of weird noises coming from it too.

How to Fix

Where the transmission is concerned, nothing is going to be an easy or affordable fix. If you have low transmission oil, then that will be the most affordable problem to fix. But if there is a leak, then you will have to seal the hole or replace the fluid lines. This will still be more affordable than having to repair or replace the entire transmission. One thing is for sure though, if you wait too long to fix whatever is causing the shifting problems, then your transmission will become permanently damaged. Don’t let this happen to you. Get your vehicle to the nearest mechanic as soon as you experience shifting problems.
