5 Causes of a Hard to Shift Manual Transmission (Especially 1st to 2nd)

A vehicle with a manual transmission means you have to manually change gears by shifting the transmission. Although this can offer a fun and rewarding experience for the driver 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’t even change gears at all. Once that happens, the vehicle will might as well be undrivable. You will have to get it towed to the nearest auto mechanic or dealership to have the transmission checked out

Top 5 Reasons a Manual Transmission is Hard to Shift

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 five of the most common causes of a manual transmission being hard to shift gears.

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 sometimes a 6th gear. There is also a hub gear which goes between 1st gear and 2nd gear, and then 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 (or synchronizer hub) 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 difficulties and other problems.

4) Damaged Synchronizer Ring

The synchronizer ring has a lot 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 Transmission Fluid or Gear Oil

It is important to flush and change your transmission fluid (or gear oil) every once in a while. If you have signs of burnt transmission fluid and you don’t change it or if you have a transmission fluid leak, then your gears won’t be getting the lubrication they need.

Low transmission fluid is not something to be ignored. This will not only make it harder for you to shift gears, but your transmission will get damaged as a result. Furthermore, you will hear lots of strange 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 fluid or gear 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 can become permanently damaged. Don’t let this happen to you. Get your vehicle to the nearest mechanic as soon as you experience shifting problems.

  1. My car has gears are hard to shift between 1 and 2nd gear, early in the morning,I have changed the clutch,the master cylinder even the gear cables,now I don’t know what to do. It’s a GWM Florid 2011 model.

    • same like me. hard to shift early morning. after 10 to 15min drive then ok. but still can feel the rough and stiff a bit while changing. any clue?

      • That’s fairly normal behavior for a manual transmission. Gear oil is thicker when cold, which means each shift takes a bit more effort and won’t feel as smooth. This is especially true in the winter time with colder temperatures. It’s nicer on the synchros if you try not to shift too aggressively until the transmission has warmed up (about 10-15 minutes). You can drive normally, just don’t force anything. If your gears are grinding, this may be worth looking into, but otherwise you’re probably fine.

  2. I have trouble every once in a while getting from 1st to 2nd…. it literally will not shift to 2nd. Like something is blocking the stick. Most of the time it’s fine but once in a blue, I have to go to 3rd. I go back to first, I wiggle it, play with it, but it just won’t let the stick into the 2nd gear.
    What’s up with that?

  3. Mine is a VW polo vivo, when I start the car it shifts normally but after driving for sometime and I get to a stop sign (after disengaging the current gear – I do not change down when I stop)the gears won’t engage. I need to wiggle it out for a couple of seconds looking for any available gear,after take off I then I shift upwards also using the same technique as some gears will be locked/stiff or loose.

  4. i have the same problem but then the oppsite when the car heats up hard to shift into gear but when cold shift like butter….

    • My truck is grinding a lot and getting harder to shift into reverse. And after driving it a minute it’s getting harder to shift gears. What could this be and is it affordable?

      • Grinding noises are not cheap noises. 🙂 My advice is to figure the problem out as soon as possible to minimize transmission damage.

        If you’re lucky, the gears may be salvageable and the fix could be as simple as topping off the transmission fluid. Check to make sure the transmission has enough gear oil. Check the transfer case too if you have a 4×4 model.
