Why Won’t My Transmission Work In 1st?

Ken,

I’ve got a 97 Honda Accord.  It was having a hard time shifting in and out of 1st gear, so I had the transmission redone, but still seem to be having the same issue.  Do you have any idea what the problem could be?

-Andy P., CA

Andy,

If the transmission was redone properly, and you’re still having the same issue, then I think you might be dealing with a faulty transmission sensor.  If the sensor is off, it will try shifting gears at the wrong time, which could be causing your problems.  It’s entirely possible that the transmission didn’t need to be redone in the first place, so if I were you, I’d talk to the mechanic and see if they can’t cut you a deal since they charged you for a rebuild when it wasn’t necessary.

Why Won’t My Car Move?

Ken,

Everything about the engine seems fine.  It starts great, and runs perfectly, the only problem is that it doesn’t move when I shift into drive and press the accelerator.  What could be wrong?

-Fern F., PA

Fern,

From the sound of it, this is almost certainly a transmission problem.  The transmission is what transfers the work of the engine to the wheels.  If the engine really seems to be running fine, I think the only likely solution is a bad transmission.

Replacing the transmission is a big deal and will likely cost you a lot of money, but you should get the car checked out by a mechanic anyway in case there’s an easy fix.

Why Is My Transmission Overheating?

Ken,

I keep getting a flashing light saying my transmission is overheating, but the car still seems to be running fine.  Is this something I should worry about?

Evan A., FL

Evan,

Whenever you get an error light on your car, you should pay attention to it.  In my experience, an overheated transmission is usually just caused by a blockage in the cooling system.  Check the system for any restrictions, and if everything looks clear, you might want to consider having your radiator replaced.

There is also a slight possibility that your transmission itself is in pretty bad shape, but I would have the cooling system checked first since it is a more likely problem, and costs less to replace.

Why Does My Engine Whine In Low Gears?

Ken,

I’ve got a Peugeot, and it makes a whining noise in the first 3 gears.  When I get to 4th and 5th gears, the whining goes away.  What could be causing this?

-Derek A., ID

Derek,

Peugeot transmissions have been known to have these problems.  The issue is usually with the gearbox.

The reason the 4th and 5th gears don’t whine is that they use a different gear path and so function with different parts than the first 3 gears.  I would suggest taking the transmission to a shop to be inspected.

If the whining continues, it could lead to further issues, so I would recommend having the problem addressed soon.  Have the mechanic check out the input bearing and drive shaft in particular.

Why Won’t My Transmission Change Gears?

Ken,

Lately, my transmission has been acting up.  It will switch fine from neutral to first gear, but when I accelerate, it doesn’t shift gears and revs up to really high RPMs around 20 mph.  The car has 200,000+ miles on it, so I’m worried this might be a big problem.  Any thoughts?

-Britt C., CT

Britt,

I hate to say it, but this sounds like a pretty big issue.  At the very least, the transmission will need to be rebuilt, but with an engine that old, it may make more sense to just replace the transmission.

One thing you may want to check is if there is a manual option on your shifter.  Some cars give drivers the ability to change gears themselves, so if this is a new-to-you car, you might want to check out that possibility.

Why Is My Transmission Rough?

Ken,

I replaced the transmission in my 2001 Volvo.  It’s a new transmission, but it seems to be off.  Sometimes it’ll change gears just fine, but other times the shift is really rough.  Any idea what’s going on?

-David W., OR

David,

My best guess is that the control module needs to be reprogrammed.  If your engine was running on a worn transmission for a long time, the computer still thinks it’s dealing with a worn transmission.  If you take the car to a dealer, they should be able to reset the control module for you.

The reason why if feels rough at times is most likely because the old transmission slipped in that gear.  The control module is trying to overcompensate by gripping the clutch too tightly.  I would get this fixed as soon as possible because running the engine like this can cause some damage.

Do I Need To Get My Transmission Rebuilt?

Ken,

When my car is completely stopped and I press the accelerator, sometimes nothing happens. The engine will rev up, but the car won’t move. One mechanic told me this it a problem with the transmission, but I wanted to make sure before I spent a bunch of money on it.

-Kris B, MN

Kris,

While this could be a transmission issue, I would first check the throttle position sensor, throttle body, and accelerator position sensor. If and only if all of these turn out to be fine should you go head and get the transmission rebuilt.

Rebuilding transmissions can be a very expensive process, so it’s good to make sure it’s necessary before committing.

Why Won’t My Manual Transmission Shift Out of Gear?

Dear Ken, my car has a manual transmission. It will not shift out of gear. It appears to be stuck in 2nd gear.

The clutch pedal feels and works fine.

The car has a 2.4L engine and with only 74k miles on it.

Could it be the transmission linkage? Or what else could it be?

Thanks.

- Eric S., ID

Dear Eric, yes it could be the linkage.

An experienced mechanic will be able to check this idea out and properly adjust the linkage.

Linkage becomes slightly bent and / or loose. This prevents the clutch fully disengaging and allowing the shift out of or into gear.

Hope this helps.

Why is My Transmission Difficult to Shift?

Dear Ken, the used 1998 Oldsmobile Intrigue I found on Cars for a Grand has a gear shift that is very hard to shift.

Sometimes the transmission won’t shift into gear at all.

Could this be the linkage or should I replace the gearshift?

- Greg U., ND

Dear Greg, transmissions — both automatic and manual — require that the shift linkage be adjusted properly.

This means that unless the linkage pushes with the correct directionality and pushes far enough, the transmission will not go into gear.

Also, unless the linkage is adjusted properly, it may not be shifting completely out of gear. It must shift and be clearly out of a previous gear before it will be able to extend into another gear.

Check the linkage for excess play. Check the linkage for bent levers and lost clips. Be certain that the linkage is pulling the transmission out of gear before it attempts to push it in another gear position.

Hope this helps.

How Do I Park Uphill to Avoid Damaging Transmission?

Dear Ken, I just rented a place with parking spot that’s on a slope. How do I park the used car I just bought from Cars for a Grand in a such a way that it doesn’t mess up my transmission?

- Terrence R., MT

Dear Terrence,

To prevent long-duration and excessively-heavy strains on your automatic transmission’s locking mechanism do as follows:

Uphill, park a few inches from the curb. Turn the front wheels outward and, while braking, allow the car to slowly roll back a few inches until it gently bumps and rests against the curb. Then put the transmission into park if it is an automatic and reverse if it is a manual shift transmission.

Downhill, also park a few inches from the curb, turn the wheels inward, and while applying the brakes, allow the car to slowly roll into the curb. Then put the transmission into park if it is an automatic and reverse if it is a manual shift transmission.

Hope this helps.
