Reverse not working , though other gears still do.

Reverse gear is gone. The car still goes into other gears.
Experienced mechanics share their insights in answering this question :
Assuming your vehicle has a manual transmission, it is possible that your shift cable bushings could be severely worn causing the reverse gear not to engage as this is a common problem on Dodge vehicles. If the shift cable bushings are good you may have an internal issue within your transmission and replacement or overhauling the transmission may be necessary. I would recommend having your vehicle’s gears inspected by a technician to diagnose the issue.

Just as you learned what happens with low transmission fluid, dirty fluid, or a clogged filter can cause similar transmission troubles and create a car that won`t back up in reverse. Improper lubrication from old fluid or debris in contaminated fluid will affect how the transmission shifts into reverse or other gear.
However, a defective speed sensor is viable by an illuminated warning light on the dashboard, signalling that it`s time to repair or replace the speed sensor. These are the major causes that hamper the transmission system, due to which the car won`t go in reverse sometimes.
The first thing to look at is the transmission selector switch. If it`s not working, the computer won`t receive the signal that says it needs to go in reverse. Over time, corrosion can disrupt this part. For a quick fix, try putting the car from park into reverse several times slowly.
The linkage between the shifter and the transmission range selector may be binding or broken and not allowing a full range of movement at the transmission. The linkage connects to the transmission under the vehicle so it must be lifted or the mechanic may have to crawl under to check out the linkage.
But if the solenoid malfunctions mechanically, no reverse or delayed and slipping reverse may occur.
Problems Reversing – One common problem that can happen with a clogged filter is difficulty moving in reverse. The lack of fluid flowing through the transmission can cause the reverse gear to lock. This may prevent the car from going in reverse altogether, or it may cause it to hesitate before launching into reverse.
Transmission Range Sensor (TR)/ Transmission Position Sensor

The PCM uses this information to control which gears of the transmission to enable or disable. When the TR sensor fails it can cause wrong gear starts, no upshifts, or what feels like a falling-out-of-gear condition.

Occasionally, these sensors can fail or become faulty working intermittently sending inaccurate signals to the ECU. In your case it may be possible that the transmission is receiving a faulty signal from the ABS system.
The switch prevents the engine from starting when not in park or neutral. This eleiminates the risk of starting an automatic car in drive or reverse mode. Located in the linkage or the transmission box, a bad neutral safety switch can cause irreversible damage to your car`s engine and transmission.
A failing transmission position sensor may no longer send the right signals to the Powertrain Control Module, or PCM. Without signals from the position sensor, the PCM will no longer know when to shift the transmission`s gears out of park into a moving gear. Transmission shifts into the wrong gear.
If you look at the solenoid application chart in Figure 1, you`ll find that only shift solenoid F (SSF) is on in the reverse position. SSF is on the secondary valve body and controls the position of the 4-5 shift valve.
The reverse flow solenoid has a third port that redirects the fluid to the master cylinder that would be going to the trailer brakes. When the reverse lights on the tow vehicle activate the solenoid, the valve inside the solenoid redirects the brake fluid to return to the master cylinder.
Once the pump inlets and outlets are blocked, the transmission will begin to slip. You will notice that after engaging the gears, they will have trouble staying in one or more positions. For example, if you place the shift lever to the third position, it will go back to gear two or even jump to the fourth gear.

Ignition barrel – If the ignition barrel is faulty it can cause the transmission to get stuck in park. Faulty shifter mechanism – If the shifter or the shift bushes are worn it can make the transmission hard to shift into gear.

The manual and how to fix it….5th gear is not working I went by a machanic n the gears are still not going in well
ANSWER : Hello. If you still are not getting 5th gear then you have an issue within the transmission. If the transmission is brand new then it should be taken back to where you purchased it from. If this was a used transmission then it is faulty.

The transmission on your Mazda B2000 has a history of having internal synchronizer issues that cause this to occur. Completely rebuilding the transmission is what it will need. In some cases the issue is in the shifter assembly itself so that should be removed and checked to see if it is binding internally.

If this is something that you need to have checked out, consider YourMechanic, as a certified mechanic can come to your home or office to diagnose your shifting issue firsthand.

Car struggles to go into the reverse gear and makes a clunking noise
ANSWER : Other consumers report the type of issue you have with various years and models of BMW but the reports are model specific. If you do a Google search ("difficulty getting reverse BMW "model, year") for your car, you can try the various strategies that I see published. I would suggest one, but I do not know which model you have. If none of those work out for you, that would point to there being a mechanical fault with the reverse synchronizer and related assembly in the transmission. That latter possibility being strongest of course if this difficulty in shifting is a "new" issue that you are experiencing. If you need help diagnosing the shifting issue, a certified professional from YourMechanic can come to your car’s location to inspect the vehicle and advise on the repair.

New Aftermarket clutch works well and gets into gears smoothly but 1st and reverse gears makes my engine shutter like no other.
ANSWER : The shuddering you feel may be a warped or contaminated pressure plate/flywheel. I normally send the flywheel to a machine shop to have it resurfaced when I install a new clutch. This helps prevent the shuddering you described. Contamination from oil or grease can also cause that feeling, but not as severe. You don’t really need to break in a clutch, but sometimes they will grab a bit better after a while.

If you’d like to have this looked at, consider YourMechanic, as a certified technician can diagnose the shuddering you’re experiencing and fix it from there. Best of luck.

I have a 2003 Ford Expedition 5.4 liter my reverse just stopped working all of my other gears work fine including Overdrive dude w
ANSWER : Even with the fluid appearing to be in good condition, something inside the transmission may have failed. The valve body is comprised of multiple passages of different length and diameter to control fluid pressure to each gear. If the reverse gear fluid passage has become blocked, this will effect fluid pressure to reverse, possible preventing it from engaging. The reverse gear set / clutch pack can also be the cause. It may be best to have a local transmission specialist inspect the transmission.

Loose gearbox that won’t find 2nd or 5th gear, sometimes hard to differentiate between 1st and 3rd.
ANSWER : There are a couple of possibilities. The first thing that comes to mind is of course the shifter itself. There is a nylon ball and socket joint at the base of the gearshift lever that sometimes falls apart, making the feel of the shifter very vague. Additionally, there are links to the transmission shift linkage that involve nylon bushings and joints that can fall apart. Both problems are very common on your car. The other less common possibility is that you have a bad motor mount that is allowing the transmission to move around too much when you try to shift gears. either way, it’s not a big deal to fix, and probably won’t require expensive transmission work. If you contact Your Mechanic, they can send a technician to your home or office to check out you shifting issue and let you know what repairs it will take to correct it.

The car doesn’t shift into first gear while it works fine in reverse
ANSWER : The problem could be that the internal transmission pump is weak, or the transmission clutch seals are leaking. It sounds like the transmission will need an overhaul.

I recommend having a transmission mechanic test the pressures and diagnose the problems to verify whether you need an overhaul with a new torque convertor.

neon manual 5 speed drives great but will not shift into 4th gear while driving. All other gears work fine 4th works when off
ANSWER : Hi there. Most of the time when a manual transmission is hard to shift into an individual gear, it’s caused by the linkage being ’twisted’ or not aligned correctly. However, it is also possible that internal damage has occurred inside your transmission that is causing this problem. In most cases, a clutch issue would cause shifting issues on all gears. Before you spend money on repairs, it’s probably a better idea to have a professional mechanic complete a car is hard to shift inspection, so they can isolate the source of this problem and provide you with the correct repair advice.

My manual car won’t go into gear, it turns on and the clutch goes down perfectly fine. It happened after my gears grinded, the car
ANSWER : If the clutch mechanism is releasing properly, and the shift linkage is not malfunctioning, your transmission will have to be removed from the vehicle and inspected. Once a transmission has been removed from a vehicle, if the problem is a broken or worn part or parts, and the transmission has 100,000 miles or more, the most cost effective approach is to just simply rebuild the whole transmission. There are transmission rebuild kits that are sold just for this purpose. Rebuilding a transmission is no big deal and is indeed easier in many respects than rebuilding an engine. You can rebuild your transmission right in your own garage. You can NOT rebuild an engine in your own garage due to the highly specialized, and extremely costly, machine shop equipment required. Occasionally, mobile mechanics will take on a transmission rebuild job especially as once the mechanic removes the transmission from the vehicle, it is just simply a modular unit that can be easily transported to a mechanic’s shop and rebuilt right there and then returned to your vehicle.
