Hello – I believe you have a failure in the reverse input clutch in the transmission. This could be caused by several components in this clutch, all of which will require removal and disassembly of the transmission to repair. To confirm this diagnosis, I recommend a transmission inspection by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, give you an accurate assessment of damage and cost estimate for repairs.

An automatic transmission that won`t go in reverse is just one symptom of a low transmission fluid level. You may notice fluctuating shifting or an engine that overheats or stalls. Weird things happen when your car`s systems have to work harder than they are supposed to.
On an automatic transmission, leaking internal gaskets, seals or O-rings will keep clutch packs and bands from engaging gearsets — a common cause for the inability to go in reverse. Leave these for your mechanic to fix.
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.
In many cases, delayed shifting of any kind is caused by issues with the transmission`s valve body. Shift solenoid or computer malfunctions can also result in these types of hitches and may require transmission service for correction.
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.
When the transmission is put into Reverse, the small sun gear turns the outer ring gear backwards. For Park, a small toothed parking gear is firmly held by a small latch called a parking pawl, which prevents the output shaft from turning the wheels.
A surefire sign of a failing torque converter is when the vehicle won`t shift into a specific gear at all. If you can`t get it to go into reverse or forward drive won`t engage, then it`s probably something wrong with your torque converter.
Transmission Range Sensor (TR)/ Transmission Position Sensor The Transmission Range Sensor tells the PCM the position of the transmission shifter. The PCM uses this information to control which gears of the transmission to enable or disable.
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.
With engine off and ignition on, check for proper solenoid operation by placing gear shift in reverse. Backup lights should turn on and an audible click should be heard in the solenoid. Make sure backup lights do not engage in any other gear position.
The transmission position sensor is usually screwed onto the side of your car`s transmission. As you move the automatic gear selector from park/neutral to drive or reverse, it detects the changes. It then enables and disables the connection to the starter motor circuit, affecting your car`s ability to start.
A backup light switch screws into the transmission and is triggered when you shift the vehicle into reverse. If the switch is functioning normally, a circuit is completed when the switch is triggered and the white lights in the tail lights will illuminate, indicating to other drivers that you are backing up.
A transmission that does not go into reverse can be caused by a wide variety of different issues, and could be related to the fluid leak you are experiencing. A few common causes for a transmission that will not go into reverse is a faulty transmission solenoid or low fluid.
The job of the transmission filter is to collect excess debris that may otherwise cause damage to the valve body and other internal parts. You may run the risk of damaging the transmission further by driving without the transmission filter.
If your car will not go into reverse, it is an indication that the reverse gear in your transmission has failed. This will prevent the truck from going into reverse. To fix this problem, the transmission will need to be rebuilt or replaced.
If the shifter is on your steering column, then the neutral safety switch will often be located beneath the gear shifter. Some manual vehicles have a similar device located under the clutch pedal.
Modern cars, which have 6 gears, usually have a spring or button, located right below the head of the gear shift, which you have to move upward or press if you want to shift into reverse. Whatever the situation, look for reverse gear on the top of the gear shift, press the clutch and shift into reverse.
This could likely be due to a faulty computer that controls the transmission, a faulty transmission solenoid, or another issue with your transmission. If there is an issue with your solenoid you could be experiencing slipping gears or a transmission that won`t shift into gear properly at all.
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.
Along with gear slippage, low transmission fluid levels can also cause low levels of pressure, which leads to slower engagement when shifting gears. If you notice your transmission takes a second to engage when put into drive or reverse, it could be due to low fluid levels.
