Trying to find out the speed of my transmission on my truck.

Experienced mechanics share their insights in answering this question :
The speed of a transmission will go as fast as the speedometer is registered for in your vehicle. The speedometer is regulated to monitor the vehicle’s speed in a safe manner. This is why it has a limit on the gauge and the computer will shut down the engine temporarily to keep the vehicle from over-speeding.

How to Identify and Fix Common car Problems ?

Common signs include harsh or improper shifting, cruise control not working, and the Check Engine Light coming on.
You can find your vehicle`s transmission on your window sticker. It will be listed under Vehicle Description on top of the window sticker.
A wheel speed sensor (WSS) or vehicle speed sensor (VSS) is a type of tachometer.
Typically, two sensors communicate the transmission data to the vehicle`s powertrain control module. The first sensor, referred to as the input sensor, monitors the speed of the transmission`s input shaft. The second sensor is the output sensor, which monitors the output shaft speed.
The output speed sensor is also known as the vehicle speed sensor in a vehicle. It transmits a signal to the transmission control unit, informing it of the vehicle`s speed. Failure of the speed sensor is a common reason for taking the car to the mechanic.
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. When the TR sensor fails it can cause wrong gear starts, no upshifts, or what feels like a falling-out-of-gear condition.
Typical data transmission speeds are one to 100 megabits per second.
Therefore, a speed sensor failure will have a direct impact on the automatic transmission operation. If your vehicle has a failed speed sensor then you might notice signs such as hard shifting, limited gear operation, delayed shifting and rough shifts.
A part of the Electronic Control Unit (ECU), the Transmission Control Unit covers everything related to the transmission of a vehicle. It ensures smooth gear shifts and optimal fuel economy and performance.
Unplugging the TCM will eliminate the possibility of damaging the module during diagnosis and/or repair. The control module may be damaged when the metal case contacts battery voltage.
A speed sensor is a type of position sensor which is used to measure rotational speed. They are present in various types of commercial and motorsport vehicles. Like many devices, a speed sensor is an integral part of onboard systems.
What does a Vehicle Speed Sensor do? Vehicle Speed Sensors measure wheel speeds and provide this information to the vehicles ECU (Electronic Control Unit). The ECU calculates ignition timing, transmission shift points, and air/fuel ratios for the vehicle.
MAP – The Manifold Absolute Pressure sensor creates a signal based on vacuum levels in the intake manifold, which indicates engine load. A faulty MAP sensor can cause late, harsh shifts, early / soft shifts, or even prevent the transmission from shifting at all.
It`s also common that a problem with these sensors can impact the shift timing, extending the interval between transmission shifts. An automatic transmission is hydraulically controlled and designed to operate smooth.
The ECM doesn`t control the transmission on a stick shift, so if you`re having problems with your five-speed, it`s the transmission. If you`ve done numerous repairs on the transmission and replaced your automatic transmission fluid and you`re still having problems, the ECM could be at the root of your problems.
The gearbox in a car is a component that enables the torque to change or changes the rpm speed of the engine. The input shaft connects to the engine on one side, and the gearbox on the other.
In general, it`s best to shift up around 3,000 RPMs (3 on your tachometer) and down at 1,000 RPMs (1). Low RPMs are best for efficiency, but every vehicle is different. If you shift any lower than 1.5, you`re likely to stall out.
A more powerful engine can accelerate quicker and reach higher speeds, however, more fuel will need to be pumped into its cylinders in order to create this power, which can make them less eco-friendly.
A download speed of 150Mbps allows you to stream ultra-HD video on 6 devices at the same time, or download a HD movie in 4 minutes. If you`re using a broadband internet connection with download speeds of 150Mbps, you can comfortably stream ultra-HD quality video on up to 6 devices at the same time.
This includes speed sensors that tell your transmission how and when to change gears. If your speed sensor is sending incorrect data, it can lead to hard shifting and other drivability problems.
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.
However, calibration can also be required as a byproduct of common car service work such as windshield replacement, suspension repair or wheel alignment. Failure to calibrate a sensor when necessary can result in faulty information that will cause ADAS to operate improperly or not at all.
Calibration of the speed sensor should be performed at least once a year Check that the radar unit is securely affixed to the vehicle frame and that the correct angle between the unit and the ground.

I parked my truck for 5-10 mins. Tried to turn it on, now it wont start, called a tow tow truck 15-20mins later my truck turned on
ANSWER : It is very likely that you have a powertrain control module failure. This can happen often on many GM vehicles. I would recommend having the powertrain control module tested and replaced as necessary in order to resolve this issue. After the powertrain control module is replaced, a reflash procedure will be required so that the vehicle can relearn all of its primary engine data. Once the reflash is completed, your vehicle should no longer have this issue.

1988 Chevy C60 dump truck. Grinding noise from transmission while in gear
ANSWER : You might want to remove both PTOs first. They may be seized or have bad bearings. You may also have burned out the input bearings. The transmission will need to be removed and torn down to see what the damage is to the bearings, gears and synchronizers. I recommend finding a reputable transmission shop to do the job.

5r55e transmission issue
ANSWER : Hello. Transmission shifting problems can be caused by a wide variety of issues. A few common causes are issues with the fluid, torque converter. Automatic transmission operate using fluid pressure. If the transmission fluid is dirty or contaminated, or the pressure is compromised, perhaps due to a leak, it can cause the transmission to malfunction. Another possible cause could be with the vehicle’s torque converter, or clutch packs, inside of the transmission. These components are what convert the fluid pressure into torque to propel the vehicle and can cause shifting problems if there is any issues. As these are internal components, the transmission would have to be removed and disassembled to service or replace them. Another possible cause is faulty shift solenoids. The shift solenoids are the components that engage the shift points and gears, if they go out they can cause the transmission to experience shifting problems. I would recommend having a professional technician, such as one from YourMechanic, come to your location to diagnose the cause of your transmission shifting issues.

just replaced radiator on 1996 Chevrolet automatic truck drove for 2 days very short distances was making strange noises but all g
ANSWER : It sounds like the radiator replacement did not go according to plan. The transmission fluid is cooled through the radiator as well as the coolant. Often times there are small plastic caps that are inserted into the transmission line connections on a new radiator. If the transmission lines were installed over these plastic caps, the transmission fluid would have been restricted from entering the radiator. This would have caused a pressure build up that likely resulted in the leak you have. I would recommend determining if this plastic cap is still on the radiator first. If so, remove the cap and top off the transmission fluid to resolve this issue.

2003 jeep liberty stuck in reverse, shifter is stuck…but crawling under and trying to manually shift from transmission stuck
ANSWER : Hi there. Based on what you have written above, it is highly probable that the inner linkage has come loose or there is an obstruction within the inner gear set that is causing your problem. Unfortunately, this typically requires dropping the transmission and repair or inspection from the inside. This is not a service our mobile mechanics are equipped to offer, so your best bet is to contact a local transmission specialist for assistance.

Bought a 1999 Chevy Z71 for very cheap. The transmission is out. How should this be fixed?
ANSWER : Hi there. The 4l60e transmission could have two things wrong with it. Either the park arm is not disengaging inside the transmission making the transmission load up but not rotate the drive shaft or the transmission is low on oil. Check the oil on the transmission dip stick and see what the level is. The level must be checked with the engine running. If the oil level is at the full mark, then it is possible that the torque converter may have damaged the pump.

Remove a cooler line and put it into a bucket, and for a brief moment start up the engine and shut it off. If oil sprays out of the cooler line, then the pump is producing pressure. However, if no oil comes out of the cool line, then the pump is not working.

If you need further assistance troubleshooting your transmission, then I recommend having the transmission problem diagnosed by a local expert, such as one from YourMechanic. You will be be able to make a better decision about the car after finding out exactly what’s wrong with it.

I have a 1998 ford ranger(AT) its shifting roughly, when i come to a stop, the truck wants to keep going, and as a result, the truck stalls out.
ANSWER : The torque converter clutch is not releasing as the transmission is shifting. Try pulling the fuse to the torque converter labeled as TCC and see if the symptoms change. If the vehicle stops acting up, then the torque converter clutch solenoid is active and not releasing. If the symptoms are the same, then the torque converter clutch is melted and needs replaced (torque converter replacement). If you need further assistance with your transmission shifting hash and stalling, then seek out a professional, such as one from Your Mechanic, to help you.
