Drop in power after I heard a pop. Truck makes noise when in gear.
I think something happened to the transmission. The truck is making a whining noise when I put it in gear. While accelerating I felt a large pop or thud, and the vehicle dropped in power, but continued to drive and accelerate.
Experienced mechanics share their insights in answering this question :
Hi there. Many people have experienced the exact same issues with their Tahoe’s that you are having. There are a number of common issues with this transmission that can cause this. It can be a failure of one of the bands in the transmission or it can be a fracture in the sun shell. In either instance the best place to start would be to remove the transmission oil pan and inspect the fluid for debris or metal shavings. Metal is a sure sign of a serious issue that is going to require a rebuild. At that point you would need a certified mechanic to tear down the transmission and rebuild it.
How to Identify and Fix Common car Problems ?

If the sound resembles humming, buzzing, or clunking, you may be experiencing transmission failure. Bad automatic transmissions may emit humming, buzzing, or whining noises while manual transmissions have harsher “clunking” sounds.
A common issue for all types of transmissions, slipping occurs when problems with the transmission fluid happen. For example, transmission fluid issues may arise when the fluid level is low. In addition, a leak or burned or old part can cause the problem to become persistent.
One of the more common Chevy Tahoe transmission problems is the loss of 3rd and/or 4th gears. This occurs because the clutch discs inside the 4L60E 3-4 clutch pack have a tendency to wear out and fail prematurely.
One of the common weak points of a factory 4L60E is the sun shell.
If the gear shift in your car is difficult to get into gears, causes grinding noises, or just won`t move at all, the transmission is dying or has died. An automatic transmission should shift smoothly and noiselessly, so vibrations, changes in performance, or strange sounds, are all indicators of transmission trouble.
Use more clutches and larger gear band servo pistons.
For a greater band-apply capacity of around 18 percent, use larger gear band servo pistons. There`s also the need to use seven clutches (3-4 clutches/drum) including the Raybestos forward, reverse input clutches, and overrun.
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.
Unfortunately, customers have complained about the 2018 Tahoe`s transmission problems. One customer reported to Consumer Reports: “Vehicle shifts roughly while downshifting. Initially it was thought to be the torque converter but now we`ve been told it`s just the way it is.”
Bad habits such as parking without the handbrake, changing gears incorrectly, and shifting an automatic transmission before the car comes to a complete stop can cause your transmission to wear out prematurely.
Grinding noises, transmission leaks, burning smells, noisy idling, and shifting delays are all common symptoms of a clogged filter.
Rusting, power failure, irregular pressure, missing equipment, an incorrect amount of voltage or current, dirt stuck in the system and corrosion are some of the possible reasons why a solenoid valve may not properly close or open.
When the torque converter starts malfunctioning, you may feel shuddering and even slipping in overdrive. You usually notice your car shuddering because it feels like it`s vibrating. Your car will vibrate even when you`re not going very fast. The shuddering makes the car lag and is very noticeable.
At this point, the converter is said to be “coupled hydraulically.” Under these conditions, up to 10% of the engine`s output power could be lost to the torque converter`s internal slippage. This accounts for most of the mpg difference between a standard and automatic transmission vehicle.
Rattling is one sound you want to be aware of. If you hear odd rattling sounds when you accelerate, this might be a symptom of a bad torque converter. The same can be true of whirring noises.
This transmission will support up to 450 RWHP. C5 Corvette 4L60E CORE REQUIRED.
Their Stage 2 Pro Race transmission can handle gobs of power while their Invincible Black Edition 4L60E trans can support over 1,000 ponies.
Luckily, transmission failure doesn`t usually happen without warning. There are several warning signs that your transmission`s going out.
There are 6 ways to improve automatic transmission performance and reliability. These are servicing the transmission, changing driving habits, driving with lower gears when loaded, maintaining engine performance, having proper alignment of tires, and having the correct tire size.
Here`s a fact: manual or automatic transmission upgrades can do a lot of good for your car, starting from an increase in acceleration to ensuring that your transmission components do not break down when you least expect.
This is because the engine`s power is much more likely to break less powerful and smaller transmissions. But then, the 4L60E automotive transmission is powerful enough to work with the engines of most stock automobiles.
Maintain Proper Transmission Fluid Levels
The #1 cause of transmission failure is low fluid, which causes overheating. In automatic transmissions, it causes delayed engagement, harsh shifts, and slippage.
Automatic transmission problems can be caused by a lack of transmission fluid. If you are experiencing slipping, the first thing you should do is check your transmission fluid levels. If they are low, you should top it up and check for leaks. Slipping can also be caused by burned or worn out fluid.
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.

My truck won’t allow me to change gears even when pressing the clutch. No gears go in at all. Makes it impossible to drive.
ANSWER : Hello, this concern is possibly the slave or clutch master cylinder failure. These two components use brake fluid to apply pressure for movement of the clutch system. This fluid breaks down in time and causes the seals to fail (leak). A low fluid level would cause this concern as well as internal leakage. Replacement of components would be necessary. This type of concern would need to be inspected. If you’d like, a certified technician from YourMechanic can come to your location to diagnose your vehicle, and possibly replace your clutch master cylinder if need be.

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.

When i put the truck in 4×4 it makes a creaking noise and when i start to make a turn the truck wont turn all the way
ANSWER : Hey there. It is possible that it may be time to change the differential fluid, as this symptom is common when the differential fluid is dirty or low. This service is typically due every 100,000 miles. It is also possible that an internal component inside the 4WD housing has been damaged. This type of noise is also common with power steering issues or damage to tie rods and ball joints. Due to the multiple possible problems that could be causing these issues, it’s best to have a professional mechanic complete a car is making a noise inspection.

Power steering is making noises seems like is looking power does the power steering pump makes the car to automatically stops lock
ANSWER : Noises from the power steering system can be due to low fluid level, as well as a loose drive belt, so be sure to check those two possibilities first. If there is still no resolution, that is if the noise problems persist, you should request a steering noise diagnostic. If faults with the power steering pump are causing the engine to loose power, then you should mention those issues to the mechanic when he does the noise diagnostic so that the mechanic can evaluate the freeness of the pump pulley and look for other faults. If, though, the engine is losing power, due to other causes such as ignition or fuel system faults, those will have to be separately diagnosed.

car making womp womp noise and pop
ANSWER : A common cause of a noise like that is tire belt (internal) separation, flat spot(s) on tire or other tire defects. If the tires end up being excluded during a diagnostic, the CV axles, wheel bearings, and unfortunately the transmission and clutch have to be considered. The noise on turning is suggestive of a possibly defective outer CV joint but very loose tie rods ends and ball joints can sometimes be implicated. Also, it is possible to have a bad strut bearing, in the strut mount. Keep in mind, a "combination" of faults might be in play here. Your best bet is to request a front end inspection/diagnostic during which the responding certified mechanic will get this resolved for you insofar as identifying the root cause(s) and estimating the repair for you.

The truck wasn’t starting up or making any noise. I replaced the starter and it still doesn’t want to start up. It just makes a clicking noise
ANSWER : Hey there. You have a bad battery or there is a bad connection in the starting system. The battery should be load tested and the state of charge should be checked with a hydrometer. Your starter requires about ten times more power from the battery than any other system in your car. Even if the headlights and all other electrical components work, it is not a good indicator of the condition of the battery. So a thorough testing of the battery should be performed first.
If the battery checks out, then the problem is a bad connection in the starting circuit. The first test I do, which may be irrelevant since you have already replaced the starter, is to tap on the starter with a hammer while someone is attempting to start it. If it cranks the motor, it needs a starter. It is possible a new starter is bad, so there is still some value in performing this test.
If this doesn’t reveal a bad starter, another simple and test is to attempt to crank the car for up to thirty seconds. Pay attention to smoke or any electrical burning smells that might occur. If you experience one of these, immediately stop and look under the hood for a hot spot in the battery cable connections. Feel both battery posts, the positive and negative battery cables, the ground connection at the frame and the main power connection at the starter. If any of these are hot or warm, it is a bad connection.
If that doesn’t reveal anything, the next step is to use a test light to see if the starter solenoid is getting power from the ignition switch. If it is not, you will need to use a test light to find our where the connection is lost. The suspect parts are the ignition switch and the neutral safety switch (aka the transmission range switch). You will need access to a wiring diagram and a test light for this portion of the testing.
If you should require further assistance, I recommend having a professional technician, like one from YourMechanic, diagnose your starting issue so that this can be repaired.
