What causes a hard shift on a Silverado?
A 12 Hz electrical feedback from the charging circuit may be affecting the transmission pressure control solenoid, causing a fluctuation of the line pressure within the transmission. Throttle position is less than 15 percent. Engine coolant and transmission fluid are at full operating temperature.
Can a Chevy Silverado shift from 2nd to 3rd?
No 1st or 4th, shift 2nd to 3rd by itself when put in D or OD and locks converter: Goes into gear but sluggish like brakes are on, can manually shift to 2nd to get moving, then put in OD and truck shift 3rd as well as 4th are OK. Also, torque convertor locks up.
Can a shifting solenoid be replaced on a Chevy Silverado?
A shifting solenoid is pretty easy to replace; although, you have to remove the transmission pan to change them. A general trouble code may show that the transmission is slipping, but not pinpoint what the issue may be. Figure 2.
Are there no reverse gears in a Chevy Silverado?
No Reverse in 2nd or 4th gear, 1st and 3rd only: Transmission goes into gear harshly, vehicle sluggish from start, no 1st, 4th, or torque convertor lockup, manual 2nd, 3rd, reverse gears only working, check engine light is on: Transmission is in Limp Home Mode or has no electrical power. Also, PCM has lots of error codes.

Why is my shift gauge not working on my Chevy Silverado?
Gauges that are not working could mean a faulty ignition switch. This has been an issue on this truck series. A bad ignition means that there may not be full voltage available to activate the shift solenoids. Replacing the switch will cure the problem. Figure 1. Look for blown fuses or damaged wiring.

Why does my transmission shake when I shift gears?
One of the most common causes of transmission problems is low transmission fluid. Transmission fluid provides the lubrication between the gears of your transmission as it shifts.
What causes transmission to shift from first to second gear?
Some customers may comment that the transmission slips, a shudder, chuggle, or vibration is felt when the transmission shifts from first to second gear. A 12 Hz electrical feedback from the charging circuit may be affecting the transmission pressure control solenoid, causing a fluctuation of the line pressure within the transmission.
Why does my car clunk when I shift gears?
Low Transmission Fluid One of the most common causes of transmission problems is low transmission fluid. Transmission fluid provides the lubrication between the gears of your transmission as it shifts. If there is not enough transmission fluid, the vehicle may clunk into gear as it shifts without the protection of lubricating fluid.
Why does my transmission shift hard from 1st to 2nd gear?
The fluid gets dirty over time and when it does, it causes plenty of troubles. Hard shifting is one of them. If the color is dark brown or burnt, changing it is likely to solve this issue. Dirty transmission fluid. (Photo Source: procarreviews)
How to hard shift from 1st to 2nd on a Silverado?
Route the black wire to the generator BAT terminal, sliding the wire into the small end to the output terminal boot, along side the generator output wire. Crimp and solder the ring terminal, P/N 02977821, on the open end of the new black wire.

Why does my car shift late when I Shift?
Electronic sensors control when and how your automatic transmission shifts. If the sensors are not reading information about the vehicle’s speed and acceleration correctly, the vehicle may shift poorly, shift late, clunk into gear or not shift at all.
