Question about 2003 Chevrolet Silverado 2500HD

1 Answer

Transmission comes out of gear and makes small grinding noise.

When you let off the throttle it goes right back in. When manually shift it holds in all gears. PO Codes 700 and 735 on scanner. Changed neutral safety switch and Solenoid A and B. Looking for idears where to look next.

Transmission making loud grinding/sucking sound, doesn't go when in drive or reverse


Is it an automatic John? When was the last time you checked the level of your ATF (automatic transmission fluid)?

There are many different types, so make sure you get the right one.

If it is a manual shift, check the gearbox oil level. If that is OK, you need a transmission specialist. Look in Yellow Pages.

You must have a manual transmission. Rebuild it. synchronizers are bad. The reason for grinding. Then you have worn shift forks. Reason for popping out of gear. Also replace any worn bearings or just get the bearing kit and replace them all, with the races.

Grinding clutch


I'm a little confused on your description of the noise. If I understand you correctly It is making the noise when it shifts smoothly into gear but at the same time it makes a grinding noise ? It possibly can be synchronizers if the grooves on the inside of the synchronizers are worn bad enough to where the gear isn't slowing down enough causing a grind as the clutching teeth on the gear mesh with the synchrode and the shift collar.
If it is making noise in all gears except 4th you may have countershaft brgs failing. The power flow in 4th gear goes directly through the mainshaft and has a 1 to 1 ratio. All other gears the powerflow goes through the countershaft causing a load on the countershaft so if you have bearings failing in the countershaft you will hear noise in all gears but 4th.
i hope I understood you correctly .

What is it when in reverse the automatic transmission on a 1999 Camaro grinds?


Reverse is not "synchronized" forward gears are, so it does make some noise, try shifting to 2nd before engaging reverse to slow gear rotation and limit gear clash or grind.

No one can tell you what it is.This is the operating characteristic of your transmission and customer do object to the noise or clunk and dealer discourage the repair. This is TSB 03-07-29-004G. Let me give you a partial copy. INFORMATION
Bulletin No.: 03-07-29-004G
Date: December 15, 2010
Subject: Manual Transmission Operating Characteristics
Cold Operation
Manual transmission operation will be affected by temperature because the transmission fluid will be thicker when cold. The thicker fluid will increase the amount of force needed to shift the transmission when cold. The likelihood of gear clash will also increase due to the greater time needed for the synchronizer assembly to perform its function. Therefore when the transmission is cold, or before it has reached operating temperature, quick, hard shifts should be avoided to prevent damage to the transmission.
Backlash
Backlash noise is created when changing engine or driveline loading. This can occur when accelerating from a stop, coming to a stop, or applying and releasing the throttle (loading and unloading the driveline). This will vary based on vehicle type, build variations, driver input, vehicle loading, etc. and is created from the necessary clearance between all of the mating gears in the transmission, axle(s) and transfer case (if equipped).
Shift Effort
Shift effort will vary among different style transmissions and synchronizer designs. Usually the more heavy duty the transmission, the higher the shift effort because of the increased mass of the components. Shift effort can also be higher in cold weather because the fluid will be thicker. Medium duty transmissions will not shift as quickly as a Corvette transmission. To reduce shift effort, do not attempt to rush the shift - allow the synchronizers to work as designed. Shifting harder will only increase the chance of rushing past the synchronizer leading to grinding while shifting.
Non-Synchronized Gears
Some light duty truck transmissions in 1st gear (creeper-gear) and reverse gears in various transmissions, along with all gears in some medium duty transmissions, may be non-synchronized. This means there is not a mechanism to match input and output shaft speeds to allow for a smooth shift. This function is left up to the driver. This can be noticed if a shift into 1st or reverse is attempted while the vehicle is rolling or before the input shaft stops rotating leading to a gear grind. The grinding can be reduced by coming to a complete stop and pausing for a moment before shifting into the 1st or reverse gear. Some slight grinding can be expected. In medium duty non-synchronized transmissions, the driver must match input shaft (engine) speed to output shaft (driveshaft) speed with every shift. This can be accomplished by double clutching, or by using other methods. If the driver is not able to perform this function properly, there will be gear grinding with each improperly completed shift. Driver training may be required to correct this condition. Clutch brakes are used in medium duty non-synchronized transmissions to allow a shift into gear at a stop. The clutch brake is used to stop the input shaft from spinning, allowing a shift into gear at a stop without grinding. The clutch brake is activated by pressing the clutch pedal all the way to the floor. When the clutch brake is used, it is possible to have a blocked shift with the vehicle stationary. If this occurs, engage the clutch slightly to rotate the input gear to allow the shift. The clutch brake is intended to only be used while at a stop. Care must be taken to not activate the clutch brake while shifting between gears. This could lead to excessive grinding or a blocked or missed shift.

Have the transmission repaired or replaced. The shift arm that shifts the gears is probably broken. That is why you cannot switch gears and is making that noise.
