Gear box in my l300 4x4 ute is makeing a clunking sound in all gears apart from 4th and when clutch peddel is down it isnt makeing the clunking sound any ideas?


The bearings in the gear box are gone. When in 4th gear the input and output shafts turn at the same rate 1 to 1 ratio. In all other gears the shafts are turning a different rates and the clunking is a slight meshing of the gears. When the clutch is depressed there is no power (load) on the input shaft.

Why would a vehicle in reverse move forward


The question is a little vague but I think I know what your referring to. All modern automatic transmissions have torque converters. This is the device that connects the engine to the transmission. All vehicle manufacturers like the trans to be nice and smooth shifting. That's great but it does come with some minor drawbacks. If you are facing slightly down hill and you put your car in reverse but do not step on the gas slightly I can guarantee that you will indeed roll forward. You can eliminate that issue by holding your left foot on the brake while you shift into reverse. Then, as soon as you feel the trans engage, gently depress the gas pedal with your right foot and it will eliminate that forward roll problem.

My transmission is clunking and grinding when I shift from park to reverse to drive


Does engage and drive normally? Because they only grind when you don't stop completely, gear grind. It is different to normal trans clutch plates engaging while you're riding on the brakes while shifting, they do make the 'clunk' - engaged - and then as you release the brake it grinds 'er er er er'.
So unless your trans doesn't drive normally, I'd say it's normal.

My 1999 Chevy Silverado 1500 Z71 makes a clunking noise and feels like it got rear ended if I drive it for an hour or so non stop. It seems to be when it shifts from 1st to 2nd gear. I had the ******...


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.

I was driving to work this morning and was in 3rd gear, went to down shift at a stop sign and its stuck in 3rd gear. 1988 jeep wrangler. It has been grinding the gear for a few weeks now everytime I change...


The 3rd Gear Synchro is worn or damaged, which is why it grinds when you try to upshift or downshift into 3rd gear. When it goes out completely you will have a very hard time shifting into 3rd gear, since the Synchro lines up the gears to make shifts smooth and easy.

I have a ford ka, and when trying to put it into reverse it made a weird clunking noise. And then wouldn't come out of reverse. I had to really push at the gear stick to get it out. I can't select any...


If the Gear is truck into unless the clutch disengages it wont shift. So start the car move slightly- if no space is a avialable jack up and let the drive wheel move- now shift the gear after depressing clutch. It must shift over now. If not repeat while the drive moves. You can now shift the car to forward gear .

Manual transmission is hard to shift into gears, when car is not running it shifts between gears smoothly, when it is running you have to push or pull extremely hard to force into gears


It sounds like your clutch may not be releasing full. Does it shift easily if you match the speed of the engine and transmission shaft closely? Does the clutch feel normal?

2005 Corolla's manual trasmission shifts gears, it clunks


hi mate , sounds like the SPIGOT bearing its a little bearing that allows the gearbox to be at a different seed than the engine flywheel and if this is in bad condition it will take the gearbox front shaft to a higher speed than comfortable for gearshift , in the meantime when you go for 1st or reverse gear just engage a gear like 4th without taking your foot off the clutch and then go for 1st or reverse, this will stop the gearbox spining long enough for a smooth shif, oNLY USE THIS METHOD WHILE STaTIONARY and see a professional when you get time.

2004 Jeep Wrangler - Clunking Noise when shifting out of Park


It could be lash in the differential which is normal, but it could also be a loose u-joint in the driveshaft. Check the rear driveshaft u-joints.
