What could be causing metal shavings in a transmission pan?
I can assume you've dropped the pan on your transmission ...really the only way to see the metal "dust" in the pan. Since you are talking about a pan, I'll also assume you're dealing with an automatic transmission.Some of this is normal wear. If this is the first time the pan has been dropped since the vehicle was new, there's a good chance all that fine metal powder that's collected on the pan magnet was from the break in period. And there'll be some small amount just as a function of normal wear. You have multiple clutches and gear sets regularly and constantly engaging and meshing. There will always be some level of fine metal powder stuck to the magnet.Now "shavings" are a different thing. If what you have is a powder-fine deposit of metal clinging to the pan magnet that's normal. If you have actual shavings ...chunks, bits and stuff that are larger than fine powder ...then you have some potential issues. How old is this tranny? Mileage? Do you use the vehicle for towing?Actual "shavings" are a sign of some internal wear above what would be considered normal. The actual cause, if these are actual shavings, could be from a lot of things ...none of them good.
Are 4l60e transmissions interchangable in the 1989-1998 Chevy and gmc k1500??
I own a shop, and think this; The electronics are in fact different between a 94 and a 95. The 94 uses an OBD-1 computer, and the 95 uses an OBD-2 computer system. Both of them are (should be) 4L60e transmissions, and you should be able to swap the electronics from the 94 to the 95, and make it work, but this I'm not 100% sure of. The best way to find out, would be to call a junkyard. They pay big bucks to get a program, or books that tells everything that will interchange. This may even involve removing the pan, and changing the electronics inside the transmission as well. The speedometer connection may also be different in how it is calibrated, or the pulse it supplies the computer. Glad to help out, Good Luck!!!
What are some symptoms of too much transmission fluid?
Excess transmission fluid will cause foaming in any transmission. Foam does not flow like oil, reducing cooling and lubrication. It also implodes on compression between gears or in the hydraulics of automatic transmissions, causing severe damage (pitting).In an automatic transmission, you will have higher temperatures and poor shifting, as it depends on solid hydraulic pressure, not spongy foam to move the clutches and bands.Automatic transmissions with dip sticks should be measured with the engine running, and consider the operating temperature. Note here how the heat affects the measurement. It should not be filled to the top when cold, or checked not running.If it does not have a dipstick, it is measured with the plugs on the side, depending on specific instructions per brand of car.Manual transmissions normally don't have dipsticks (some do). They are checked from a plug on the side of the transmission, and the level should normally be at the level of the plug, not above.
Transmission Fluid - Chevrolet Tahoe?
Ron, What most likely came in your truck from the factory is Dex 3. However, since that was created, Dex 6 has come out as a much improved fluid. Before you go and flush your 4L60E, there's a few questions you should ask yourself.... If your tranny has never been "flushed" (all fluid removed and replaced) before, I would recommend simply dropping the transmission pan and replacing the filter. This will net you a few quarts of new fluid. If you service your transmission somewhat regularly (i.e. every 60k miles), then you should be ok with a full flush. I don't ever recommend the use of cleaning agents, so if do a complete flush, don't use cleaning agents. Also, if your transmission is currently slipping and/or you have other problems with it, DO NOT flush it...it will only make the problem worse. If you do have these issues, bring your tranny to a repair shop b/c new fluid is only going to drain your wallet. If you have the shallow transmission pan, your system will hold about 11quarts and you're going to need about 5 or 6 extra quarts of Dex6 to complete the flush. If you have the deep pan, your system is 13.1quarts and you will also need about 6 quarts of additional fluid for the flush. Make sure you know which pan you have so you can order the correct filter.

Will a 1998 4L60E transmission fit in a 1996 Chevy truck?
Well, the difference is the bolt pattern on the tail housing, and the 'late' model 60E has a removable bell housing. To my knowledge, the rest of the trans is the same, and it should plug in and shift as normal; I am not positive on this, yet. You will need to swap the tail housings so that you can mount your transfer case. Read: http://www.novak-adapt.com/knowledge/4l6...
How do you locate and fix a transmission control module?
The transmission control module is a very important component of the automatic engine transmission systems that run most modern cars. It helps the car engine calculate how and when to change gears for optimum driving performance.How to fix transmission control module:Turn off the Ignition: It is impossible to fix a transmission control module when the vehicle's ignition is on. Keep your vehicle in a dormant state, and when possible, disconnect the battery completely. Engage the emergency brake, and then shift the gear in the park or neutral position to achieve this.Locate transmission control module: the transmission control module is in the distributor cap under the hood. However, the module may sit at the bottom of the steering wheel or under the dashboard, depending on the model of your car.
Why does my transmission slip only when it is cold?
I own a transmission shop, and the #1 cause for this is the transmission is low on fluid. Fluid expands & contracts to heat, and when it gets warm the fluid expands enough to work properly. Check the fluid level this way. Run the vehicle until its hot, park on level ground, engine running, place in park, and check the level at least 6-8 times, and if you look at both sides of the stick you will see its lower on one side than it is the other, so you must go by the lower reading. The reason for this is, when you pull the stick out, it will drag fluid up the tube with it, and a false reading is very easy to do. It sounds like you are about 1/2 of a quart low, or better. Don't over fill the transmission, and if you do you will have to use a hand pump to pull some back out through the fill tube. If its not low, then its sucking air somehow around the new filter you installed. A common mistake is installing the gromet for the filter into the valve body without removing the old one, or damaging the new one or the transmission case by scratching it when removing the old gromet. If it was scratched, then use some 400 grit sandpaper to remove these scratches, and use a socket with a shot extension to install the new gromet up in the case. These gromets are really hard to install with the transmission in the vehicle, so I do it with a socket that fits the seal, but doesn't hit the case. They make a tool for this, but a socket of the right diameter will work ok. I have seen the filter just fall out back into the pan and cause this too. Advance Auto parts carries some stuff called Lubeguard that you can get to put in the transmission that will help with the shifting issues. The valves in them will stick, and cause the shift issues, and this rings especially true when the weather is cold outside. You would be looking at about $1,200 - $1,600 for a rebuild depending on where you live. You could get a good used one from a junkyard with low mileage for about $800, plus installation. This transmission is not a cheap one to have done, and may even run as much as $2,000 in some area's. Glad to help out, Good Luck!!!
Why is transmission fluid in my coolant?
Mike Allen hit the nail on the head.The transmission cooler “lives” inside one of the tanks of your radiator. Most modern radiators have end tanks. Older cars have the tanks on the top and bottom. Regardless, you can tell where the tranny cooler is by looking for a pair of steel lines that enter the tank. The tranny cooler is the only interface where coolant and tranny fluid could possibly be intermixing.In order to fix your problem the radiator will have to be replaced; the tranny cooler is built integral to the radiator and not a separately replaceable component. It will no doubt be strongly suggested you flush and replace the transmission fluid …possibly replace the fluid filter …and flush and replace the coolant. This might cost the better part of $1000 …like 6 or 700 …depending on how expensive the radiator is.And like Mike suggested you need to get it fixed. I’ll go one better …like yesterday.
What will happen if I drive with a very low transmission fluid?
It depends on whether your car is an automatic or manual transmission.Automatic: Automatic transmission fluid has multiple jobs in an automatic transmission. First, it is used for cooling the transmission. So, with low transmission fluid, your transmission will not be cooled properly. Second, it used to make the torque converter operate, and provide pressure to ensure proper operation of the various clutches and components within the transmission. Third, it is used to lubricate your transmission. If your transmission fluid is very low, the transmission will almost certainly be slipping. So it will feel like the vehicle is in neutral, with the engine revving, but no power being applied to the wheels. The shifts will be rough, if they occur at all, as the clutches are not getting proper pressure to perform shifts smoothly. If the transmission fluid is very low for a long period of time, the clutches will burn up from not being able to lock up properly, and the torque converter will likely fail due to improper fluid pressure. If you drive your automatic transmission vehicle with low transmission fluid, at some point, you will be looking at a bare minimum $2,000+ repair bill unless you are able to do the work yourself, in which case it will still be $1,000 plus.Manual: In a manual transmission, low transmission fluid will cause the gears, synchronizers, shift forks, and other components to wear quickly. The bearings within the transmission will also not be lubricated properly, and the transmission will begin to overheat. It will likely be quite difficult to shift the transmission between gears, if not impossible. A manual transmission with low fluid may last longer than an automatic transmission with low fluid, but the prognosis is still the same. Transmission failure will occur, at some point, sooner or later.If your transmission fluid is low, it is much cheaper and safer to fill it, rather than face the expensive repair bill. Fill the transmission fluid and keep an eye on your vehicle, as it is likely that you have a leak, especially if your transmission fluid is frequently low.
