I have a 2002 chevy silverado 1500 4X4 Z71 with the 5.3L V8. The original trans. went out and was replaced with a used 4L60e. Now the transmission wont engage any gear. after researching ive come to the conclusion its the wrong model 4L60e. My truck has the automatic 4WD button in it which if im not mistaken changes the electrical part of the trans because it uses speed sensors. correct?
The transmission that replaced the original one is a (9LUD). It should actually be a (2KCD) correct? Or if you could tell me what transmissions (4L60e) models i can interchange with. Does the Z71 designate it as having the Automatic 4WD?

Check out this site. Their chart says that transmission is a 99 model year. Maybe that trans wan't the original for the suburban. Or they are jerking you around. What was wrong with your trans? Just

It can have the 4l60e or you can install a 4l80e, if thats what you are asking. The z71 should have auto 4x4 as a standard option

Thank you for the response. Let me give you a little more background info relating to the situation. The original transmission went out about 6 weeks ago. A replacement transmission was purchased from a auto salvage yard. It had supposedly came out of a 2003 Suburban 2500. Now this is where the problem begins. The model number of the replacement 4L60e trans is 9LUD. The trans that came out of my truck was a 2KCD. My truck has the Auto4WD button as well as push buttons for 2LO,4HI and 4LO. From what ive been able to conclude is that the replacement transmission 9LUD is not designed for the trucks with thw Auto 4WD option.

The problem im having with this transmission is that it wont engage any of the gears. I was not aware of the different 4L60e transmissions prior to installing it, unfortunately. Now i think ive educated myself a little about them but would like a second opinion from someone more knowledgeable on this than i am.

Am i correct in thinking that the 9LUD is not a compatible replacement for the2KCD that came in the truck originally?

Also another thing that before i installed it wasnt aware of but was told by the salvage yard that i got it from that they supplied me with the wrong torque converter. But i know this is now not true. The torque converter they gave me was the matched one for the 9LUD but the bolt pattern to mount it on the flex plate in my truck wasnt even close plus the TC in my truck is much larger.

So i hope you can decipher from this what i am trying to figure out. I have dropped the trans out again and i am scheduled to return it to salvage yard on Monday 6/2/14 for an exchange but want to be sure i know what to look for as far as id numbers etc on trans to be sure its correct this time.

Thank you very much for you time and suggestions.

I'd get my money back and never buy a used transmission again , if you're keeping the truck , get a rebuilt transmission or have your old one estimated

 

IMO you're wasting your time

Yes i agree with both of you 100%. I know i refered to it as my truck but in reality its a good friend of mines truck and she was led to believe that the trans mission was purchased as being rebuil etc. by the person who took out the original trans and put thie piece of junk in. Now im just trying to straighten out the whole thing and get her what she needs to get her truck back on the road because in the mean time shes using mine. So you can see why im desperate to find the right info.

Also unfortunately the salvage yard wont refund money just exchange only. But thats another whole story in itself.

 

Thank You very much for your time and for sharing that info.

 

IMO if i were her would take the loss and considerate a learning experience. Then break out the piggy bank and get a rebuilt one and have it installed professionally. Although i think i am capable of the job i dont need the headaches resulting from it....LOL

 

Thanks again.

If you used a credit card to buy the tranny, just explain it to the CC on. and they'll cancel the charge.

So you can't just use any 4l60e they have to have the same features?

You can use any 1/2 ton 4L60e Trans the transfer case makes no difference.

 

Years that fit 99-06-07 classic truck

2000 NBS - 2006 full size Suv

 

Sounds like the OP got a bad used transmission.

I have a 2001 GMC Sierra 1500 series extend cab, blew the transmission. I have a transmission out of a 2001 Chevy Silverado 1500 series extended cab which I think is the 4l60, will this transmission fit my GMC?

      Some Assembly is Required

      www.enginelabs.com/news/what-i-learned-today-bearing-clearances-vs-oil-viscosities/     www.enginelabs.com/news/oil-viscosity-can-the-numbers-be-misleading/ The Big Lie… Coming full circle to the reason Lake discusses the Porsche engines in particular. Based on the 2000 samples in the SPEEDiagnostix database, increasing the oil viscosity in these engines, even those run on the track, showed no significant difference in results.   The smoking gun was in the oil chemistry. That is where the data shows higher instances of more wear. Molybdenum was the key; the higher the amount, the less the wear. Speed postulates that higher viscosity oils have more thickeners to artificially inflate their viscosity numbers. These thickeners lose viscosity under shear, and the result is that not all oils of the same viscosity have the same shear stability.   Having enough viscosity is the most important characteristic, but according to Speed, once that required viscosity level is reached, additive chemistry matters more than additional viscosity. Speed also states, oil pressure problems on the racetrack aren’t a viscosity problem; it’s an oiling system problem. Running a thicker oil is just a band-aid for an underlying oiling system problem.

      Can it still be Assembled II?   Viscosity on the decline by various means. Heat on the rise making that worse. Engine RPM in the tank. Smaller motors with more boost trying to emulate an electric motor. Full torque, zero rpm. Then we will triple the OCI. Argh.    But wait....there is more. LSPI has pushed a shift from Ca to Mg and as that cost more PLUS the run to lower sulfur compounds the TBN is moving in the wrong direction for the increased OCI's demanded.    That not being enough to placate a demand for a parameter they can't measure the other sulfur bearing compounds are also under attack. That would be zinc and phosphorus sulfonate compounds. To some degree those are being replaced with boron esters and others, i.e. titanium ect. All of which have shorter service lives. And there there is the "Secrete Sauce" marketing for AW adds that 'Can't be detected by UOA's" but trust me because I (the blenders) never ever lie.    Spoiler alert; ALL additives are sacrificial! Smaller amounts of the old blended with less robust versions of the new do not equal longer service lives. So what are the blenders recommending? Wait for it.......   MOVING THE GOAL POSTS! OMG      Let's declare the long standing TAN/TBN crossover irrelevant and tell people that soot is a great 'graphite' based lubricant which can aid tribo films. Wait, what? Let's declare that the standards used for oxidation and nitration were to conservative and can be expanded. Let's tell them that because GDI fuel dilution, although being a VISCOSITY KILLER and an acid generator is actually okay because we have better base oils that limit viscosity failure limits. (Said knowing this is measured in fractions of a centipoise and in bases not commonly used in shelf oils)   Lying from the heart is not just the new normal but we have a public, a very young public, that is so ignorant of the facts and so sure of their "RESEARCH" into AI driven models base in regurgitated  instead of scientific research based unvarnished, peer reviewed FACTS that the incoming guard is loosing their grip on reality and the OEM's are tickled pink while the blends bend the knee.    You have an ever limited set of tools to work with. And sooner or later those will be taken from you as the API and the EPA strangle the last remaining fluids from the system. What you have left is your wits. If you care to use them.    At some point in the very near future it will not longer be possible to do "What is best for the machine", and be replaced with "The best you have access too". You WILL be rewarded with half the life and twice the cost. That isn't that hard to predict.

      Software Update

      I trust you saw the other comment where he knew what he was talking about !. Yes, these darned newer vehicles with all their so smart they are stupid technology, goes and drains the battery down. As you might see my other comment, I installed a Noco 5 battery tender under the hood and at this point still have the cord routed so I have to lift the hood and then plug it in but am typically parked in a garage or a shed so its not risking the engine hood in the wind. That way I am assured or hopefully so of not finding I have a battery drawn down and can't even start the truck and that also damages the battery to draw it down too far.

      I guess no surprise my guesses were wrong !, at least now I know if I ever happen to see it grayed out in my own truck as to what is going on.    I never happened to catch my truck with it grayed out, it seemed every time I would test to see if there was an update it never found anything and yet more than once I would check to see if there was an update and there was nothing, then a day later or even that same morning I would drive to town and after more than one engine shut down in town as I did my errands it would pop up that there is an update now ready to install and the only place I have a connection to the internet is at home by wifi so its not as if it grabbed the download while driving. I don't trust these new vehicles due to all the crap they can decide to do while sitting for some days not running and run the battery down so most of the time if I know the truck will sit for a few days I plug in the battery tender I have mounted under the hood and so the only time the truck must have downloaded software was when it was sitting in the garage where the signal is awful but I have that tender plugged in and somehow it managed to download it. I honestly detest all this crap, way to easy to leave a person stranded.    Since I don't trust any of it I don't do the install of the already downloaded software until I get home and sometimes have even sat in the truck to watch what its doing as its going through the process to its conclusion as its not like it is set up that it will tell you the next time you fire up the engine that the update that was initialed actually installed or installed properly. Yes I can go into the updates and see the list. After I go through the install where I feel its safe to do so in case it breaks down as a result, I will plug in the battery tender after the fact to recharge as I don't know how much power its taking just to do the install and that can take a while for it to install.

      Thanks for the reply. All settings were correct and the engine was off, as it was supposed to be. It turned out to be something simple. I took a drive for about an hour. I must have had a low battery without knowing it. The voltage gauge on the display looked ok. At the end of my drive, I shut off the engine and the update prompt came up and it updated normally. It’s ironic because one of the features of the update is a reduction of battery drain.
