In the future, I think I will just leave the gasket in, unless it pops right out unlikely. Do not just drain and change with a drain plug bolt if it has one The filter must be changed every 50k and the pan cleaned out. Installer is responsible for any damage to persons or property. I've never changed the trans filter in this truck before. Before I start on this I want to confirm that those values are accurate. Are there low-profile pans for the 4l80e?.
My uncle doesn't know the last time it was changed, and I can't ask my father when the last time was he serviced it. If turning over a not firing, I would check the distributor for damage from lifting the engine. Most of that stuff is in my 'work' garage behind my house, and I have this truck in my regular garage that's attached to the house and have no 220 set up there. I created this blog to share the knowledge I have collected through the years, and I hope that you will find the information helpful. In a summary, the 4l80e is larger and can take more power than the 4l60e.
I have a welder, but no access to it where the truck is at. Click on an image to view larger. There are a lot of differences in these transmissions and here are some of the things you have to consider if you are going to swap the 4L60e to a 4L80e transmission. You can either get a special adapter kit which is normally including a spacer and an input shaft to make it work with your converter. Always verify your transmission and clearance. Outer Case Material: Aluminum Controlled by Computer: Yes Weight: 187 pounds without the converter If you were to look at them side by side it would be a no brainer which one is which.
The 4L80E is a computer controlled transmission and the successor to the. Transmission tunnel Because of the larger size of the 4L80e transmission, you may have to modify your transmission on the car that you are going to swap it to. Oh, my sump does have a drain plug but after reading here, I didn't mess with it. Never get under a car that is on a jack! Do you need to change the filter? If not, then you might back up and use a suction device to remove the fluid through the dipstick tube. So after my uncle gave it to me I started on some basic maintenance. He drilled and tapped the pan himself for a temperature sending unit.
Don't jack directly on the pan with the jack, you can dent or bow in the pan and the would be bad. Conclusion Overall, these transmissions are completely different even if they are looking almost the same. Is the above information right? The 6L80E, which is the successor to the 4L80E, has 20 bolts. If you want to find parts for these I can recommend you to check for it online. Look inside the wheel well and find the power steering rack. You can see the pictures of the gasket in the specification above.
Using flushing machines does not address the need for cleaning the sediment in the transmission pan, cleaning the magnet inside the transmission pan, or changing the transmission oil filter. Remove serpentine belt, let tensioner down, careful not to bash knuckles! These numbers can differ a lot and you will get a lot of different answers of how much these can handle. They both have the same forward gear ratios, only the 4L80E gets the overdrive gear of course. However, sometimes you have to use the hammer and a welder to make it fit properly. First you have to jack it up and stabilize it. I'm sure knowing how he was with taking care of vehicles it deffinitely was changed at some point, but as I said when he was in his last years he lost his legs and the truck didn't have much in terms of upkeep. Here are the steps he took to install this pan.
Joe The reason I have always heard for not having a drain plug in the pan is so you won't be tempted to just drain and fill the fluid, but not change the filter. Its not fun nor easy! Can you tell me what the torque specs are for this specific vehicle? Even if I had pulled the plug, there would have been that much trans fluid staying in the sump. A separate window or tab will open showing a bigger picture. This is mainly because of larger internals inside the transmissions. I'm not sure how true that is.
I can tell you what transmission you have if you can describe the shape of the bottom pan. If it looks different let me know. It will leak oil at an undetermined rate, depending upon how bad it becomes… If vehicle is equipped with a mechanical fan, take off the four bolts that attach fan to water pump pulley. And I got most of the fluid out that way, but I guess there was plenty left in the pan, because my truck was jacked up in the front but not the back. Many, many people have been crushed… You have to remove the transmission oil pan with the car safely raised. The bolt pattern for the transfer case is also the same so it will fit in a swap without problems.
Crossmember The 4L80e transmission case is longer than the 4l60e transmission, so the cross member has to be modified. Prett straight forward, reomove pan probly gonna get some oil spilt on yah, just a fact of life, no oil drain! That drain plug was weird though. If you do need to remove the pan, make sure you're using six point tools. In your photos those bolts don't appear to have significant rust on them. I'm really at a loss as to what to do, as I can't use any of the bolt-outs I have due to space, and all my efforts of trying to make some space and pretty much failed. Push the axles in from the outside. I changed it out, kept the original gasket but didn't change out the o-ring.
