There are also differences when it comes to the sensors, mainly that the 4L80e do have 2-speed sensors that are different than the sensor on the 4l60e. If your car model came from the factory with the 4l80e, get a dipstick from a transmission that has been fitted in one of these cars. For an example, on the first gear, the 4L60e have the gear ratio of 3. Here are the things you have to consider about. In a summary, the 4l80e is larger and can take more power than the 4l60e. This size difference means that they are not easily interchangeable.
For example, the flat flexplate used with the spacer is designed for a 300mm 11. There are actually two quick fixes for this situation. If you have a 4L60e you can probably also go to a junkyard and find parts for your transmission, depending on where you live. The L indicates that the engine is longitudinally positioned. These transmissions look very similar next to each other in pictures, but when compared side by side in real life the 4L80E dwarfs the 4L60E Differences between the 4L80E and 4L60E The 4L80E is noticeably larger and longer than the 4L60E. As you can see in the photo, the 300mm bolt pattern holes can be carefully elongated with a file or die grinder to accommodate the smaller Gen I converter bolt pattern.
This condition is made even worse when using the Keisler bellhousing with its 0. It goes over everything that you would need in order to pull off the swap. Can you swap between them? From the factory, the 4L80E is more capable than its sibling. Installing a shift kit is an easy upgrade you can do at home jpg 1200x900 4l60e how to install the transgo 5eat hd2 shift kit a detailed walkthrough subaru legacy forums how to install the transgo 5eat hd2 shift kit a detailed walkthrough subaru legacy forums aro firebird corvette 4l60e transmission problem fix why am i receiving autotap code p1870 4l60e 4l65e Transmission High Performance 4 8 5 3 Ls1 6 0l 2wd How do you r the transmission valve body in a 99 tahoe 4l60e with 4l60e valve body bolt location topsimages 5r55e vb torque sequence ford explorer and ranger forums 4l60e embly gm 4l80e valve body 2004 up 1 year warranty sonnax updated and. The 4L60E is rated to handle up to 360 ft·lbf 488 N·m of torque. Remember that these are the main differences and you can find other small differences if you go in-depth researching. Gear ratios Another big difference between these transmissions that are important to think of if you are going to swap them, is the gear ratios.
These trans choices not only limit creativity but also tend to be more expensive. It is my opinion that there is almost no situation where a built 4L60E is not going to be the better performance choice. However, you can also find both new and used transmissions and parts online and one of the places to check for these are on Amazon. The part numbers for these pieces can be found in the parts list at the end of this story. I created this blog to share the knowledge I have collected through the years, and I hope that you will find the information helpful.
If the car that you are swapping the 4l80e transmission into did come with that transmission from the manufacturer, you can get one of these crossmembers and install on your car for a plug and play situation. This appears to be the stumbling block to getting the engine low enough, as there are engine oil pans that barely hang lower than the flex plate and still hold 8 quarts. If not, there are a lot of shops that can make the driveshaft shorter for you. One thing to consider is that the 4l60e was named th350 and before in earlier models and the 4l80e was named th400. Max Torque Since the size of the transmissions, there is also a large difference between the durability of these transmissions when it comes to performance. Just with these number, you can probably calculate that there is a big difference in size and weight between these transmissions. Since the input shaft length on our traditional four-speed or five-speed transmission has not changed, we also have to move the position of the pilot bushing rearward to compensate for the discrepancy.
Before we bolt on the bellhousing, there is one other crucial step that must not be overlooked. They also have different input shafts and torque converters. If you want to find parts for these I can recommend you to check for it online. Another thing to take away quick as that they are almost never easily swapped for one another even in vehicles that they both came in. McLeod has again come to the rescue with an adapter pilot bushing that sits in the larger recess in the crank and therefore supports the input shaft in the proper location.
This article relies largely or entirely on a single. If you want to swap to one of these transmissions remember to also purchase the control unit and the harness. That is until you get to crazy horsepower numbers. I think I did cover the most important parts when it comes to the difference and the swapping between the 4l60e and the 4l80e transmissions. Please help by introducing to additional sources. This transmission can still be found in light-duty van applications as well as in the overseas market in the Holden Commodore. This position minimizes linkage movement while maximizing throwout bearing travel.
Categories , , , Post navigation. Not-So Shortcuts Car crafters are the masters of adapting parts to achieve a solution. In our trans-swapping effort, remember that while the depth of our bellhousing is the same as with a Gen I engine, the crankshaft flange is 0. They are different lengths, so they will automatically require different driveshaft lengths. In 1996, a bolt-on was phased in along with a six-bolt tailhousing for S-10 Trucks and S-10 Blazers and beginning in 1998 for all other applications.
