But I didn't do anything reckless like loading it up all the time at every stop light, dropping it at 3000 rpms or downshifting out of 3-2 at rolling speeds, or excessive burnouts because it looked cool. These units still had the traditional bellhousing bolt pattern. 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. The only major difference is that the 4L65E uses five-pinion planetaries. Wow you have a 4L80e and did not noticed the weight difference? You can the transmission wiring harness swap kit here from Amazon: Dipstick The dipstick is different on the 4l80e transmission and you have to consider this when doing your swap.
However, some late 1996 van models also had bolt-on bell housings, while some applications in 1997 still had the earlier one-piece case. There are a few things that you really need to understand if you are to swap one for the other. Gear ratios: 1 2 3 4 R 2. Shop around, but cheaper isn't always a better deal when it comes to transmissions. They are also different lengths.
That be said I like this tranny when coupled with 373 gears. The goal in most applications is to maximize torque effiency. Similarities between these Transmissions If you are looking at the transmission they do actually look pretty much the same, depending on the year of the transmissions. This makes it possible for the 4L60E to be installed inside of application which are up to 8. It has better power flow for big power applications, much more clutch capacity and apply area than the 4L60E.
But some guys live by them. I know that the 4L65E is stronger and can handle more punishment. Are there low-profile pans for the 4l80e? It's an oversimplification, but it makes it a lot easier to understand for most people. Been a looonnggg time since I've been on this forum. In order for it to work better and more effectively, it has to have high quality parts inside. Scaled side by side with aftermarket converters my 4l80e was 44lbs heavier than my 4l60e. 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.
The two differ greatly in origin, performance, appearance and price, with the 4L80E being easily the more powerful of the two. How come nobody is agreeing within at least 20-30 pounds? This is not a 100% distinction though, because the early 4L60E models of transmission, which are created from 1992 through to 1997 have four bolt patterns as well. If you want to swap to one of these transmissions remember to also purchase the control unit and the harness. I am talking about a scale not he-man lifting after a few beers. At this point, almost everyone has tried everything and put it on the internet. The 80 actually fit better in the tunnel or around the top side of the transmission. The bolt pattern for the transfer case is also the same so it will fit in a swap without problems.
Here are the things you have to consider about. I swear I could remember reading somewhere that the only difference between the 4L60 and 65 is the internals. 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. Power loss through the transmission will increase the faster you accelerate it. It's a fleet truck and I won't have it that long anyhow. The longer pan was only a minor problem that required making cutout in X-member to provide clearance to fit it. An upgraded input shaft becomes mandatory.
You can either purchase an already premade cross member or you can do one yourself with a welder and some skills. Price Because the 4L60e is a lot more common than the 4L80e, there is also a big difference in the pricing of both used and new transmissions. We may not be the lowest cost but we back up our product and take care of the customer. Another difference between the 4L60E and 4L80E transmissions are the number of bolts on the pan. The mere fact that people are so interested in this topic is a testament to the absolute bulletproof reputation of the. Common problem with that on most cars from my research. The early ones 86-88 were known as the Turbohandgrenade for a reason Re: 700R4 vs.
These companies market horsepower because horsepower is sexy to the masses. I was real worried about using the 80 for my second swap but needed it for my power plans. Then the other feature I really liked was the Manual mode where I could choose my own gears. Converter weights will be similar for a given combination with the same size converter. This is mainly because of larger internals inside the transmissions. If so, from your guys' experience would the cost be a huge difference??? Thats just not my thing.
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. That is until you get to crazy horsepower numbers. The gear ratios in this transmission remain identical to the ratios in the 4L60E. I hope you enjoyed the guide! I've been babying it as of late hoping to get another year out of her. The 4L85 has heavy duty components to handle increased torque and horsepower requirements. Really the answer is either on would be fine. One of the most important bits is the transmission.
This is also the area where the cooler lines attach. 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. Can you swap between them? These numbers can differ a lot and you will get a lot of different answers of how much these can handle. It also sounds load like when your u-joints are worn. The 700R4 uses the computer to control the Torque convertor lockup, but you can buy an aftermarket kit to by pass that function. I'm convinced, I will wait until I can afford that tranny.
