A 4L80E can be made to run without any electronics but it has to be full manual valve body which would get old on a daily driver.Click to see full answer. Similarly one may ask, can you run a 4l60e without a computer?Externally, all it needs is a 12-volt source and an engine-vacuum reference. However, if your trans is, in fact, a 4L60E, running it off a computer is mandatory. Never mind TCC lockup; without a computer, the trans won’t shift at all.Subsequently, question is, can I replace 4l60e with 4l80e? 4l60e to 4l80e swap kit. Swapping from the 4L60E to the 4L80E is not difficult to do in vehicles that were equipped with both transmissions. It’s not the easiest swap to do, and a 4L60E can handle a lot of power on its own. Keeping this in view, how do I know if I have a 4l80e? 4L80e transmissions are pretty easy to identify. They have 2 speed sensors on the driver side of the transmission. The early units have no top bolt hole in the bellhousing so you loose 2 bolt locations. The early units also have the cooler lines together near the front of the bellhousing area.Can I put a 4l60e in place of a 700r4? 4L60E to 700R4 Swaping Putting a 700R4 behind an LS series motor is a popular swap option. You’ll find that you need to find a bracket to bolt the tv cable to. If you are going to put a 700R4 where an LS engine was, you’ll need to buy a spacer so that the torque converter will engage properly.
