Ls tcc hook up 4l80e transmission, why the 4l80e transmission replaced the th400

The gear ratios are 2. First you need to find wich wire on the tachometer is the coil signal.

4L80E Torque Converter

MERGE already exists as an alternate of this question. Finally plug the other wire s to a 12v source who works only with the key at the RUN position. Take the black wire and put it on the ground of a 9V batterie then try all the other wires on the positive side of the battery until the RPM move.

I would suggest you try to find the manufacturer of your tachometer on the web and check out their support site and email them if needed for your particuliar vehicle. The trans has experienced multiple minor upgrades over the years, with the newer boxes being a bit more attractive, but all the versions can be made to work well in a performance application.

So its best to get the info from the pro's.

From 4L80E, the 4 indicates that the transmission has 4 gears. The 22 years of usage is a testament to its robustness and strength. Pin out for Monte Carlo instrument cluster connector.

What would cause the temperature gauge to go up? Answer It hooks up to the transfer case. Most of the concerns about rL80E transmission revolve around the need for electronic control.

It hooks up to the transfer case. The bolt patterns are different. Chevrolet Performance offers multiple transmission control systems for both factory-style EFI setups and carbureted LS engines, as well as 4L60 and 4Lbased performance automatic transmissions.

I also want to note that connectors on these things are modular. Finally, the E in the name indicates that this transmission is electronically controlled and actuated.

However, the torque converter bolt pattern and pilot length is different on the LS transmission applications. The other will be in its original location on the end of the transfer case.

We did some research on some of the more important aspects of performance uses for this transmission. The connectors and pin outs is pretty well documents here.

They are designed just like our LS fuel injected controller kits in that they are pre-calibrated to function after they are hooked up and plugged in.

You have to get it connected to the PCM. This transmission is significantly heavier than the 4L60E with a dry weight of pounds. On a vehicle without power brakes, the vacuum port is normally plugged with a screw in plug. Will a bolt up to a transmission hooked up to a slant 6?

You should take your car to aprofessional to ensure that you don't overheat your car. Make sure that the coolant is full. It brought both overdrive gearing 0.

Between the two options, a flexplate swap using the original converter will be cheaper, but considering that the new engine is likely going to have a very different powerband than the one coming out, a torque converter with a more aggressive stall speed is likely to be the more desirable way to go.
