ZF8HP Transmission swap It seems that over the last few years the ZF8HP transmissions have been getting very popular in various vehicle swaps.
This is a poll to gauge interest in adapting the ZF8HP70/90 to a LS engine.
Thanks in advance.

Two days ago I made a trip to the Chicago area to accomplish a couple of things. First of all, I needed to deliver an 8HP70 transmission to my friend Brian. Second of all, I needed to have a meeting with the guys from TurboLamik to nail down exactly how the necessary data from the Holley ECU was going to get to the TCU.
Brian's car is one of the three cars that are being converted to the 8HP70. He has a 66 Fairlane that has been LS swapped for a while now:
This was done today and it really took the efforts of numerous people to get here:
What you see here is a Holley Dominator ECU connected via CAN to the TurboLamik TCU. The laptop on the right is running the Holley software while the laptop on the left is hooked up to the TurboLamik.
The little controller next to the Holley EFI laptop is an engine simulator that was put together by my buddy Carl. It is connected to the Holley Dominator and in its current configuration is feeding RPM, TPS and MAP sensor data to the Dominator ECU. These are the three main parameters that the TurboLamik needs in order to control the transmission.
The Dominator ECU is connected via CAN to the TurboLamik TCU, which is able to read the relevant signals off the CAN bus in order to make its shifting decisions.
This process required Lucas from TurboLamik logging in remotely and actually making new firmware to support Holley EFI. These changes will be rolled into the next release of TurboLamik TCU firmware.
Progress is being made...

Alot of people that have swapped them had issues controlling them properly, if all the issues and bugs are worked out then im sure they would be a popular choice. Ive looked at the dct swaps as well and those things may as well be made of gold for the $$ that they want for the swap (seemslegitgarage).

Also, most of the kinks have been worked out today.

I went ahead and selected I am interested since some day I would like to finish the swap I already started.
it would have been cool if I had finished what I started back a few years ago but that just didn’t happen.
I’m always interested in reading about the latest new options out there.
the 8hp is a better choice than a dct in my option. It shifts as fast or faster and is far simpler to control from an algorithm standpoint.

I agree and the 8hp is much more affordable and comes in many different vehicles. If the kinks are worked out with the turbolamik stuff then id be interested in one for sure. Ive heard they are pretty big, how do they compare to a 4l80e in size?
This guy scrapped his setup and was using the turbolamik setup but claimed there was no support
not trying to hijack or say anything negative just want to clear up the issues side of things.

its definitely not a 'buy it and go' proposition. i got about 75-80% through the design and development of my swap and it really didnt seem like anything completely insurmountable with much more than time and a little more money but i tend to enjoy fairly advanced projects but dont always stay interested. if you can solder, understand electronics, and have some patience i dont see it being too hard of a build.
relying on someone else like turbolamik or another tcu vendor i can see would be a problem. if you need support and cant get it youre stuck. if youre making your own tcu and writing your own code you can just keep plugging along.

Gentlemen,
I appreciate all of the input and the voting. I will have some comparison 3D models posted shortly that will compare the Dodge Charge 8HP70 with both a T56 and a 4L80e. I think there is a broad understanding in the swap community as to what it takes to install a T56 or a 4L80 into the projects of our choice. So having images that compare the 8HP70 to those transmissions will give people a very realistic understanding of what modifications might be needed to the 8HP70. From what I have seen so far, an 8HP70 should fit anywhere that a T56 fits, with minimal if any alterations to the transmission tunnel.

When used in OEM applications, I don't believe that 1st gear is used in cars, but it is used in the truck applications if needed. Cars are generally configured to start out in 2nd gear.
I am not trying to make adapters, but I like what Domi-Works makes.
Is that the YouTube Nissan guys?
