Is anyone interested in the ZF 8HP transmissions?

Care to elaborate on the technical details? I'm not aware of Haltech having any direct support for the 8HP except sending the necessary information to the 8HP over CAN.

How about some details about the hardware adaption and installation pictures?

What kind of car is it in?

We are collaborating and sharing with halltech. LS3 engine and 8HP are in a 1982 celica rally cross car. We also have the 8HP mated with 900hp Barra engine which sits in a 1980 MB estate wagon

I love the Mercedes wagon!!!

Which TCU are you using inside the 8HP70?

That wagon is silly, lol.

This is pretty cool seeing the insides of this transmission and what you're having to go through to control it. Thanks for sharing the pics

Here is another part that is necessary when doing the Dodge 8HP70 swap:

I should have it next week.

...and that's why it's so easy to steal a Hell Cat. No key needed, pop up the shifter cover and pull the release to put it in neutral. I watch too many youtube shorts, lol.

Today I visited Vic, not just for lunch but to see if he can help with a small project.

I got these paddle shifters from DomiWorks a while back. I was actually going to use them on my GTO, but it seemed more appropriate to repurpose them for the Cougar in anticipation of the 8HP70 swap.



We decided to keep it simple and just mount the paddles to the spokes of the steering wheel. Before taking off the steering wheel I actually mocked up the paddles against the steering when when it was still installed in the car.



This was the chosen location. It puts the paddles at the fingertips but keeps them tucked nicely and the left side one does not interfere with the turn signal stalk.



The location for the holes was laid out and the holes were drilled.



Apparently I forgot to take more pictures along the way, but here is a little video that shows one of the paddles in action.

No TCU. It’s all controlled through halltech.

I am not aware of any Haltech product that has direct control of the 8HP transmission. Do you have some more details, please?

The ZF 8HP swap journey continues as well. Tom is working on prepping these transmissions for us. These two were probably the worst looking on the outside.







But they sure cleaned up nicely!



The really cool part about these transmissions is that they already have a CV cup on the output! If you guys recall, I was basically the one that popularized the use of modern CV driveshafts in older cars. My Cougar has had a dual CV driveshaft since I built it in 2015.



The GTO has had a CV driveshaft in it since about 2012-2013ish...Both driveshafts use a carbon fiber tube.

So when using the 8HP in an older car, the front CV is already to go! I met with The DriveShaft Shop at the PRI show and they assured me that they can build driveshafts for these swaps.
