Toyota Tundra 3UR-FE 8HP90 Project

[BlueReaperX]

I have a Twin Turbo Tundra (+1000WHP on E85) that I daily drive. I'm using a Haltech Elite 2500 with a PD16 to run the engine.

I'm currently running an upgraded stock transmission with a high stall converter, but I can't trans brake and it takes 100s of ms to shift. This is limiting my 60' times significantly not to mention it generates a lot of heat when the converter is unlocked which makes me believe it's not very efficient in delivering power from the engine to the wheels.

I was looking to swap in a Turbo 400 or a powerglide but those ancient transmissions are a pain to daily drive so I decided to go the 8HP route.

I got an 8HP90 out of wrecked 2018 Hellcat. Transmission dimensions are close to the stock transmission. Being a truck, I have a lot of room to work with, so no problem there. I'm currently working with Domi-works to develop an adapter. Transmission mount and driveshaft can be done locally.

The Turbolamik TCU I got from 8speed.au with their basic kit, wiring harness and a DCT shifter. I think I have everything I need ordered and in progress.

Once the transmission is mated to the engine and working properly, I will then get the Stage 3 Pure Drivetrain Solution 8HP90 with the high stall converter. It's rated at 2000HP which is overkill for my 1500HP target but will give me ease of mind.

I contacted Turbolamik on Instagram and they told me they think the TCU should work on a Dodge 8HP90. Has anyone here tried it on one or any other 8HP90/95s?

I hope I don't run into many issues with the swap. I'll keep the thread updated as I go through with the project.

I spoke to another customer today and was searching for 3UR 8hp projects and found this. I remember packing your order.

Thanks for the support bluereaperx and dont hesitate to email 8speed if you have any questions regarding setup of the lamik.

Your project is going to be wild and a lot of fun!

No problem and thank you for making 8HP swaps relatively easy.

I actually plan on working on a 3UR/BMW 8HP adapter with Domi-works for my 3UR swapped GT86 but that will probably be later this year or early next year if all goes well with the truck.

I know how you prefer the BMW 8HPs over the Dodge/Jeep ones and most don't make that much torque to require an 8HP90. If you were able to get Domi to make one sooner for a customer, that might push me to work on that swap sooner lol.

My adapter is being delivered as I'm typing this, truck will be on the hoist by the end of the week. Once we figure out the transmission mounts and drivehsaft, I'll shoot you an email for a base map to connect with the haltech ECU and get it rolling.
