Answers before you buy

Three of the ones that decide a build. Thirty more — sourcing, cooling, driveshafts, controllers, park release, install — are in the Tech Center.

What does a complete conversion actually cost?

The kit is one line on a bigger invoice and we would rather you knew that up front. A stock 8HP70 or 8HP75 swap lands around $4,000–5,000 minimum excluding install labour — covering the kit, the transmission, accessories (shifter, cooling, park release, mounts and the rest of the miscellaneous parts), a controller and harness, fluid, service parts, coding and tuning.

What else do I need besides the kit?

The transmission, a controller and harness (unless you are on the stock-TCU 6HP28 path), around three gallons of a Group IV synthetic ATF, and service parts — pan and filter, valve body connector seal, input seal. Then coding, tuning and labour.

We sell almost all of it. Where a piece is cheaper somewhere else, we will tell you that rather than quietly sell it to you.

Which controller options do I have?

It depends on the transmission. For the ZF 8HP we stock and sell three: CANTCU, Turbo Lamik and MaxxECU — which one fits comes down to the 8HP generation (Gen 1, 2 or 3) and whether you want the engine and transmission on one standalone ECU. A Ford 6R80 or 10R80 runs on a US Shift Quick 6 or Quick 10. The 6HP28 diesel path keeps its factory TCU, which is that kit’s whole advantage.

Other controllers exist and some are good. We only list what we stock, but we are happy to talk one through.
