For the 8-speed automatic transmission, ZF set out to design and develop an entirely new gear set concept. The result is a revolution in transmission design: a transmission concept with 4 gearsets which requires only 5 shift elements — of which only two are open in any given gear. The 8HP also requires no more than 3 multi-disk clutches and 2 brakes, which allows it to achieve a greater degree of efficiency than other concepts.

As a result of the fact that only 2 shift elements are open per gear, drag losses in the transmission are sustainably reduced. This effect is supported by the use of a new parallel-axis vane-type oil pump.

From the lower midsize segment to sporty luxury cars, and in every type of SUV and offroad vehicle — its revolutionary design is always an efficient and economical solution.

At the same time, the total transmission ratio spread of 7.

This translates into improved acceleration and reduced fuel consumption. Based on a really successful product, it combines dynamics and comfort with improved efficiency — also with regard to the costs. And it is ideally equipped for even stricter fuel consumption and CO2 emission regulations. CO2 emissions decrease to the same extent. These potentials can also be completely transferred to hybrid drives. Incidentally, additional savings potential by a further optimized startstop function is not yet included here.

To achieve these innovations, ZF engineers have optimized some details. Thus, the reduction of drag torques and engine speeds further reduced the already very low power losses. Essential success aspects are the higher transmission ratio spread and the reduction of system pressures in many areas. Another factor is the multidisk separation of the brakes. Furthermore, advanced torsional vibration dampers enable a faster bypassing of the hydrodynamic power transmission and therefore further reduction in speed.

Thus, the new 8HP is perfectly prepared for use with the new engines cylinders which will determine the trend of the years-to-come. Products for Cars. Share Contact. Share this page on:. Get in touch. Innovation by reduction: efficiency, perfected With the development of the new 8-speed automatic transmission by ZF, the focus is not on the number of speeds but rather on the minimization of fuel consumption.

The new 8HP 8-speed automatic transmission, which was designed to be more lightweight, sets new standards for flexibility, efficiency, and economy.Future development will see two four-wheel drive versions available, with a version destined for Volkswagen Group applications using a Torsen centre differential. This transmission is marketed by Chrysler under their own brand name, the Torqueflite 8.

Efficiency improvements over the original design include a wider ratio spread of 7. Refinements were also made with respect to vibration. Major improvements are total spread of 8.

There are several options in maximum torque available, also the gearbox is available with mild hybrid and plug in hybrid options: With 15 kW and NM supporting boosting and recuperation in combination with 48 Volt technology up to 90 kw and NM for usage with higher voltage. Below is a table of reference gear ratios as provided with the ZF 8HP transmission, though actual implementations may differ depending on the tuning and specifications of individual vehicle manufacturers such as BMW and Audi.

Differences in gear ratios have a measurable, direct impact on vehicle dynamics, performance, waste emissions as well as fuel mileage. From Wikipedia, the free encyclopedia.

Instead of doing a rebuild or swapping to a manual it's my daily and I live in busy NYC I thought of doing a zf8hp45 swap from an e84 x1. I can't confirm this, but it seems that the e90 and the e84 are essentially the same chassis, the e84 just having an suv body sitting on it. I came across a thread where this swap was discussed in Australia in early but they never followed up in regards to whether it worked or not.

I would love to get your insight on this project, I am pretty set on making this happen but my knowledge of electrical vehicular communications and how that sort of stuff works is very limited. I'll be posting this thread on the other forums as well. All feedback would be really appreciated. Oct 18, 8, AZ. All of which are the same transmission, the name varies depending on which catalog you are looking at.

The 6HP19 is a first generation transmission alongside the 6HP26 which is the one Nizpro is known for upgrading. Regarding the swap, you're in for some interesting work because those transmissions are installed in BMW vehicles which use the FlexRays powertrain communication system, so an interpreter box would be required.

You want to speak to Bimaxtremeretro as they can do this, they just need someone's car and money, in Australia. Thanks for your reply-- I have seen the thread here before with Bimaxtremeretro and sent him a message, I'm still awaiting his response. NYC is very far from Australia, unfortunately, but maybe he can shed some light on the situation.

Keep us updated, you have a guinea pig in south florida now. No one has done this before and seems that no one wants to get into it. I reached out to him about 2 weeks ago via PM, no response yet.

Apr 16, 3. I am also looking into swapping a better transmission in my xi. Anyways try this place, its in Europe, they've done some random and crazy ZF8HP70 Swaps so they probably know a thing or two.

I contacted them and they said they swapped in a zf8hp70, the beefiest zf8, by using an adapter plate for the bell housing and a custom tcu.Two words: shift quality. All one-gear and two-gear shifts use just two shifting elements: one opens, another closes.

The 8HP also executes certain multigear shifts in this manner; witness the leaps from sixth gear to third and even eighth to second.

The 8HP transmission comes only in longitudinal form for rear- or all-wheel-drive vehicles, and we prefer it immensely to ZF's transverse alternative, a nine-speed.

Insome 3. It can accommodate a maximum torque output from as low as pound-feet up to It is compatible with a variety of all- and four-wheel-drive systems, such as an integrated center differential or a two-speed transfer case.

The ability to swap the torque converter for an electric motor, as BMW has doneallows automakers to develop hybrid variants with minimal changes to the drivetrain. And the commonalities among all 8HP gearboxes allow companies to share core elements between vehicles as different as the Dodge Demon and the Ramminimizing development costs.

Has the dual-clutch transmission met its match, then? But the DCT finds refuge in supercars. The added length of a torque converter can be prohibitive in a mid-engine architecture, and precise launch-control programs provide an advantage in acceleration. But for just about every other vehicle, though, it's hard to argue that anything can do the job better than the ZF eight-speed. Buyer's Guide. Type keyword s to search.
