Specifications Preliminary Note. 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. America's Most Wanted 6.4L SRT8 Hemi + 8HP75 Transmission Swap - Installed - JL AT-These are installed ONLY, and WILL NOT be shipped. WE ADVISE CALLIN.

ZF 8HP-75 allows also to have of an additional set of gear ratios with spreading 7.813 or 7.071, while in ZF 8HP-70 is only 7.071. For example now first gear can be 5.000:1 or 4.714:1, in 8HP-70 can be only 4:714:1.

More info and pictures coming soon
The PCM from the converted Jeep will be needed to complete the engine programming. A ship here ship back system will be used to make this an easy step.
Gladiators have different engine frame mounts than the 3.6L Wrangler and require welding in new frame mounts.
*These contain conversion parts only. OEM parts and engines must be purchased separately.
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. 4 A torque range from 300 to 1000 newton meter makes the 8HP the perfect partner for all rear-wheel-drive and all-wheel-drive designs. 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. Although the 8HP features 2 more speeds than the extremely successful 6HP, the dimensions have remained unchanged and the weight was even reduced by 3% to 87 kg (transmission modular system 8HP70) including oil. At the same time, the total transmission ratio spread of 7.0 ensures that the engine is always in its optimum operating range. 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. In the premium and mid-size car range, the optimized 8HP product family enables the average fuel consumption to be cut by another 3%. 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 (3-8 cylinders) which will determine the trend of the years-to-come.
