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.

- The ZF 5-speed transmission replaced the BorgWarner T-19 and was paired with the 6.9L and 7.3L IDI as well as the Ford 7.3L Power Stroke diesel engine up until the 1997 model year. While a fairly reliable transmission, the ZF5 has been known to have problems with the hydraulic clutch system, causing grinding of gears and rough gear engagement.
Zf 5 Speed
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.

Ford starting using the ZF-S547 in 1995 to 1998 utilized the S547M was utilized between 1999 to 2001, this transmission is rated for 470 lb-ft. input torque all gears are synchronized. The particular unit came in2 different ratios wide and close ratio variations. The close ratio editionis utilized in F-Series trucksusing a 7.3 Lt diesel engine and a gross vehicle weight over 8500 lbs.

Fiveof the extremely common problems in ZF-S547 manual transmission failurestend to be:
Noiseonacceleration and speed, ZF-S547 Noise upon deceleration
This problemmay betracked to failure of the pilot bearing in the flywheel, alsoexamine to ensure that the fluid level is correct. Youshould alsoexamine the bearing between your input and main shaft. Rough and excessive wear on therear bearing on the output shaft. Noise can even becaused bysubstantialuse of needle bearings under main-shaft gears.
Hard to get to get into gear ZF-S547
1st, 2nd and reverse might beattributed tofailing clutch. And or failureof your reverse syncro ring/slider.
Grinding going into gear ZF-S547
Syncro ring or slider wear, excessive bearing wear allowing shafts to moveaway from design boundaries. An additional common problem is excessively worn shift housing or shifter, each of whichcan replace by re-manufactured componentsby Midwest Transmission Center.
Popping out of gear ZF-S547
May bebrought on by worn syncro slider and orperhaps shift lever maladjusted. Worn input bearing as well as shift shaft.

This issuemay bebrought on bythe examples below: Shift fork pads missingor with abnormal wear, damaged fork or slider grooved.
The ZF-S547 transmission can alsoreceivedamage to the front case 1 / 2 (bell housing) and maybe the rear extension housing because of a damaged drive shaft, bent, out of balance, excessive wear of u-joint or yoke. At the very firstsign ofvibrationwe suggestthat you have the driveline high-speed balanced. Malfunctionof your dual mass flywheel can alsocrackthe actual bell housing portion of the case.
