The setup of this system allows only 450 hp to be supported before it finally gives way to breakage. Finally, the Third gear is divided between two shafts, where 60 percent is concentrated in a small inner shaft that is susceptible to breakable. On the same note, the inner shaft which is driven directly off the engine plays a role in controlling the Overdrive. This system’s mode of operation is one where the outer shaft controls the First, Second, and Reverse gear clutches using the torque converter. Another bone of contention is its complicated twin input-shaft system. AOD moves between the Drive and Overdrive in traffic which does not really speak of safety. In order to understand what the AOD can achieve with some upgrade, it is useful to know what it can currently do and to what extent.įirst, even the best Ford AOD transmission screams unreliability and that can be attributed to several reasons. So with all these benefits, what’s the way forward? Read on and you’ll soon find out. You can also look forward to a beefier intermediate sprag on the AOD. You may be wondering, how is that an advantage over the Turbo 400? The thing is, the thinner gear pump helps to reduce the drag for particular line pressure. The AOD’s pump gear in comparison to that of the TH400 is thinner. The difference between either comes with several benefits but this time around, the AOD is the clear winner. On the contrary, you’ll find two sets of planetary gears as well as two carriers on the TH400. Not to burst your bubble, both sets of the AOD’s planetary gears are embedded in a single carrier. Sets of planetary gears in a single carrier: You don’t believe us, then compare the 6 3/4 inches of the TH400 with that of the 5 3/4 inches of the AOD and then do the math.ģ. The Ford AOD Transmission is 30 pounds lighter than the TH400 because it features an aluminum valve body and also offers a lightweight center support section.Īnother thing to point out is AOD’s rotating mass which is 4 pounds lighter than the TH400 and its diameter which is 1-inch trimmer. AOD’s lighter weight compared to the TH400: If these features are taken advantage of, then it can potentially offer the level of performance more than what a person would have ever believed it could.ġ. Unarguably, the TH400 is the king of performance transmission, but a closer look at the Ford AOD shows that it comes with more than it lets on. Nonetheless, it wasn’t all bad things since there are features that will enable the Ford AOD to become a bulletproof transmission some car fanatics have been talking about all the while. The Ford AOD transmission shifting problem, therefore, gave it its unreliable performance reputation. The result was at the expense of your bands and clutches. First, you’d need to engage the lever into Drive before moving it to First gear.

On the contrary, one could still access the Second gear in a manual but that came with a headache of its own. While many have pointed out that it was in a bid to curb the cost, it still had a huge effect. For starters, it uprooted the Second gear in the shift pattern which left the latter dwindling in the gory land without remarkable performance. The Ford AOD transmission was evident in cars like the Mustangs, Fairmont, and LTDs around 19, and it was quite unique even though not in a really good way. It may also be worthy to note that they are not just all about talks because certain manipulations to the AOD can turn it into a sturdier transmission with the benefit of Overdrive which can be a strong competitor with the TH400, and maybe even overtake it.īut why the Ford AOD, one may ask? We’ll get to that shortly! The Advent of Ford AOD Transmissions They are even confident that the Ford AOD transmission can be the performance transmission of the 21st century. Nonetheless, a good number of car fanatics who have been in the game for decades think otherwise. However, car enthusiasts may be quick to settle for the Turbo 400 due to the popular belief that it is the king of performance transmission. There is the Ford AOD (automatic overdrive) transmission on one hand, and the Turbo 400 (TH400), on the other.
