| Acura's supposed to be installing these for the transmission recall, and I'm just wondering if anyone know what these kits do. Sounds like something that they put on the atf return line to increase flow, but how's this done? Anyone know or any guesses? |

Nope, just a guess it is what it sounds like. A jet to direct more fluid flow at the shaft that runs too hot under certain conditions. They are doing this obviously, because it can theoretically cause an accident if it the gear locks up the drive train while driving.
If not for that possibility I doubt they would do much. There may be more common tranny failure modes that exist in the MDX, but are not likely to cause a catastrophic event.
They said the actual number of 'breakdowns' due to this failure are 10 out of 600,000 so far. |

| I'd like to know too. Perhaps Tim can post the details on the install process, I believe the instructions were sent to the dealer this past Friday night. |

I second that emotion, I also hope Tim or someone can post more info on the install. Is this just screwed in some how? Drilling needed? Fluid removed/replaced? How do they get to inspect the gears without disassembling the case?
Honda/Acura sure is unnerving alot of loyal owners with a series of transmission issues. I hope they consider extending the warranty.:1: |

Well, it did say they are inspecting the shaft for signs of overheating. Not the gears themselves, and doing this through the hole for the speed sensor.
If the shaft is overheated, then the risk of potential gear damage exists. If the gears are already damaged, you will know it. No inspection required.
There are all kinds of devices, borescopes, fiber optic viewers, etc. that can be used for this purpose. It is nothing that exotic.
More interesting will be the device they install to spray (?) ATF on to the area to provide additional cooling. |

The oil jet kit essentially t's another line off of the line from the filter to the pressure line that runs along the top of the transmission. That new line will go into a new fill plug with an o-ring seal that will shoot oil directly onto the gear they are looking at on the inspections and pretty much lubricate the upper half of the transmission's gears and shafts.
When you are doing some long highway cruising, the transmission in in 5th gear, the torque converter is locked, and the solenoids keep line pressure low. In other words, the transmission isn't very busy. When you're in city traffic, you're going through the gear range, different solenoids have to acutate sending line pressure through different orifices, and lateral and accelerative forces "slosh" the fluid around as well...which does an effective enough job of getting fluid to the upper half and preventing those gears on the countershaft from going through oil starvation and burning up.
That about explain it? |

Yes, thanks. In your opinion, Rob, how effective a solution is this jet kit? |
