Lastly, the “shift control” parameter may be displayed as “gear command.” These are the most important parameters when looking at TCC judder or TCC-related issues. On vehicles that are not Honda, there will be an Input Speed Sensor (ISS) and Output Speed Sensor (OSS). Output Shaft (CounterShaft) Speed (rpm)Įarlier, we discussed that these are Honda-specific terms however, we can relate these terms and input readings to all electronically controlled transmissions and TCC systems.Īll quality scan tools will have engine speed data in RPMs.Note that when there are fewer parameters that the scan tool displays, the update rate is faster, and the accuracy is much better. That is to say, we can record the judder happening and return to the shop where we can safely watch the event happen. Using our scan tool, we will identify and isolate the critical parameters to view the judder as it happens in realtime. Be sure to let the customer know that it MAY solve the issue, but if not, the transmission would need to be removed! What’s going on in there? You may recommend this as a possible solution if the service has not been performed. If you have a scan tool that can access the program part number, look for part number 37806- RV0-5070 or later to verify the PCM has been updated. The Honda factory powertrain warranty at 60,000 miles gives us a checkpoint to consider when a vehicle comes into our shop. ![]() There is no damage to the torque converter, but because the ATF has deteriorated, it needs to be changed even though the “ATF Service Due” message has not appeared.įurther along in the factory information, it talks about flushing the unit three times! So, in general, a vehicle coming into a dealership under warranty got a transmission fluid service and updated PCM programming. ![]() The problem is typically diagnosed as a bad torque converter. Here are the highlights from the Honda factory bulletin:Īfter the software update, some vehicles, based on how they are driven (extreme conditions), may still experience a judder complaint due to ATF deterioration, and the judder may return. It occurs under light to moderate throttle and is most noticeable when tipping into the throttle after braking.Īccording to Honda TSB number 17-043, the manufacturer says a fluid change and a reflash of the controller may work. The 2014 to 2017 Odyssey models have a common complaint of a shudder (or judder as Honda describes it) between 20 and 60 mph. Keep in mind that you can apply the approach we’ll go through to other models with a torque converter clutch and speed sensors. In this edition of Fun With Transmissions, we’ll check out the Honda Odyssey 6-speed (PYRA) with torque converter clutch shudder concerns by using scan tool data and then looking at the converter’s internal function and valve body operation. 2 passage and 3 passage hydraulic systems. In this day and age there several different styles of converter clutches, captive clutch, multi-disk clutches (think clutch drums). Help!.Everyone has been working on converter clutches for years. Three transmission issues, brake issues, steering issues, etc later I am without a vehicle again. To date, I have been told that because it is over 36 months, (but still under 36,000 miles) it may not be covered under my warranty, and that they cannot provide me with a rental this time. On MaHonda informed me that my transmission was flare shifting and had complete internal transmission failure, and the entire transmission would have to be replaced. On Friday Ma(35,650 miles)I took my van back in to Honda because my vehicle was sling-shooting and having very rough transitions in shifting gears in low speeds 35-45 mph. ![]() My vehicle was returned to me on November 7, 2011. The steering issue and the oil were both repaired again. On Novem(33,946) I took my car back in to Honda because my steering wheel had become difficult to turn, and there was oil leaking from under my van again. They kept my vehicle for another 3 days, and gave me a rental car during this time. I took my van back to Honda on August 11, 2011, only to have them determine that during the initial repair they had broke one of the seals during the install. Upon repair, I got home, and was experiencing the same problem. It was determined that the front torque oil shaft converter/transmission was leaking. On AugI took my 2008 Honda Odyssey (33,2281 miles) in to be looked at because there was a leak under my vehicle.
