![]() Obviously they have the system optimized for high mileage but I think they programmed the fuel delivery very weak after the shift and this is the stumble I have experienced. I feel like it is an engine ECU programming issue. The cylinder disable (ECO mode) clearly makes the motor run a bit rougher and the power is obviously cut way back but the effect I have experienced tends to be in standard mode and only after the shift has taken place. I don't believe its from the ECO mode as I don't see the ECO light come on till I come to a steady throttle and speed. ![]() Like it just falls off the torque cliff and you have to wait for it to work it's way out of it. In other words the van will accelerate and then as it makes the shift the added load on the motor makes the engine stumble a bit. I drive the vehicle nearly 100% of the time and am very tuned into how the van sounds and runs.Īnyway the shifting between 1-2, 2-3, and even some times between 3-4 and 4-5 tends to have what I call "a power loss". I have a 2011 Touring with the six speed as well and notice this at very light throttle application. Stay tuned and share your similar experiences.Ĭlick to expand.Exactly. In addition, I have already been told that they are forwarding my case to a team to look at the option of a buy-out or vehicle replacement so they are taking this seriously which to be indicates they did not like at all the initial data captured they were sent when my local service tech took readings when the transmission was stuttering which is very easy to recreate and seems to be getting worse. ![]() I can tell you that my regional case manager already told me it would be another week to analyze all the records and they might even dispatch a corporate service engineer to Leith Honda (which is an big Honda dealer with an exceptional track record in their service dept) in Raleigh, NC to look at my van to look at everything going on. I will keep you all posted, but please go to your dealer and also call Customer Service and get a Regional Case manager assigned as this is not an easy fix or a "it is just built that way" thing at all. The current thinking from lead dealer techs and Honda engineering is that it is not necessary the transmission but could be engine, computer or other related system that is affecting transmission shift performance. Two things is that 1) That fluid was captured and is being sent to them for analysis and 2) It had zero impact on the problem. One of the recommendations was already acted on by my deal when Honda engineering asked them to drain the transmission fluid and replace it with new. In addition, I called and opened a case with Honda Customer support and now have a Regional Case Manager assigned to my problem and I STRONGLY encourage everyone who is experiencing this gear change "shutter" to do the same. My Honda dealership engaged Honda tech support / engineering to help diagnose the problem. I have a bit of an update and I can assure you this is not normal.
