Sudden loss of acceleration on the interstate mechanic looked underneath and mentioned the rear main seal on the transmission was leaking and it lost the transmission fluid only option now is an approximate $5,000 replacement with re-manufactured transmission!!!!.
I bought my 2004 Honda Odyssey with less than 79k miles. Now with 107k miles the transmission fluid is leaking .
When traveling down the passing lane of a 4 lane highway in heavy traffic at 60 mph the vehicle suddenly lost power and began to slow as if the brakes were on. Fortunately I was able to pull over to the side of the road without anyone running in to me. Upon getting to the side of the road I noticed that the engine light was on. I put the gear shift lever into park and walked around the van to see if any fluids were leaking. None were. I got back into the van to see if it would move. It finally did after moving the shifter from p to d a few times but it did not have the power and did not shift correctly. The code that turned up on my mechanics scanner showed that the transmission had slipped and would need replacing. I called Honda and they said there was nothing that they could do for me eventhough there has been numerous issues with these transmissions. The only recall they acknowledge was the fuel pump for my van. The outcome of the event could have been much more serious and I feel Honda is just turning a blind eye to this. If this caused a serious accident I question what they would say after a lawyer gave them a call. They should have at least attempted to negotiate a deal for a new transmission. This will be the last time Honda does this to me. I have owned many gm vehicles with more mileage and never had experienced a transmission failure. After spending over $3500 on a rebuilt transmission I don't believe another Honda will be in my driveway!.
