Hi there!
One year ago, when my Odyssey was still under the extended warranty for its transmission, the check engine light turned on. The Honda dealer daignosed code P1736 - "3rd clutch pressure switch stuck open". The dealer cleared the code, test drove the van and determined that everything was fine. Now, one year later, with my car out of the transmission warraty extension, the dealer diagnosed code PO740 - "torque converter clutch system failure" and I was told I need to replace the entire transmission - cost $2,900. I called American Honda and after some discussion they worked out a deal with the dealer to cover 40% of the cost of repair. I believe Honda should cover 100% of the cost of replacement given that the transmission problem first appeared last year under the warranty. Are the 2 issues with the transmission I had related? Can I make a case that the transmission was going bad already last year? Thanks.
