Here's the summary: 2001 Odyssey with about 136K on it now. I bought it with 42k on it and I'm pretty sure it's the original tranny. In May, on a trip, it did the dreaded check engine light and TCS code thought the van drove normally. Unfortunately, a mechanic cleared the code so I don't know what number. Anyway, I found the thread about the screens under the shift solenoid and linear solenoid clogging. I took them off and, sure enough, the screens on the gasket and the pipes were clogged. I cleaned them out and re-assembled everything. It's been working fine since.
Then today, on the way home on the highway the CEL and TCS lights come on again. Like before, the van's driving normally. I pulled the code and it is, of course, the P0740. What I'm wondering is if there's any hope to testing line pressure (not sure how to do that, but hoping I can figure out how to check it and what it should be) and, if the pressure's good, replacing the solenoids. Here's my question - all the diagnostic data refers to replacing the torque converter clutch solenoid and clutch pressure solenoid. Is this just another name for the shift solenoid and linear solenoid? I'm looking at the parts diagram here http://www.hondapartsnow.com/Page_P...gPicture=False&pageName=AT Sensor - Solenoid (4AT) and all I see are the linear and shift solenoid that I cleaned out last time and two solenoid assemblies on the front side of the tranny called "A" and "B". Based on their position, are these the two solenoids that should be replaced assuming line pressure is good before the tranny is pronounced dead or is that referring to the two larger, and much more expensive, solenoids on top?
