Pressure control solenoid B open circuit.
I went to merge on the highway from about a 10 mph roll and put the shifter into first and got on the gas. I've never had the car get confused before, but I think it MAY HAVE only gone down to 2nd. Sensing it didn't do exactly what I wanted, I put it into D4 quickly so that it didn't have to worry about any other inputs I was giving it. However, the first upshift it made while getting up to speed felt strange, almost light a slight bog or bind. I immediately got off the gas altogether until it sorted itself out which it did. I eased carefully back into the throttle but I got the E check transmission. There is no slipping, and all gears work. Going into drive and reverse seem fine, theres just firm upshifts, in alignment with another thread stating that the car is upshifting with full pressure. Its not bark the tires hard, but I'm obviously taking it easy until I get this sorted. Downshifts are fine.
There's only a few threads on this here, and only 2 have slightly helpful info. One of them links to the jag forum. He went to a dealer and they diagnosed a specific solenoid. Sadly, he gave no part number. He did also get a gasket, and filter, so does this mean this item is installed in the valve body? Is this what he bought... "shift solenoid" ?
Anyone with a service manual have more info about what it will take for me to lose the E? Thanks for any help!
