This is a 2008 2.5 XT5-speed AT has two torque converter turbine sensor signals. These are not the vehicle speed sensors.
Based on logs that rasterman shared with me some time ago, the turbine 2 signal should show up in RR at all times; that is, whenever the engine is running, transmission is in gear, and the car is moving (wheels turning). The turbine 1 data shows only when the transmission is in 4th gear.
I understand from the FSM that the turbine 1 sensor can be replaced on its own, but the turbine 2 sensor is part of the valve body.
What fault code are you getting? P0715, P1710, or some other one?
What are the symptoms?
The two versions seem to be substantially the same. There are actually two sensors mounted to the valve body on either version of the transmission, here's an example of the early type: http://legacygt.com/forums/showpost.php?p=2119276&postcount=82008 FSM is different. The wiring diagram shows the rear VSS with a connector and the front vehicle speed sensor as part of the control valve body, as well as the two turbine sensors. See jpg attached.

Looks like I was wrong about that at least twice.
That would probably be the P1710, which interestingly is the same problem as in the legacygt.com post that avk provided in post #11 above. (Here's the full thread link: http://legacygt.com/forums/showthread.php/installed-ipt-vb-got-cel-p0700-p0710-98446p2.html). That would be an example of someone experiencing a failed turbine 2 signal.This is a 2008 2.5 XT
I don't recall the specific code. I didn't realize FreeSSM would dump the data when shut down. but it was no signal from Turbine 2 was the description.
Symptoms are a very hard 1-2 2-3 shifts and then faults and stays in 4th gear.
I need the trans control units pin out so I can at least make sure it's the sensor and not the control units input before I buy a new valve body.
Let us know what you find. If it turns out to be the wires, perhaps take some photos and post them here so that others reading this thread in future won't have to look elsewhere.Thanks OM,
That what I needed.
It would be so awesome if this turns out to be a loose wire, time to drop the pan again.
Yes, it's not clear, but for test 6 it says connect all, so presumably in 5 the transmission is not connected yet. The 5 V is as specified. There's no spec for the voltage on pin 6 with the tranny connected so no idea if the 1.76V is correct.test 5 =1.76v but if I disconnect the the transmission connectors it is 5v. unsure if I was supposed to reconnect after test 4.
