Yes but much reduced. I think it's more to do with holding the higher revs. It doesn't drop into neutral unless going very slowGot to be honest, I've had very few issues with that 'box - is the behaviour the same in 'S'?

Then the torque converter is locking up OK, back to looking at speed and torque values - have you checked the output speed sensor is reading correctly?Yes but much reduced. I think it's more to do with holding the higher revs. It doesn't drop into neutral unless going very slow
i havent, i'll plug SDD in tonight and have a look. presume its called something obviousThen the torque converter is locking up OK, back to looking at speed and torque values - have you checked the output speed sensor is reading correctly?
What reading should i be looking for, how do i know if it's good or bad? And which speed sensorThen the torque converter is locking up OK, back to looking at speed and torque values - have you checked the output speed sensor is reading correctly?
As said, "output speed sensor". With live data and the car moving it should produce a signal but since I know feck all about the L322 diagnostics where it will appear and what it's called, I don't know.What reading should i be looking for, how do i know if it's good or bad? And which speed sensor
That would/should set a DTC, if the value is incorrect but still within the valid range, that'd give symptoms but no DTC.If you had clutch/torque slip you could have an input/output sensor correlation fault possibly?
It was supposed to have been done by the guy who did the oil changeHave you had the adaptions reset?
That does not sound right to me.I didn't see a live data selection called output speed sensor but saw a few others.
Transmission output shaft speed was interesting, it was at zero apart from a spike when starting and a spike when stopping.
There was transfer box motion sensor voltage which went from low to high, the switch happened before i came to a stop
In the higher gears, with high throttle inputs it seems fine, there would be greater leakage and bigger symptoms?8hp has a reputation for issues in the valvebody usually pressure leaks that can cause the trans to act erratically.
The priming valve in the valvebody losing fluid pressure is a favourite that can cause it to shift poorly.
That's what i thoughtThat does not sound right to me.
No signal to indicate that the output shaft is turning would certainly confuse the ECU.That's what i thought
Don't do that! The only time that should be done is if a software change requires it or solenoids have been replaced, doing so on a 'box that has had no work done can lead to some pretty bad shifts, some 'boxes never achieve their previously 'acceptable but could be better' shift behaviour.Have you had the adaptions reset?
