Converter output speed. I should have picked up on that from your previous post. See attached.I’m sorry Nige. I gave you the incorrect code. It’s 672-2
I think he has ET. It might be worth monitoring the signal from the TC output sensor when the shaft is spinning in neutral.one last thought if drive shaft isn’t turning I don’t think you would have a signal from torque output sensor
I had a quick look under LAY-prefix for this machine and nothing popped up. Need to dig deeper....turned out to be a bad position sensor on transmission control that’s just a thought that pops up in my head
Ok. So the shaft doesn’t spin long in neutral at all but for the short time it does, it doesn’t show torque converter rpm.It might be worth monitoring the signal from the TC output sensor when the shaft is spinning in neutral
If you look at it with ET AFAIK the sensor should register a zero RPM reading when the shaft is not spinning. FMI02 is "erratic, internmittent, or incorrect" data. Are you seeing a wildly varying TC Out Speed value (for example) at Low Idle when the engine RPM should be somewhat stable.?But a question I’ve asked a few local guys without getting an answer, is the code popping up because the shaft isn’t spinning or can a faulty speed sensor cause it to not spin?
That may turn out to be the case at the end of the day but, again IMHO, you need all the external factors corrected before condemning the transmission as somehow defective internally. You'd be kicking yourself for pulling a transmission that after removal was found to be operating correctly.Local cat dealer thinks I’m focusing to much on the electrical when it’s probably mechanical prob in the cv.
in ET it shows 0 rpm even the short period that’s it’s spinning initially at startup. So yes, there could be something up with sensor… but they’re telling me that shaft should always spin if the engine is running. If not, then in their opinion it’s either mechanical in the torque converter or pressure not getting to the torque converter or bypassing inside. They don’t think it’s something to do with transmission anymoreIf you look at it with ET AFAIK the sensor should register a zero RPM reading when the shaft is not spinning.

I didn’t read these last 3 msg from you guys till now so didn’t actually get a chance to look but speed sensor was reading as wellIf you rev the engine to full speed in neutral what is the rpm at.
I was speaking to it being in neutral then it should always turn…What, even if the transmission is in gear.? Sorry that’s BS. Engage any gear at engine Low Idle RPM and that shaft should stop dead.
Yes I did fill with this oilDid you fill the tranny with the TO-4 oil in (Petro Canada.?)
I intended to change it after a bit of use so I will also cut it as well. But no, we don’t do oil sampling typically.Next suggestions. 50 hours on the tranny, change the filter and do a filter cut. Inspect for particles.
Throw the gauges on it again if you feel inclined/have the time.
Do you do oil sampling at your company.?
If you did oil sampling you could do a filter change + cut and take an oil sample. No need to change the fluid unless in the highly unlikely event that the oil was somehow contaminated. Think about it with respect to cost and time.......Yes I did fill with this oil

We didn’t touch the pump seeing the initial pressures were ok, and no we didn’t bother with cooler either.what did you do regarding the transmission pump and the cooler.?
