P38A torque converter lockup

The ATF doesn't "Stay" in the converter, it circulates around the box, that is why people recommend you fill it, run for a while, then change etc etc..

A good way to do it IMO

That's why i disconnected the oil cooler and collected what came out, while continually adding oil
 
Definitely something not right, getting lockup far too soon and just now with sport!? mode selected seemed to be hunting, hard to tell but seemed to select 2, 3, 4 and lock, back to 3, by which time I've run out of road and need to slow down

The box often shunts between 3 & 4 on an incline, I hold in 3rd with the gear lever when it does that. It should not do it on the flat.
Do you get any over revving as it shifts?

I don't normally bother with 'S'illy mode, it didn't over rev as per a false neutral or anything like that, just hunted round a bit.
Is there any kind of adjustment or is it all electronic? Could it be confused with a different driving style to normal?

It's all electronic, no adjustments that I am aware of. The shift patterns are not very good IMO. For example, climbing a hill, if you give it a bit of welly, it will drop to 2nd and rev it's nuts off, then immediately upshift to 3rd. I have 2 cars that do the same, so I have to assume it's normal. There are other unsatisfactory happenings that appear to be normal and driving style certainly affects things. The 4.6 has a sort of learn mode which alters settings to driving style, I have no idea if it's effective as I have never been near a 4.6.

Thank you :) i shall assume it's a feature of the green oval and drive accordingly. Like you say, help out along by holding 3rd manually. There's a reason you don't need to press the button to do that!
 
It sure as hell does not come out when you drain the sump.
I didn't say that it did.

4.1 came out of my sump ;)

The new stuff was instantly contaminated, 4 changes later and it's as clean as it'll ever be ;)

Much safer in my opinion than removing cooler lines and potentially running the box dry. ;)
 
The difference between the diesels shifts compared to the petrol is the shift times and behaviours.

the v8's change much sooner as they have something the Diesel doesn't have, TORQUE!! ;)
As such the shift point are in the right place ;)

Under light acceleration the V8 should change at around 1700rpm -2000rpm lockup 4th should happen around 45mph..

The shifts should be almost unnoticeable, atleast with mine they are.
