I suspect he means transfer case and not torque converter.

Correct - Transfer Case was drained and filled with new oil - sorry should have been more specific.

The Torque Converter and the cooler in the transmission (unfortunately) retains some of the old fluid, you can never drain it all out.

Full refill takes 9.5 litres, so far I have been able to drain about 6-7 litres out (basically left the drain pan underneath it for a week while i was at work and while the valve block was out). So this is why i bought 20L to allow me to flush until im reasonably sure that Ive got 100% new fluid in the unit.

My understanding of the fill process is that the engine has to be running, the thermostat has to open to allow fluid to flow through the Torque Converter and cooler, this opens at between 30 and 50 deg C. Then flush through the cooler hoses into a drain pan until new fluid appears, then reconnect cooler hose and fill transmission to fill plug.

So I asked Dr. Google what this mechatronic sleeve thingy was. I ended up at YouTube with a transmission service and mechatronic sleeve replacement on a Territory. For something with mechatronic in it’s name the sleeve was a bit underwhelming. But I digress. The mechanic used Dexron 6 with Ludeguard Platinum additive to refill the transmission.

Terri's use the ford ZF copy so a slightly different box, no idea how much they differ.

Lifeguard was the recommended oil but in the mechanics words, “lifeguard oil is very expensive”.

Then youd best be prepared to invoice him for a trans rebuild... he is NOT doing himself or more importantly the customer any favours by ignoring industry and manufacturers advice...

by then the statutory warranty period for a repair will be over and he won't give a rats

Will post the results once back in the car and running.

Hi Eric, couldn’t find a post where you communicated how the gearbox functioned after performing your maintenance.

I am considering pricing up the parts to do the same style of work.

I have owned my TDV6 LR3 for around 18 months and dropped the transmission pan, changed the oil and performed a steel pan conversion.

The shudder I had at around 90k/hr disappeared altogether but the first to second gear change has left a lot to be desired after changing the oil.

My car has 273k on the clock (30k by me).

Thanks 👍
