Gen4 2020 SZ5 Automatic gearbox

I recall some previous discussion regarding draining/replacing automatic gearbox fluid and that there is no drain-plug rendering it impossible to completely drain all old fluid. Is there a removable gearbox sump and filter as in my BMW X5 or some other way of draining all fluid? I am told by my dealer that it is a 'sealed for life' item and will never require changing unless the gearbox is removed for repair..?? My intention is to replace fluid at say 50k as I have done with previous cars, but how?

It's the same with most autos.  You can remove the sump and the filter, but only a litre or two comes out.  The total capacity is usually about three times that.  You can do several changes a few days apart - three changes of 1/3 of the fluid would replace a majority of it - and try to suck some out of the dipstick tube (if the Gen4 has one) and ATF cooler too.  If you can get half of it out, two changes should suffice.

Check your owner's manual, the fluid is replaced every 99,000 miles or 18,000 under severe driving conditions.



The Jimny has an old style torque converter/planetary gear automatic transmission, the bulk of the fluid is trapped in the torque converter and the only way to get it out of there is to disassemble the transmission, your options for a fluid change are limited to multiple drain & refills if you're doing it yourself or take it to a specialist with a fluid exchange machine.

You need to find a workshop with this equipment.

Try an independent Land Rover garage because the oil in some auto boxes has to be pumped out.
