I have fitted these on 2 cars and are great. Next oil change you dont need to drop the pan.
Use this kit as it has the better gasket. Same as posted just better gasket.

Also change mechatrons unit, as pan has to be dropped if it starts leaking.

I would suggest getting the Gulf western. Penrite doesnt have a good track record for ZF oil.
If your car hasnt done a lot of Ks say 100k, buy 20L GW, drop the oil and pan , fit mechatronics, install new pan , gasket, filter and mechatronics unit. Then after 1000ks drop oil and refill. Then wait 50k and repeat. After another 100k change the filter.
If you car has done many Ks I recommend a flush..

Fluids which cause Damage
Penrite ATF SYN Automatic Transmission fluid was recommended for this transmission however in December 2010 Penrite released a statement to all customers stating that ATF SYN would no longer cover this transmission. Some workshops who continued to used the oil have reported the industry where it caused clutch squawk on shifting. (Download a PDF Version of Penrite’s Statement Here PENRITE ATF DEVELOPMENTS)
