I've been having some jerkiness in my 2000 Alfa 166 3.0 Sportronic, caused by the transmission. In experience, the first thing to do is to replace the transmission fluid, even though Alfa states the fluid is for life, when I replaced the fluid it worked smoother and the slippage was reduced.

WARNING!!!
The trans is the ZF 4HP20, used until 2002 (to my knowledge in 2003 the transmission was replaced to Aisin's 5 gear auto), the Sportronic 166 3.0. The fluid is a special, NOT COMPATIBLE with Dexron III ATF. The correct one is Esso ATF LT71141, which can also be bought in a Peugeot dealer (part no.: 973622).

Procedure to replace the fluid:
1-Remove the plug in the differential case (Allen wrench 12mm), to fill it and to know the maximum level.
2-Remove the bottom plug from the trans case (Allen wrench 8mm). Make sure you have a recipient with a capacity of at least 3.5 liters, beneath the plug.
3-After in drains,replace the plug under the trans case (8mm)
4-To fill it, I syphoned the liquid using a hose.
5-Replace the other plug (12mm).

The fluid comes in 2L bottles. The trans takes aprox 3.5L.

The trans actually takes about 7 litres, its just there is no way to drain it fully unless you flush with something else.
I've had fully synthetic Dextron 3 fluid in for about 10k miles and its fine.

Dear Alfa 166 3.0,
I'm getting prepared to change oil in my ZF auto box. I understand that though the box is "service free" in reality the oil should be changed from time to time to prevent the complete overhaul of the box. I consider your description of the fluid change precedure (steps 1-5) very useful and clear, but I have one question about the plug:confused: :confused: in the diff case:

1. Is this plug the one marked "3" (red colour) on this French site on Citroens (but same ZF auto box)? link: http://www.3000fr.com/forum/viewthread.php?tid=2437

2. How did you reach it? From the top (then the air duct & may be somethin else has to be removed?) or from under the car (then the twin exhaust pipes, the power steering rack and the black cross-member stand in the way!)

drain its easy to get at both the fill and drain plugs.
Alternatively you can drain and fill from the oil cooler pipes, but you still need to release the drain plug to check the level on fill up.

n accordance with spare part number of vehicle manufacturer:

Esso ATF LT 71141 in acc. with ZF Order Specification ZFB 838
=>Audi Oil No. G 052 162A1
=>BMW Oil No. 8 322 940 7807
=>Citrogen Oil No. Z 000 169 756
=>Jaguar Oil No. JLM 20238
=>Mercedes Benz Oil No. A 001 989 2203
=>Peugot Oil No. Z 000 169 756
=>Porsche Oil No. 999 917 547 00

I have just read an article where they describe having a 20l drum of the correct oil fixed to the oil return pipe and a big drum to catch out flow then tutrning on the engine to let the gearbox suck in new stuff and pump out old. It ensures that you have a COMPLETE change of oil, with no old stuff left in the torque convertor.
Might give that a go next week!

Thats a good procedure. Some call it the ''Gibbons method'' I have done it on a few Volvos.

Proper transmission specialists have machines that will completely flush whats in the torque converter, this method does the same. It's just that on some cars you cant perform a Gibbons style flush hence the need for specialists.

Is the "Gibbons method" also known and "dynamic oil change". There's quite many places that offer that. Is it possible (accessible) to do it with 166 3.0 autobox?

Is that not what CrispDust was getting at? I assumed so. :nerd:

I guess it depends how easily you can access the oil send/return lines.

I haven't had a look yet but I'll be getting round to it this week.
