Tranny fluid

[jagvette]

OK as you guys were so helpful on my previous question here is another one I have a 2006 S Type R I am changing the transmission

filter and solenoid block then refilling with fluid (yes I have done S Types before) BUT I keep reading I should

use Pentosil fluid number 1 does anyone know if I must and if not and I use regular ATF ?

 

Thanks in advance.

I believe the later S Types use a ZF gearbox so you should be fine with a Dexron 6 fluid or equivalent.

Is there a reason cited for the use of Pentosil #1?

[jagvette]

just surfing the internet and it seems that was the one to use, and yes my car does have the ZF box

I'd have a look online in your home area (it says non-UK so no idea where in the world you are) and find a Dexron VI compatible fluid and use that, especially if you plan on periodic part-changes or full changes to maintain it.

A quick search revealed that Pentosil #1 is a "life-time fluid" so is likely to be more expensive and won't necessarily last the life of your box.

I'd prefer to do a part-change once a year or so to maintain the fluid than use a "lifetime fluid" that maybe breaks down and kills my gearbox. Each to their own though.......

[jagvette]

Yeah, never believed the Lifetime BS

I have purchased Dexron VI, hope it works

Hi

I would only use ZF lifeguard 6, because its never a good idea mixing oils.

would only buy genuine ZF aswell, aftermarket filters allways seem to leak.

Genuine kit comes with Oil, filter, new pins with larger heads and new mecha sleeve, which were prone to leaking on the electric connector.

when you change the Oil, only about 6 litres drains out of the box, about 4 to 5 litres stays in the torque converter.

never known any body have any issues with using zf lifeguard 6, but a lot of people who use a different brand seem to get problems

also, when changing the Oil, ideally you should clear the gearbox adaptations, so the gearbox learns how to shift again and you get smoother shift, sometimes putting fresh, slightly thicker oil in, can make the gear changes quite harsh, also reseting the adaptations can only be done with software like Jaguar ids/sdd and some icarsofts, disconnecting the battery does nothing. Adaptation reset is allways done if the service is done at jaguar.

also if your getting harsh shifts, if the gearbox has never been updated, software update can cure this, last update was 2009, my car was a 2004 and had its original 2004 software, updating mine cured the surging/hunting when it was cold at around 30 to 40 mph.

cheers
