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?

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.......

Yeah, never believed the Lifetime BS

I have purchased Dexron VI, hope it works
