One bottle of Toyota T-IV in a transmission with original fluid

[Rattnalle]

What I noticed with the S40 after resetting the adaptation was less wheel spin

I have some other ideas about improving transmission life...

Are those ideas any fun?

I'm going to stick my oar in here and rock the boat! My 01 XC70 is on 161,000 miles. I have always driven it hard, tow boats and caravans and I have done ALL my own work not just maintenance but major renewals like suspension (control arms, struts). I forget how many times I have done the Gibbon's flush on the gearbox. Each time I use 20 litres of 3309 (Manol from Germany) and use Vida Dice to read transmission temperature and check oil level is spot on. The transmission still shifts like new. I have once Cleared the adaptions and driven them to reset everything. I think fears of messing the box up with a "flush" (not power flush) are simply an 'old wives tale' - I will even stick my neck out and say I think 'drains and fills' are a waste of expensive trans fluid.

I'd say flushing 'more times than you can remeber' instead of the four or so AWs service intervals would recommend in the same distance is way more wasteful

OT
No FAIR! Manny tranny swap on a 01 S40 is a pain in the *$$, not to mention importing a pallet of parts from breakers in the UK
