AUTO BOX RESET
A couple of members have suggested that a reset isn't always a good idea. I've searched the site but no-one has reported any issues.
If there's a chance of damaging the box, I think it worthwhile we all know.
Disco-Mikey and Geoff know what they are doing and apparently don't routinely do a reset after a flush.
(thanks for that info Robbie)
Any comments please

depends on how worn the transmission is and what symptoms your having

It is a judgement call as it does carry risk; as such the owner's view has to be considered too.

Hi Geoff.
I guess its difficult to gauge how worn a box is, as symptoms probably sneak up slowly unnoticed.
I assume that a reset puts the box's electronics back to original, before it 'learnt' driving style, but surely that doesn't affect the actual mechanicals of the box.
What symptoms should I be looking for?

It does impact the mechanicals.

i look at milage , feed back from customer and my gut feeling , if the transmission internals are to far worn then resetting may cause problems , but like you say theres no real way to check so its down to instinct and feed back

Hi Geoff, my gut feeling is, its churning at the thought of up a my gearbox by doing something rash

Following on.... When I had the flush done appprox 80k the old fluid was black, new was cherry red IIRC,
I was now considering filter change, (and metal pan conversion) but now after discussion, wonder if filter change needed.

i,d be very suspect of cherry red fluid and would check its spec first

Bit late now I think, was done by 4-tech, who according to their website now don't touch modern vehicles.
I think I'll drop some of the oil to see what colour it is.
Depends when 4Tech did the flush - he did mine about 3 or 4 years ago using genuine oil - but prior to being able to get some did use an equivalent. Not sure how equivalent it was though.Mark.
