the gibbons method would empty about 90% of the fluld mabe even more as your using the atf pump in the auto box to pump it out

yes flushing it through would but ive allways favoured changing what drains out then redoing a few miles later so as not to over clean box in one go but would depend on whether regulary serviced ,can be a bit of a shock for poorly serviced ones

am going for the full flush mate shes on 103000 miles and i doubt the atf has ever been changed
The Carlube fluid seems to be compatible with 7045E which is the higher specked version of Texaco N402 now known as Texamatic 7045E. It's used in some BMW autos, BMW call it BMW 7045E!! This is listed in the specs
Being a synthetic fluid it's spec far exceeds the N402 mineral based fluid!!

yes mate 45kmh is 30 mph this would be the change from 3rd to 4th ?
If not just a roughish but very hard change check your 2/4 duty solenoid as
you can damage rev clutch plates and cause fracture in basket piston which ends up in slip in 4 and 5 HTSH
You'd need at least 12L if you were going to do the complete flush. A gallon will only be enough to change around 25% at best depending on how much you can drain from the sump in one go. Why not go for the complete flush? The Carlube stuff is quite reasonably priced too so why not go for it

because if oil hasnt been regulary serviced the high detergent qualities can cause issues with valve block etcYou'd need at least 12L if you were going to do the complete flush.

no if there is high levels somethings breaking up ,detergents do that but can cause issues of their own ,its not an uncommon issue with auto boxes ,valve block is a precsion fit piece of kit
After lots of ATF changes for not just myself but friends and family seeing the condition of the stuff that comes out I would imagine it can't be doing any good to the internals of the gearbox.
Old ATF contains contaminants in suspension which reduces it's ability to maintain lubricity and will start to break down at lower temps the older and more contaminated it is.
Every car that I've changed the ATF in has always had a massive improvement in the feel of the changes.

oil changes are good and vital for long term life of box ,but still with complete flush its worth thinking about whether it might effect operation,an opinion based on rebuilding auto boxes not google

That may be true, but they won't include our jatco on their website. They also don't show atf for my v6 when entering his reg plate, or another v6's reg plate. I don't see why not. Any moron could do it. They would sell a lot more oil.The Carlube fluid seems to be compatible with 7045E which is the higher specked version of Texaco N402 now known as Texamatic 7045E.

It's going to be miles better than what came out!!
Yes, drove it in manual today and was from 3 to 4. Once oil luke warm it all went smoother though.

mines is the same mate but once warm it changes smooth. i think they are all a bit like this when cold. my concern is the lock up in 4th and 5th so fluid change is a good starting point in any case
