Jatco Gearbox Fluid. What Are The Alternatives

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

Carlube (or tetrosyl on their emails) confirmed to me their product is suitable for our Jatco by email. However, when asked to add the Freelander Jatco to their web site listing, they don't. Why not? Surely it would increase sales. There's a number of cars missing. Paragraph 1 in the disclaimer of their datasheet posted above is quite good I think. I think they should come out and admit they likes Freelanders (if they really does).

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!!
 
As the last couple of weeks I start getting rough gearchanges especially around 40 - 45 kmh (is around 30 miles I guess) I think I better keep a close look on this thread.

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

I've ordered a gallon of ATF-U so I'll see how it goes?

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 etc
 
So the high level of contaminants in old oil is better for the valve block? :)

Of course everyone one has opinions, mine is that the detergents help to clear build up of deposits in areas where they shouldn't be.

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
 
I thought I'd refill the trany for the minute. I need to check the replacement engine is ok before I waste £60 on fluid which might end up being drained anyway!!
 
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. :confused:

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
