Hello all,

after contacting few garages , none are willing to work on/ change the CVT gearbox fluid.

One of which said the ECU needs reseting after changing the fluid, and they don't have the equipment to do this !!!

Is this true ,or is it just an excuse for them not to do it?

In other words, can the fluid not just be drained, and then refilled with new Toyota oil?

Thanks.

Hi and welcome to the club

They are lying. You do not need to reset anything. Ive done it myself.

Its also not difficult. Too many mechanics scared to delve in to something different and actually think for themselves instead of using the computer to help them.

Best bet, find a garage that sells import vehicles, and ask them who they use. Guarenteed they know someone.

There is no 'reset' in the official Toyota process.

At most, you'd connect via the obd in order to do a transmission fluid temperature check.

Can you recommend where to buy Toyota CVT fluid TC please?

I am having difficulty finding a uk source for 4L or less

https://toyota-club.net/files/faq/03-03-29_e77-04_eng.htm

(that site is always a very useful source)

indicates that part number is 08886-02105 for 4 litres. Searching on that does seem to suggest a lack of stock in the UK, but:

https://yoshiparts.com/parts/toyota-0888602105

is in Belgium and shipping is £14 so not awful.

You could also try ringing a Toyota dealer with the part number and see if their supply chain has any stock.

The above link says the spec is JWS 3320, and there are some aftermarket fluids to that spec if getting OEM is awkward.
