[RHYSF00]

Hi all. So just want to check this before I do it. I am gonna need to change my transmission oil as there is zero evidence it was done in it live time and I think some has burnt off. I am unsure if I need new washers.if I do what size and sort of washers is needed. Car is in my profile

Yeah you should fit new aluminium washers, I bought them from Toyota, can’t remember the price but it was not expensive.

Ok. Is it worth replacing if so do you know the size as I'm doing the replacement Friday as I am going away to Dorset for the day on 17th.

They are not standard washers, Toyota will probably have them in stock.

Ok when I last went to Toyota dealer they didn't seem confident in their answer saying it reusable.

My manual says replace them, if you don’t they could leak, is it worth the risk for a pound or so, if Toyota have to order it, usually it only takes a few days.

It’s difficult for me to remember, but I may have damaged one undoing the nut.
