Hi,
Im trying to top up the ATF fluid but cant work out what size sqaure bolt it is, it looks to be somewhere in between 3/8" and 1/2", does anyone know what it is ?
There is very limited access to it but i can get a 3/8" rachet through the coolant pipes, just dont know what i need to open it.
I have photos but it wont let me reference photobucket links

Re: ATF Top up bolt size
You top it up on the power steering reservoir not the rack!!!!!
