Fellas Cant find an answer to this, however a very reputable gear box re conditioner made this statement after I purchased an exchange gearbox for my Ford Courier from him. " Your warranty is void if you dont use ATF in the box".
I am certain everyone is well versed in the failure rate of Ford Courier transmissions so I wont share chapter and verse.
Has anyone had experience using ATF in Toyota manual gearboxes and would there be detrimental outcomes if one was to do so. I am aware sulphur content has a relationship to the material used in synchro rings and seals.
Appreciate any advise as I feel gearbox changes are not as smooth as I would like in my 2005 D4D.
