Hello everyone, my names Ben and I'm from the uk traveling this great country of yours in my lovely el falcon that has some issues.
Basically the auto box is slipping, it was low on oil so we topped it up but it still slips, would this be box or torque converter? We're still driving it and have been for the last thousand k's. Also anyone in Brisbane that would let us use there drive way to change the box if we need to? Have tools and knoledge! Thanks in advance. Ben
