Hi. I need some advice i think i dun f@#ked up...
I was doing a oil pan gasket change with a mate recently and for whatever reeason he disconnected the transmission oil line and lost some fluid. I went out and got some new fluid to top it up however i think i bought the wrong stuff (had no idea and should have checked first). It has been topped up with about a litre of possibly wrong fluid and now it is acting irrationally and getting error codes.
What do i do to fix this? have i completely screwed it?
