I just finished changing my trans fluid and filter and replacing the k-1 spring.
Things went very unusual. By unusual I mean that no stripped or snapped bolts or the usual dramas that turn a 3 hour job into a mission.
Every thing buttoned up nicely and it comes time to top the fluid up. I proceed to open the engine oil cap and start pouring in transmission fluid in.
I put somewhere around 10oz in the engine before my brain turned back on and snapped out of the euphoria of a job well done almost being complete and I smacked the funnel out of there.
So. Im probably not the first person to do somethin so stuupid so don't ridicule me.
Ive been 2700 mi since last oil change. Can I let this ride? 200mi of driving planned tomorrow morn. Do I need to set the alarm real early and change the engine oil or will I be ok?
