Sorry for the late reply but I have a really hard time connecting to this site. I think I found a workaround though
It is starting to sound complicated. I'm not afraid of getting out my tools and getting my hands dirty, but do I have to worry about breaking the transmission or causing more damage? In other words, is this a job for a total novice or are we getting into "call a repairman" territory?
I can't see the top of the pump so i really don't know how intricately it's connected to the transmission and how difficult the pump will be to remove and replace.
Does anyone feel it would be worthwhile testing the switch, or are we pretty sure it's the pump? I don't know what is meant by "simply bypass the switch".
I appreciate all the help and advice.
