Glad you found it without any more damage, I was lucky with mine too, mine blew out in August, I was climbing a long steep hill, rpms jumped from 1500 to 3400 as it down shifted, temperature gauge was nearly pinned as I crested the hill. Plastic parts should not be in there, I don't know what they were thinking, that pump was only a year old, replaced it with a lifetime over the counter warrantee one, but that doesn't help with labour.
