About a month ago, my radiator "burst" û I assume because of decay, and somehow pierced the tranny cooler at the same time. Somehow fluids that were never meant to interact got together and mass hysteria followed (mine for the most part <img src="/forums/images/graemlins/scared.gif" alt="" /> ), resulting in very thick red coolant, and watered down amsoil tranny fluid (I lost a good amount of tranny fluid in the process). I did have to drive for a few miles - 20 or so - before I was able to get it to the shop. The tranny was slipping badly. My mechanic flushed the coolant system 3x and did a tranny filter and fluid replacement - I believe via the tranny cooler lines. Even now, the coolant is red-tinged, and the tranny fluid looks a little milky. I am in normal temp range, and the tranny operates OK, with the troubling exception of a mild "clunk" when it shifts from 1st to 2nd. My mechanic wanted me to drive it a bit, but has said that he'll do another flush of both fluids.
Has anyone had this happen, and if so, should I be worried about permanent transmission damage? What is causing the 1st to 2nd shift noise, and can this (or should I even bother) trying to have this fixed? Will I ever be able to get clean fluids in each system?
Thanks in advance.
