Does anyone know if auto transmission coolers have known go get plugged?
Maybe coincidence, but it seems that after I changed my front heater core
that the transmission runs hotter than it did before.  At highway speed it
had run at 200 or less unless stuck in traffic in hot weather after a
highway run.  Now it easily will move up to 220 -230.  This is a 91 wbx with
312,000 miles.  Transmission was rebuilt around 210,000 miles.

Thanks for your thought and comments.
