89 volvo 740 with the aw70 trans and the transmission cooler thats inside the radiator had corroded through in one place inside the radiator...Pulled the pan off the transmission and there was a 1/4 inch of rusty sludge on the bottom of the pan and the screen was completely plugged up with rusty crap too...
I had just done the fluid and screen a month ago so I knew something was up...the only thing I could come up with was trans cooler leaking so I pulled the radiator and opened it up and sure enough where the fittings join the cooler it was all corroded and leaking internally.. Hopefully this trans will recover from this abuse.. So i'll get to flush the engine and the trans for a couple of hours tomorrow...picked up a new radiator from radiator.com for 150
