Torque converter getting hot

Hi well I installed a torque converter in a D9 19A and it got hot very quickly so took the torque converter cooler out and looks like this hopefully is the problem. I’m assuming it probably hasn’t been cleaned since 1957 lol and the oil cooler as well! I will flush the cooling system and clean pressure test the coolers before installing any other things I should do? Thank you Clayton

Looks nasty Clayton! Should be an easy fix though - fingers crossed!

yeah well theres your problem i would soak it in a cleaning solution rather than mechanical means. see if your local radiator service will hot tank it for you. or make your own hot tank.

Hi, clayton.

If my memory serves me rightly, those early D9s also had an air cleaner for an air supply to the torque converter for additional coolnig. If there is one, have you checked that to see if it is restricted?

This photo shows the second air cleaner pre-cleaner:

Hope it helps. Also mighta bin for the master clutch.

Just my 0.02.

Actually for the brakes.

Hi Deas Plant Bluox is correct about the air cleaner it’s for the brake system. Bluox do you have any idea what the temperature difference should be on the torque converter cooler?

Just off the top of my head maybe 15 degrees.

Do you have a serviceman book?
