Does the transmission fluid on the 300sd flow from the transmission to the radiator on the driver side and return from the radiator to the transmission on the passenger side or vice versa?

"Danger takes many forms"

thanks for the reply. though it's not clear whether your answer "yes" means yes it flows from tranny to radiator on the driver side OR "yes" it flows from radiator to tranny on the drivers side? I would be helpful if you could clarify.

'83... it was a very good year.
