4+3 Doug Nash Service in SouthEastern Michigan

[C4-Newbie]

Hi All ... new to me 85 C4 with doug Nash 4+3 Manual and looking to have it serviced. Understand lots of issues with OD unit so want to get the fluid and filter changed but having hard time finding service center familar with this unit. Any suggestions. Thanks

Not hard just get the filter and gasket and drop the small pan, replace and put fluid in via the plug on the side. I have had 85 for over 10 years with no issues with the OD unit except having to replace the switch that used to be in the gear shift with a toggle switch now attached on the left side by the radio. Even the Haynes manual shows what to do with pictures
