Fluids check/change

[suobs]

Hi, I wanted to do a complete lubes change on my 1994 4x4 King Cab D-21 pickup, manual transmission, 4cyl engine.

Sorry if this is a stupid question, but am I correct that on a 4x4 manual trans I have the following to check and replace lube in:

• Front differential (drive axle)
  Rear differential (drive axle)
  Transfer case
  Manual transmission

Correct? If I've got that much right, what/where is the transfer case? I have two shop manuals and both seem to assume I know what it looks like and where it is . . . and whether I have one on my truck

The transfer case is attached to the rear of the transmission. Both front and rear driveshafts attach to the transfer case.

Don't forget engine oil.

Thanks! I'm an old hand at engine oil! . . . nothing else though . . .

I suppose this would be an ok thread to throw this in...
My trans in my 95 4x4 xe with a KA is numbered Fs5W71C. As I recall there were a few of the transmission that did not require the over filling. Does this serial number fall under the overfill club? Maybe I am imagining reading there were transmissions that were exempt from the over filling.

Yeah, you don't need to overfill that model. Only the 1986.5 - 1995 4WD FS5R30A is affected.
