I was just wondering which year 5 speeds are interchangeble with a 1978 280z that has an automatic in it and an r180 diffy. I dont want an automatic anymore. Thanks

And also does'nt the manual tranny use the engine oil or does it have a dipstick for putting the oil in or could I be a dip stick for even asking that question.

You should be able to drop a 5 speed from any year Z up to 83. Should be a direct bolt on. Not sure about the driveshaft though. The tranny has a filler and drain plug just like the diff. Drain on the bottom and fill on the passenger side. No dipstick. And it does not share engine oil, it uses 80wt gear oil. :classic:

Hey thanks alot, I was'nt too sure about what years fit.

Depending on where you get it from. Drain the unit first. Inspect the drain plug. There is a magnet attached to the plug that should have all the metal "shavings" attached to it. Wipe it with your finger and then rub the residue between your finger and thumb. It should feel smooth almost like toothpaste. This is normal wear. Anything else like chunks of metal or coarse shavings would indicate an abused tranny.
