engine and drivetrain Need help indentifying 5 spd transmission 79-82 or 83 on?

[AClockworkOrange]

I am trying to identify my extra 5spd.

I am not sure how to tell if it's the older stronger 5spd found in 79 to 82 320i's or the weaker version foung in the 83 320i. Any help would be greatly appreciated!

The stronger ones are the 80-83 with the three part case. 84 - on was a two part case. There were no 5 speeds in 79. G

On the e21 320i, the 80-81-82 were three parts but the 1983 was 2 parts. There was no e21 in 1984, it was the e30 318 with a tranny without the mechanical pick-up for the speedo.

Yes indeed, my brothers, and it purred away real horrorshow — a nice, warm vibraty feeling all through your guttiwuts.

Lee is right, the 2 piece was only for the 83 model year. Its gets confusing though because no E21s were actually made in 83, all 83 models were made in about 4 months at the end of 82.

I hear alot about the 2 piece being weaker than the 3 piece, but has anyone ever broken a 2 piece transmission? I would be incredibly surprised if they have, so far its all been idle speculation in my experience.

Here is some info from the "way-back-machine" around 1987.

Information is from the Metric Mechanic catalog, and most likely was gathered by Jim Blanton who still rebuilds gearboxes/diffs.

I will paraphrase here some....

Getrag 240s have aluminum shift forks (vs brass in the 245s) that would tend to break. Vague and/or difficult shifting and popping out of gear are also symptoms of a bent shifter fork.

Also many '83 240's would get locked in reverse due to manufacturing defects in the selector shaft or the reverse shaft pivot pin moving out of place.
