| − | The E30 was available as both a Manual and an Automatic. In total, seven different gearboxes were fitted to the E30; four manuals, all produced by Getrag, and three automatics by ZF.

| − | The gearbox, prop-shaft and [[Differential]] make up the [[Transmission]], and gearbox ratios are also dependent on the ratio of your diff. For example, a high ratio diff (4.27) combined with a high-ratio first gear (3.72) will make first gear useless. In contrast, a low-ratio diff (3.25) with a low-ratio gearbox (2.48 in first)

| − | When upgrading the [[Engines|engine]] of your E30, you should also consider what effect this will have on the gearbox. When changing your [[M20B20]] to [[M20B25]], the gearbox is compatible, with the Getrag 240 gearbox of the former engine having similar ratios to the Getrag 260 Sports gearbox available for the latter. However, the 240 isn't as strong a unit, and may break prematurely.
