Hey guys, I was wondering if someone could help me out with this. I have an '88 MR2 S/C (4A-GZE) and I am trying to figure out which manual transmission I have? It says in the factory manual that there are two types for that model/engine, those being the C52 and the E51. I was imagining that one is the type with the factory limited-slip and one is not, but even if that is the case, I am not sure which one is which. Just wondering because I wanted to change my transmission fluid and wanted to know how much I need, because its says the C52 takes 2.7 quarts and the E51 takes 4.4 quarts. If anyone could help me out I would appreciate it. Thanks guys!
