| + | ===Muncie 4-speed=== | ||
| + | A GL4 spec non synthetic gear oil is recommended. | ||
| + | |||
| + | The problem with using synthetic transmission lubricants is the 'threads' on the inside of the bronze synchro ring are there to 'cut through' the oil film, and the trans uses the lube as a sort of a friction brake. Really slippery lubricants can allow the synchro ring to skate across the film and the gearbox won't 'slow down' quickly enough, causing slower, noisier gear changes. | ||
| + | |||
| + | If you must use a synthetic, use Royal Purple MAX GEAR (NOT "Synchromesh") in the 75w90 range (140w is not necessary). For the Muncie, 1 quart is all you need. (There was a lot of casting core problems and the fill and drain plug locations migrated during production, which makes the 'fill until it leaks out of the fill hole out' problematic.) | ||
