Chevron Meropa is an ISO-1500 grade which is equivalent to SAE-250 grade lubricant. This stuff has extreme pressure additives in it so it wouldn't be kind to any phosphor bronze bushings such as the reverse idler. Most old transmissions use the lubes with no EP additives like GL1. Restoration Supply touts that it is good with yellow metals but I wonder where that information came from. Chevron's info even states it has the heavy smell of EP additives.

There are other ISO 1500 lubricant available that have no additives.
