Well, maybe it is heavenly for a while, but I hate to tell ya it is just a fortified mineral engine oil with all the pros and cons.

GMS FM was designed for this tranny:

Note the displacement - 2.2L.

Everything I have found about this product indicates it is a fortified mineral or semi-syn engine oil with EP additives - the FM has friction modifier, but in other applications using the same NV transmissions, FM has to be added. It is all confusing. NV claims it is a "lifetime fill", but if it is an engine oil, one would expect that it would shear down - maybe it is a lifetime fill in the trucks it was designed for, but its questionable shear stability would explain why many people have noted that it deteriorates after about a year of use.

"Synchromesh fluid was developed for use in the NV (New Venture) 3500 five-speed manual transmission used by both Chrysler and General Motors. This is the only product recommended for applications using the NV3500 Transmissions after 1991. Between 1988 and 1991 either Synchromesh or 5W-30 engine oil was acceptable in the NV3500.

Both automakers also use the NV1500 manual transmission, which also requires the Synchromesh fluid. However, the NV1500 transmission requires additional friction modifier to achieve proper performance and protection. General Motors part No.12377916 already has the friction modifier added. On the other hand, Dodge applications using the NV1500 require Chrysler part No.4874464, which does not have the additional friction modifier added. Therefore, an additional 0.2 pint (0.1 liter) of friction modifier must be added to Chrysler part No. 4874464. The friction modifier may be purchased at your local Dodge dealer."

Pennzoil makes the product for GM, and you can find it selling for half the price. Texaco also makes the same spec product.
