Did GM actually produce a quality product????? I wonder who really makes this stuff and where else we can get it. hard to believe a fluid can make that big a diff. Heck, the Integra is due and maybe I'll give it a try.

correct me if I am wrong but the tranny fluid doesn't need to be changed until 30,000 miles anyway.

I think that it's more important to change the differential fluid than it is the transmission. Honda seems to think so also, since they tell you to replace the diff fluid at 15k and the tranny fluid at 30k miles. Don't forget that this isn't your ordinary differential, this has a limited slip in it and that makes a lot of difference in the maintenance of it.
I changed my differential fluid at about 12k and it was pretty black. I put Mobil1 Synthetic in it and with the GM Synchromesh, I have synthetic in both the transmission and the differential. The GM fluid is "partial synthetic" from the label on the bottle.

I have been 4700 miles with GM Synchromesh, and it is still silky smooth. I went from grinding into 2nd gear about 60 times per 1000 miles, to about 1 time per 1000 miles. Those times that I have ground into 2nd, I've either been drunk, or rushing into traffic. I truly feel that it is the "Miracle Juice"!

Just had to add my two cents. I changed my trans fluid this weekend with the Synchromesh and it's a night and day difference. Very impressive. No more 3rd notchy feel, 2nd feels better, no more whiny sound when backing up, it shifts correctly into 6th and the noise level is less overall. Feels like butter. I was most impressed that shifting into 6th doesn't require me to hold the shift knob a little differently anymore. Cool.

Here are my comments from another thread on this subject:

There are at least three good lubes for this transmission that seem to vary primarily in viscosity (keep in mind that none are magic and all will 'feel' better than a lube that has degraded with many miles).
Honda MTL - Overall excellent, and IMO the only one to use with very low ambient temps (it is a bit thinner than the others).
GM Synchromesh - A lube that is raved about by many users (of many makes) and is excellent. Usable in a broad range of temps with a high VI rating. Probably the best overall lube for all but the most extreme temps.
Red Line MT90 - The heaviest of these three and IMO the best when the gearbox is extremely hot. Probably a hair too heavy to be comfortable on a cold start with temps under 20F, but certainly usable. (I would not use regular RL MTL in most temps as it seems to be thinner than all).
IMO the gearbox simply does not perform as well when extremely cold or hot regardless of lube so don't expect magic with any but you can match the lube for the conditions you are most concerned with.
