This is for my 99' S10 with the NV1500 manual transmission. While I'm not really trying to cheap out on my truck, GM's 88900399 Synchromesh Friction Modified fluid is kinda spendy for a worn out 5 speed, especially since you need 3 quarts. Dealer wants almost $30 a quart and online it seems to be almost $20. Is there a compatible alternative that doesn't cost so darn much?
