Wal-Mart doesn't sell good synthetic transmission fluid for a late model manual. Also, Wal-Mart doesn't have a tech department to help you pick out your oil. Also, the oil must specifically say that it is designed for that transmission. Hence you would be liable, not Wal-Mart.

If you could find fluid for an nv4500 or another high quality late model tranny fluid at Wal-Mart, Post what you find here. Wally world auto fluid is good for the engine and diff's, but not for late model manual trannies. Ever wonder why the oil change rate is over 75K in one of those?
