Tranny Oil

[Jackyll]

Is it ok to mix different brands of oil in a transmission? I currently have BG Syncro Shift II in there, but since i'm kind of low on cash right now and it's like $12/quart i was looking for something else to fill up with (i have a slow leak :thumbdown ). I saw Penzoil Synchromesh at Autozone the other day and it's only like $4/quart. Would it be ok if i just pour in some of the penzoil stuff with the syncroshift? Or should i drain the old tranny fluid and replace it with the penzoil stuff?

Also, if i have to drain the oil... I just have to undo the bolt at the bottem of the bellhousing and let it drain right? or do i have to drain something else since i'm AWD?

Thanks for the help

It won't hurt to top it up with Synchromesh. Modern lubes are almost universally compatible.

And fix the leak.
