Well, of course after I had spent like mega bucks getting that "specialized tranny fluid that only GM and Dodge sells" for that NV4500- WTF do I find at autozone? Castrol tranny oil "designed to replace part number 12345690" (or whaatever the speicial fluid GM uses the part number for). So here is a SPECIFIC part number replacement. All I have to say is, crapola! 50 bucks down the drain. /forums/images/graemlins/angryfire.gif /forums/images/graemlins/angryfire.gif You know how much it was? 5 dollars a quart!
