I'm guessing the silence on here means that you guys aren't too keen on those aftermarket transmission sealants. Anyway, it's just a stop-gap to put off the expense of a transmission shop - they want $795 plus labor to fix the leak! So I bought a product from Auto Advance that one of the guys it trust recommended - its made by Lucas and i think its called Trans Fix. I'll let you all know how it works out...

I'm wondering if the leak was caused by the car sitting motionless for 4 months - could it have caused a low spot in the front seal?
