ok..some new news...i called the subaru dealership and gave them the vin i got the tranny out of and they said the ratio is 4.11. This makes no sense, what else could cause this be?

this is what happens, when i first start the car it shifts fine but after a while it doesn't and smoke starts coming out from the tranny. At first i thought it was just fluid falling on the exhaust, but it's not. As there was nothing dripping. Anyone have any ideas?
