I have an 87 Olds with a TH200 Trans and I have a chance at getting a 2004R but it needs a rebuild. Does anyone know how much it will cost to rebuild this trans? I'm trying to figure on either buying a new TH350 or going for the 2004R and rebuilding it. Either way it will be a lot of money and work to switch over from a column to a floor shifter and adjust the size of the driveshaft.
