Who has swapped a TH400, or has a TH400 factory delivered in his G-body? I ask for a specific reason: the backup- and neutral switch are usually on the steering column, linked to the transmission even if you have a floor shifter. I need to find the correct parts to get my TH400 working as a replacement for the old TH200C. The shift linkage from the latter one do not fit anymore as its geometry is different. Any help here is welcome! Even second hand parts for sale are welcome!
