My output flange bolt on my GETRAG 245 was on pretty tight. The 20v cordless dewalt impact gun did nothing but make a bunch of noise. It needed a real air impact gun. So off to a friends house (he had the right tools). I helped him getting his transmission prepped for install. We got the bolt off and new seal and new bolt installed. This inspired me to pull out the Bluntech ultimate 5 speed conversion kit and start installing the kit.
Pretty straight forward. Here are some pics.
