Hey guys, can anyone tell me what the transmission angle should be on a full size Buick? I have been trying to chase down a drive line vibration issue following a transmission mount replace by the following owner. I also feel like the Anchor replacement is pushing the trans farther up into the tunnel than need be for some reason. It looks like the rear end is pointed down 6 degrees stock, but the rear of the trans was almost 10 degrees up. This can't be right. With the double cardan joint in the back, I know you don't set it up like you would a traditional single cardan, which would be 3 up in the back, 3 down in the front, as an example, but I do not know how to setup a double cardan on these cars. All the online walkthroughs are for pickups and jeeps with lifts with the cardan usually in the front with the pinion pointed at the sky. Can someone take a look for me and see how their full size Buick engine is setup by checking the trans angle or just by checking angle on the valve cover? I downloaded an app for my phone to check angle, then just laid my phone down on the cover and at the output shaft and got ten degrees. It is pointed up pretty far into the tunnel. Is the engine supposed to be level, pointed down 3 degrees, up a few degrees to make up for the 6 at the pumpkin or no because of the cardan? ahhh! Someone please help me out. Thanks..
Yes, but your best bet would be to find a chassis manual, I don't have one for that year, otherwise I'd have looked it up for you. But they do discuss driveshaft angles in it.
Alright, now that you mention that, their is a 75 chassis manual over at TeamBuick. I will have a look at that and see what I can come up with. Thanks for the memory jog. If anyone else needs, or wants to take a look. https://www.teambuick.com/reference/library/75_chassis/
