1975 Grand Safari Wagon transmission
 

Would a 455 powered Grand Safari wagon come with a TH375 or a TH400 transmission? Mine has a 9” tail shaft housing, but it doesn’t say on it which it is.
The code on the tag is PC, but I haven’t been able to find any info on that.
I’m about to have someone rebuild a core for me, but he says that I need to know which it is, as the splines are different, and I would possibly have to change driveshaft yokes. Thank you.

It should be a TH400.

PC is for a TH400 with a 455.

Thanks John!
