I am installing my new engine with a PG but I dont know how to get the speedo working, I've been reading there's a mechanical vss which goes on the tail of tranny and also read you can use a stock t56 speedo. I am using stock PCM, I've been reading a lot of threads but didn't find a powerglide swap thread, search sucks. If anyone has done this I'll really appreciate some help, thanks.
