904 tranny issues

Hey 72swingerwoman, welcome to the site. The 904 doesn't require any vacuum lines, but the mechanical linkage has to be set up properly or you'll eventually damage your tranny. Basically, when your throttle is all the way open, the lever at the tranny should be all the way back. If you do a search on here, I know there are service manual pics and specs of the proper setup for the linkage. Good luck.
