I'm not sure of what you're talking about. The 'manual' valve isn't the same 
as the 'throttle valve'. And I've never heard of a PG shift cable 
stretching. Not saying it can't, but I've not heard of this.

Best (and easiest) way to check the 'manual' valve alignment is to SLOWLY 
move the dash mtd. shift lever between segments (detents), and listen ( 
feel) the tranny shifting. If the transmission shifts (changes mode) at the 
hump in the dash lever's travel, that means the cable and 'manual' valve are 
ok.
