So the 7/8th is it. I was asked yesterday if I changed them out. I know I had them changed to something and was thinking it was 7/8th but just was not sure. I looked through my notes and I just found something that said dont forget 7/8 chain.
Yes, change out the 7/8ths chain as they stretch... (which in my opinion, is better than the chain just breaking). And when they stretch, they'll take out the input speed sensor reluctor wheel, and then the trans will go into "f-it mode"
BTW, for anyone that happens to and you're out driving, unplug the trans electrical and it'll go into limp mode where it's only in 3rd gear. That's what Trannyman told me to do when my car was acting a fool.
