TH350 9"tailshaft question
TH350 9"tailshaft question i posted this in the tranny section and didnt get a reply yet, so i was hoping someone in the tech section might be able to help. im swapping trannies, the TH350 in place of my 4l60e. I heard that the 9" tailshaft was the way to go so i wouldt have to lengthen my driveshaft. I ordered the GM parts for the speedo and the sensor part number 8655314 is way too big to fit in the hole of the tailshaft where the factory mechanical speedo went. are there different 9" tailshafts made...one with a larger and smaller hole, or what? if so, what make/model 9" tailshaft am i looking for? the tranny rebuilder said that he has only seen 6" tailshafts with that big of a hole. thanks for any help

Re: TH350 9 I believe it is B&M who makes the adapter for the plug you're talking about for the 9" shaft.
I had a 6" shaft on my old motor, and then put in the 700R4 (non computer 4L60) and had a 9" and was forced to shorten the drive shaft.
Now I'm going back to th eTH350 and am needing the same info you do.
