I'm swapping to a th350 on my 93 lt1 camaro I already got the 9 in th350 shaft and the crossmember with the ta mount as far as i know my flexplate will work also my ds. So my question is how do i get the vss to hook up and also the speedometer. Has anyone done this currently I need help thanks in advance.!

There is no electric VSS on the TH350. You can swap in the tailshaft of a 4L60E or use the ABS signal wire up front to use for speed. ABS would then be rendered useless though. That is the route I took and it works pretty good. You then have to change some parameters in the tune to accommodate the new tire size and you also have the change the gear ratio to a given value (forgot what it was). If you search the forum or google you will definitely find some info on it. Good luck.

I dont have the 4l60 tailshaft because I sold it !! Shouldnt had done that anyways I was thinking about using a speedo gauge out of a gear driven speed like older camaros has any one tryed this

Probably much easier to just go the ABS signal wire route that I did. I have zero braking issues. I never had to lock them up or anything. It was worth it because what I paid for the transmission, rebuild and converter cost easily half of what it would have if I stayed with the 4L60. Bottom line is I love it.

So I did a research like you said from what I understand is this tell me if I'm wrong !
Find the vss connect that was hooked to my transmission cut the connector and strip the ends Next find the abs sensor but which one front or rear ?? The cut that one too and connect both ends together?? as my understanding I.ll have the get the car tunned with 1.175 gear ratio to make the speedo work??

Front. I used the wire going to the plug on the driver side front wheel. Which wire out of the two that you use does not matter IIRC. You sound you like you pretty much have it covered. I cannot remember what I did, it was about two years ago. I THINK I ran a wire straight from the speedo signal wire which was under the dash somewhere (that goes to or comes from the pcm) and connected it to the ABS wire. Sorry for being pretty gauge, it was so long ago. I remember spending lots of time researching online and it all worked out pretty well.
