Neutral Safety Switch on TH-350

Please correct me if I am wrong on this. It is my understanding that a Neutral Safety Switch is IN some TH-350 transmissions. If so, how is this switch wired? It only has one terminal. I have a floor shifter (Hurst Pro-Matic) that does not have an incorporated NSS. I would rather not buy a new shifter if a don't have to. Thanks.

you are incorrect. No switch in the t-350

The neutral switch was usually on the column if a column shifter.... on the floor shifter IF a OEM shifter is used

If its a 69 Nova its under the column..........Even if its a floor shift, they had a linkage up to turn the piece on the column too..........All part of the key in the column incorporated that year. That's how my Chevelle was anyways.

To the best of my knowledge that is a lock up converter terminal,TH350 never came with an internal neutral safety switch.

Some early 70's Chevy/GMC vans with the Turbo 350 have the neutral start switch mounted ON the transmission. The case has two extended prongs cast into the left side of the case just above the shift lever.



Most column shifted GM's have the neutral start/back up light switch on the column. The column above is a GM van ... look and you can see the switch.




LOKAR makes a somewhat universal fit neutral start switch that should be fairly easy to adapt to your Turbo 350. It mounts to the transmission pan and has levers that work in cojunction with the shift lever coming out of the transmission.
