4l80e shaft for non-NSS
4l80e shaft for non-NSS I'm planning to delete my neutral safety switch on my 5.3/4l80e swapped 87 Monte Carlo. Once the NSS is deleted I will have a lot of extra shifter shaft sticking out of the case that is no longer needed. I've read about changing the shaft to an earlier, shorter, version from the pre-1997 4l80s. From my research I have found that the shorter shaft is Sonnax 38511-03K.
My question is can this shaft be changed without taking apart the transmission?
I have seen many posts of people asking the question because of a pin that holds the shaft in but no answers as to if they ever did the change and how they did it. I need to know if the shaft can be changed because if it can't I'll need to buy a shifter cable support bracket that is designed for the longer shift shaft.
Thanks,

As long as the trans is not in the car. I haven`t tried it on a 80e in a g-body, but I can tell you that changing the shaft on a 60e in a g-body is a massive pain. The shaft on the 60e slides out of the case and hits the floorpan. I was able to do it with some prying on the floorpan but it might get ugly with the larger trans. Hopefully the 80e hangs low enough for it to clear the pan.

Thanks for the warnings, fellas. No worries on the space to work, my engine and trans are being pulled in a few weeks for upgrades so the trans will be out and on a stand when changing the shaft.
