possible th350 to sm465 swap
« on: December 24, 2005, 09:33:00 PM »
My 1978 K-10 has a new TH350 in it, so it will be kept as is, but I have found a 1985 ish K-20 that needs a flexplate.  If I get that truck, I am considering putting a 4 speed and NP205 in it, I have two of those combos, one is already listed for sale, anyway, back to the topic.  I have found the instructions and pictures for the swap, but there were no instructions for making the backup lights work, how do I make these work like they should?  There is a sensor on the side of the sm465 near the shifter, is this what controls the backup lights?  If so, what wires do I remove from the column and put on the tranny and where are they located?  Also, detailed instructions for removing the Auto linkage from the column would be greatly appreciated.

Thanks.
