I believe this is my shift pattern
do you think this transmission will be sufficient?
After I have motor rebuilt NTC 350 SC I’m going to have a shop go through it too
Also what rear end gear ratio should I run?Attached Files:

The original shifter pic you posted may not work on some because the top position is not a splitter control so the air plumbing is different.
The RTO 9513 was fine behind the NTC 350. 8th OD “13th” gear is super noisy at cruise speeds. But that means it’s healthy. Lol.
Like @wore out was explaining you only preselect the range up or down but you post select from od to dir. you preselect a down shift from dir gear to a lower hole od.
Upshift Pattern low, I,2,3,4. Then preselect
5, split to 5 od. , leave in od shift to 6 and then select to dir for 6. Then split back up to 6od. Leave in od and shift to 7 then select to dir for 7 then split back to 7od. Same thru 8th.
downshift pattern. From 8 od select dir for 8dir. For 7od preselect od and shift to 7od and then select dir for 7. And so on. If you don’t do this it will constantly neutralize even with shifter in a hole.Binderdavemays1 and wore out Thank this. -
