M56 not engaging in 1st or 2nd

I did a manual transmission swap and installed a quaife differential. Once I put the transmission back into the wagon I was unable to shift into 1st and 2nd gear but am able to get into 3rd, 4th, 5th and reverse. Prior to assembly of the transmission I checked the functioning of both of the two brackets. I've checked online for similar problems and the above thread is the closest description of my problem. I have discovered that the black bell curve shifting bracket works in all three positions but it is the other shifting bracket that is more likely the problem. 

-I've switched the shifting linkage 

-pulled the linkage cable into the car further and pushed the linkage cable into the engine compartment further

-replaced the bushings at the ends of the linkage

-attempted to manually put the transmission into 1st and its is in 3rd

-checked the the ball joint on the shifter inside the car, it is not broken

-had car idling for five minutes after driving in 3rd gear, still not able to go into 1st

-pushed down on shifter attempting to get it into first

-pumped the clutch a couple of times prior to shifting

-bled the slave cylinder to the point there is very little play in the clutch pedal

-looked for obstructions or interference in linkage, it was installed and fed behind the steering column

-the gear box was not damaged and gears, syncros, were physically in good condition

I don't think the linkage is the problem, I think it is something internal in the transmission particularly a problem with the shifting lever on the transmission that is vertical. I am able to go into reverse though.

You're sure the white shifter ball seat is not broken and lifting up? I had a broken one and it would lift and block the shifter from getting into 1st or 2nd. 

But you said you tried to manually put it into first, I'm assuming by adjusting the links on top of the transmission, and were unsuccessful. So that would unfortunately seem to lead to it being an internal issue...
