Default S40 Dissasembly - SHAFTS stuck in case


Im currently dissasembling my S40 transmission.
I splitted the case open, took out the reverse shift fork.
The Interlock guide bolt, and the Shift Arm B attaching bolt.
However i have great trouble taking out the shaft from their sockets. They won't buldge.
I've cleared the INTERLOCK (62th in the attached picture) in up position so it is not in the way of the Three shifts fork during removal.
But the shafts are still stuck.
Can the shafts get stuck if the transmission is in a particular Gear ? Im trying to figure how to know the current selected GEAR.
Thanks

I see your shift fork tower with the reverse pin is still in place. You need to unbolt that you can pull the main and secondary shafts out.

Thanks for the reply
If you are talking about this piece (in the red square) i removed it and the shafts are still stuck.

There is no accessible bolts left in the case that might block the removal of the shafts.
I'm aware that i should try to wiggle them hard as mentioned in some youtube videos and honda tech posts
But in comparaison they seem to take out the shafts quite easily.



If you are however talking about this part there is no bolt retaining the pin
And ive never seen anyone (correct me if im wrong) trying to remove it as they simply take out the shafts out of the case before.

I was talking about the posts with that pin in your second picture.

I can't remember if it's only the reverse cage that has bolts or if there is any more bolts holding the two rods with the shift forks.
If all bolts are out then yeah, you have to wiggle as the bearings the shafts are in as well as the two shift fork rods all are sitting in the case holding it together.

Did the tranny have an Input Shaft Bearing problem ? Sometimes a bad ISB causes the bearing race to stick to the input shaft and it is difficult to remove the gear shafts. You may have to tap it out from the bell-housing side while supporting the gear shafts.
