Ka24de Transmission problem need some info

[jeph]

So i took my transmission apart tonight and took a video of what i found out is the problem but i have no clue what im looking at.

 

it seems like the lower gear behind the smaller front bearing is spinning on the shaft a little before catching, my question is, is it splined on the inside and mabey stripped? woodruf key?

 

this video is taken with the transmission in 5th gear notice how much i can spin the input shaft before the output shaft starts to spin

it came out of a stock s14 240sx with 140k miles from a old lady and it had a rod knock.

Nice! is it possible to press the end bearing off and pull that gear off or do i have to find a way to pull that whole stack out?

 

i literally know nothing about transmissions but im good at everything else lol, this is my 4th transmission and tired of buying them so trying to fix it myself this time.

Draw off the counter bearing (bottom) You may have to draw the top input shaft off with top and bottom gears together.

Yeah that's fuckt.

 

New key ways could be cut but the cost...

 

Unlikely you would ever have to take it apart ever again. Nothing to loose if you were to weld it on solidly in place. It's already out and apart.

i was thinking that, i can get a new gear and keys easily but not the shaft, was thinking of throwing new keys and gear then welding her on top of that.

Now me and the mad scientist got to rip apart the block and replace the piston rings you fried.
