5 speed manual transmission

SOURCE: Swap 5 speed neon trans to 5 speed talon

Check the bolt pattern on both transmissions. they should be a match but may need a washer to make up for the depth of the neon trans

SOURCE: leaking oil at spline shaft slip yoke at rear of transmission

there is a long bush type bearing in this tunnel just at the end were the seal fits in it can were out and let the prop shaft flap about, this in turn rips the seal to bits,,,also the yoke has a polished part on the end that go's over the spline into the end of the gear box tunnel the seal can were a groov into this part, and no amount of new seals will stop it leaking them as the new seal runs in this worn out groov, again ripping it to bits,,,test the long bush type bearing by holding the prop shaft yoke and pushing it up and to the side, if it moves about replace the bush in the end of the tunnel as well,, its a push in fit! with a big hammer!!
if the yoke has a groov in it you need a new prop as all prop shafts are balanced so you can just fit a new yoke it could throw the car up in the air when your driving it down the free way,,,,by shaking it apart
i hope this is of help to you
