Post B6T transmission VS KLDE transmission VS MTX75 diff
I was bored tonight and decided to tear down a couple of spare transmissions I have...

I picked up a 94 2.5L probe transmission for $50... I didn't know what shape it was in but I had hoped to rebuild it... Unfortunately the whole thing is going to the trash can...

Probe transmission..
Image

Upper case half, under 5th gear... :bash: Counter shaft chewed into the case half rendering it garbage..
Image

Lower case half.... :bash: Toast!
Image

Counter shaft bearing blew up... :eyes:
Image

Now on to the fun! B6T and KLDE guts on the bench...
Image

A pile of case halves...
Image

I'll start at the top... The back covers... KLDE on the top, B6T on the bottom... notice how much flatter the B6T is...
Image

Inside of the B6T back cover...
Image
Inside of the KLDE back cover..
Image
The KLDE cover is changed to help pick up more oil and feed it to the counter shaft... The back covers are interchangeable...

Rear case halves are almost identical... There are a couple noticeable differences... But it looks like they could be interchangeable... The KLDE one has slightly different casting to accommodate a different rear mount set up..(didn't get pics) If you were to use the KLDE rear half on a B6T/BP car it looks like it would work, but you couldn't go the other way...The KLDE rear case half has extra ribbing around the diff area.. I am going to assume this is for more strength..

Also different is the oil guide that feeds the rear cover(5th gear) with oil... The KLDE one is larger and more open.. more able to catch and transfer more oil... It also extends into the front case half area...
Image

The B6T one... its metal and shaped completely different.. smaller and doesn't past the rear case half area..

On to the front case halves... They are totally different as expected... KLDE uses a hydrolic clutch set up.. where as the B6T is cable... The bell housing bolt pattern is totally different and the starter locations are different... Interesting to see though... KLDE has improved pick up areas for feeding oil to both shafts...

B6T...
Image

Also changed is the shift gates and reverse lock out... Not sure why.. it looks like both could be interchanged...

Shift forks are totally different...
1-2 select fork for a B6T is aluminum... KLDE is cast and a completely different shape... Not to sure about interchangeability but I'll play with that when I get to rebuilding a transmission for my car..
Image

3-4 select forks are completely different as well... The one I am holding is the KLDE one.. it was broken when the trans blew up...
Image

Diffs as we know are swappable... The KLDE ring gear is slightly thicker...
Image

Now for fun... I was looking into the possibility of using a focus (MTX75 diff)... So here is all 3 lined up... the MTX75 diff is taller, the ring gear is positioned differently... all in all wont work...
Image


Shafts are almost identical when you look at them...
KLDE on the right...
Image
Image


Now for the good stuff... gear ratios... my eyes are pretty sore from counting teeth...

Probe KLDE is the same as all the info I have found..
1st 3.31
2nd 1.83
3rd 1.31
4th 1.03
5th 0.78
Final Drive 4.39

B6T
1st 3.31
2nd 1.83
3rd 1.23
4th 0.97
5th 0.795
Final Drive 3.85
