As we discussed earlier - the 2 small sealing rings that install on the input shaft, that seal the input shaft to the inside of the pump, CAN NOT cause a reverse apply failure, simply because they are the seals for the rear clutch, which is not applied in reverse.

If the 2 rings on the outside of the reaction shaft that seal to the inside of the direct clutch (front) drum fail to seal fail, the front clutch won't apply properly, and you will lose reverse, direct (3rd) and O/D.

I air check my clutch applies both as a rear/front clutch/pump assembly, and again once the pump is in but before I install the V/B.

I was measuring the end play yesterday and I didnt
like what I had.. the spec is .022-.091.. I was at
.085... I wanted to get back to about .045 or so..
I have the thickest thrust washer on the back of
the pump.. I am going to change the triangled shape
one on the front of the intermediate shaft.. with
that one I can tighten it up by .020... this would
put me at about .065 end play.. I can deal with that
I have the hardest time to get all the clutches to
line up when I drop the forward drum in.. I spent
over a hour to get the last disc to line up... it
need to drop down a little farther into the lugs..
what a PITA

I found some issues today... with the help of Scott..
the pump support(stator support was the wrong size for
the input shaft rings... the input shaft is 1.175" and
the support ID is for a 1.240 input shaft... but I had
already planned to go back with all the stock components
from this trans.. so I might not have understood WHY it had
issues.. but measuring it I now think I know why... the input
shaft seal ring didnt come close to sealing.. and when the
sealed blew out I had enough pressure to roll forward but not
enough pressure for reverse.. it had enough pressure to barely
roll in forward... at least this is what I think.. all I did
on this trans was change the pump assm... but didnt know there
was 2 different input shaft sizes... now I am learning that
the early 518(non lock up) which was from 88-91 COULD have
either input shaft.. in 92 they went with the lock up conv
and they changed to the larger input with the hole down the
middle for the conv.... still learning... anyways.. I put it
back together today with the original stock pump.. plus Scott
informed me he thought I had to have the output shaft on to
measure input in play.. he was right.. now I'm on the low end
of the spec.. which will be fine...tomorrow I will sit down
and go through the valve body step by step to clean it.. the
conv goes out Monday

My sources say the larger shaft and 1.245" sealing rings started in '94. shruggy

What's strange is that I saw a non lock up pump with my own eyes today at Mikes with a 1.245" reaction shaft. Not sure how a 94+ pump made it into non lock up form.

Weird...

Scott... I pulled it all back apart so I could do
a final assm on it... I didnt have the low band
bracket in it from the beginning... so back apart and
I ended up pulling the OD back apart being it didnt
want to line up.... total time for the reassmbly of every
thing was 1 hour and 10 minutes including the OD tear down
and back together... I'm becoming a pro on this junk.. now
to figure out issues that cause problems

splines in the OD units often did that when you'd remove them...... always hated that.



Did you find anyplace with a trans dyno?



Did you tear that shifter down and "fix" it so the detents would line up?

I found the one and ONLY dyno in Mich.. but they
wont dyno any trans that they dont build.. plus
their dyno is pretty limited for what it will do..
I will look at the shifter.. but it was working
right... but I'm thinking of buying a new shifter
with a lower shift arm.. I would like a real short
one.. this one is new but its a old unit thats obsolete
now

I pulled the trans apart that was in the car last
time that didnt like to up shift or down shift...
this is the one that I had a shop check over for
me... it had all sorts of rust on the steel parts..
like there was about a 1/2" to 3/4" of water in it..
I know damn a well it wasnt like that when I put it
together... well that was a waste of money and time
