Trans Issues With My Mopar 518 Trans

[MR P-BODY]

I have been have shift issues.. both up shifting and down shifting.. it
has all the gears but on the up shifts its WAY to high and doesnt want
to down shift even at zero speed unless I pull it into first/low.. then I put
it back up into drive... I put a gauge on the governor port today and I got
zero pressure when in gear.. as I went up in speed the pressure started
to climb just like it should(1 psi per 1 MPH).. I slowed back to zero speed
and the gauge showed zero.. as I picked up speed the gauge didnt move..
anyone have any idea whats happening with this... thanks for any help..
if I dont get this fixed one final time I sure wont be doing DW

The F-ing piece of crap has to come out AGAIN.. I'm ready to torch the
whole damn thing.. IF I dont torch it.. I'm going to something else.. 5
trans is a bit much... I'm so f-ing pissed

Did you find something while diagnosing the pressure and fluid

Been following and I don't think I have ever seen so many issues with one trans. Good luck!

After thinking about this.. it could have been my fault all along..
I never had the conv cleaned out.. I did the trans last time and
had a shop check it out... if the trash in the conv stuck a bunch
of stuff in there(VB parts and the gov)... I have to think this thing
out... I have the stock 518 that didnt have reverse sitting here..
stock VB.. do I rebuild it and have the conv checked and cleaned
and try again... or I have to start cutting the chassis apart so I can
fit another style of trans in it... I dont know

Don't forget to flush the cooler and lines too.

I did do that in the past but never the conv.. forgetting it or too stupid\
to have it cleaned out

That very well may be your issue. Fingers crossed for you.

Mike when I had Vortec Converter cut mine open it was full shit.... That could be what has been happening

[MR P-BODY]

I have a trans sitting on the bench that was in it the last time.. it
didnt have reverse but had the rest of the gears... I tore it apart
today and seen what the issue was.. I tore both of the nylon rings
on the input shaft... after tearing the whole thing down that was the
only thing wrong... so I'm gonna put this one back together with the
parts needed.. I will have to go through the VB to make sure its
clean.. sending out the conv for a check up and clean.. I want to
get a few things changed on it while its there.... so this is my plan
anyways

[MR P-BODY]

Well the engine/trans is setting on the shop floor once again..
I will give the conv company a call tomorrow.. I tried to contact
the Friday but didnt get them... I want a few things different so
maybe another conv might be in line.. we will talk... the trans is
about ready to go back together.. I've put it together and back
apart about 4 times looking at everything... still need to clean
the valve body and the cooler

[MR P-BODY]

I should have my conv back tomorrow... might get this thing
put back together before I leave for Texas... might have it
back together by Saturday... so I can finish cleaning up
my shop... I also need to take about 30 gals of oil to the
parts store to get rid of it

[MR P-BODY]

Got the conv back this afternoon.. engine and trans are back
together and in the car... headers are in.. the hard work is done
but I've had PLENTY of practice doing this... tomorrow I will see
if I can finish it up but I have a few things to do also

[Nmbr1GMfan]

Fingers crossed.
