Th350 hydraulic schematics I would think these would be readily available, I used to have a haynes book with them in it. I wanted to look into turning the LOW/REV clutch on in 1st gear D position for a rock crawler trans. But damned if I can find them online anywhere, I did find the old haynes book online ebay but people want 100 dollars for it. Figure someone here might have these ? Want diagrams showing flow for m1 m2 d 1-2-3.
Have a couple guys who have come to me they do rock crawling and say wherever then have them built the work fine but they tend to shatter the low roller.
I have done this mod with the 4L60E and 700R4 for plow trucks a number of times. But never looked into it with a 350 and honestly probably only done a handful in the last 25 years (don't get much call for them anymore). I can probably figure it out flowing channels and such but the schematics would make it much easier.
Thanks if anyone can help with this.

All good I will figure it out, should not be too hard just block a place and redirect oil to the 1-2 valve. The diagrams would have just made it quicker and simpler. Cant believe an old haynes trans book is over 100 on EBAY now lol and out of publication for the TH350. Maybe I should have kept all those old books i had from the 80s lol

I feel your pain. As soon as you think something is obsolete to your needs and get rid of it you will need it. I got rid of a bunch of 350, 700R4, T440, 125 and a few 200 metric cores because I haven't rebuilt any of these in years. It wasn't long afterwards someone come in with an old tired, worn out 350. Oh well that's the way it goes, don't have the storge to keep that stuff forever.

I have the original GM schematics
Also have th350c stuff
What you want to do is not too difficult
I offer a valve body like this
also have transbrake valve bodies that are reverse pattern that have the low/rev clutch on in low to support the roller clutch
