3 to 1 ratio hmmm? What a pain.
I think I am going to wish that I had another TH350C core as the one I have has the intermediate clutch wave washer in about 4 pieces. This (of course) caused the intermediate clutch piston to cock sideways and break, and the wave washer pieces then proceded to gouge the case a tad bit. :whine:

I do have another piston and wave washer but need to decide if I want to use this case......POOH!

Jake..you absolutely rock! I have a book or 2 on the TH350...but laymen's terms and personal tips and tricks are hard to beat. Thanks!

I'm impatiently waiting for the rest of the story...

Jakeshoe:

The direct drum bushing that should be replaced with the wide one is what part number? The TH-350 Rebuild book by Ron Sessions indicates Clevite 01647, or Lempco 6015. The book also lists GM 8622955 which they state is better because it is grooved. Then they even list the Ford part number B5AZ-7B260-A. All this is on Page 240...just wondering which one I should use as my B&M TransKit didn't come with this bushing.

Thanks very much for taking the time to enlighten the rest of us!!!

What is the easiest and effective way to pull out the stubborn low/reverse piston ?

I apply compressed air to its inlet at the rear end of the valve body, it pops a little but not completely and moves no further.

Turn the case upside down and use air. Be sure the parking pawl is out of the way.

Can you show a pic of what passage that needs blocked near the pump to prevent backffed of oil when you delete the lip seal in the drum on the direct clutch pack. I put a TCI full manual valve body in my tranny and it said to delete this lip seal but made no mention of blocking a passage in the case. I been having a very weird screetch/howl noise when I goose it in third and let off quickly just just thinking that maybe the low clutches are apply?
