help needed with 904

TrailBeast said
The ball left out per the kits is only for the most firm 1-2 shift.
If the ball was left out for the reverse circuit it might have had a little bit of reverse only when the fluid was cold, and it would go away completely with hot fluid.

Thanks TrailBeast, I couldn't remember which ball.
Looking at the flow diagrams I see that besides the big 3/8 relief ball,there are actually 5 small 5/16 balls, AND 1 of 11/32;and all but the # 6 are too prevent the dumping of pressure at the manual valve when manually shifting. Only #6 might be expendable. Unfortunately the ball locations in the VB are not identified with numbers, so I can't help with finding which one is which.

I'm converting from my 4 Speed to an automatic.
Building a small motor for my wife to drag race the car so it will be a race application

budget 318/360 my forward thinking brain (what little I have) is thinking about how I'm going to approach this unknown transmission?
AJ it's the same 410 dana 60 spool 35 spline thats already in the duster. 90% track. 29in slicks (I think) and 28in street (I think). Again right now I'm gathering up ideas for an approach.... thank you

Well one idea that came to me, is that to use those 4.10s that teener is gonna want some snort. I see 5500 wanting to hit 106. and that will require a p/w of 10.4. With a 3200pound raceweight that equates to 3200/10.4=308hp. So the teener will need to be making that at around 5100. Other numbers are of course do-able. She will sure squirt out of the gate tho if that is a low-first tranny.Even with 29s. I ran a stockish teener one winter with 4.30s, 28snows,a 10 inch 2800TC called a "DirtJerker", and the 2.74 low; WOW is all, ....I.....................can.........................................say
