Hey thanks! Yeah, it sits like a factory install. I can't take all the credit. I had the designs, ideas, and options. The shop did about 75% of the labor, the rest was helping and fixing what they screwed up. Sad huh? Anyway, 3-4 accum.....I'll get the Borg-Warner standard replacement OD clutches. Will those address the lube issue? I hit the 3-4 shift at about 105-110 MPH. I was just wondering if I'm in in 4th and TCC locked and nail it, if I can get it to downshift faster.

I've seen the TransGo kits. I thought they just had stock replacement springs and what looks like shims as well. What exactly is in them and should I get one? I have the valve body off and channel plate too. My HP will change later down the road. I have full control over line pressure. How much psi vs. tps at my disposal. If I end up making things to firm, I can take line psi down. I guess the main question is: will I get the same effect if I were to drill holes, or increase line psi, or shim the accums, or add stiffer springs to the sccums, or any number of those combinations? I do know each one individually to some point will give a firmer shift, but can I have a faster shift without a firmer shift?

I could go further in the tranny, but money won't let me. Looking at the 1-2 and 2-3 accums while installed in the tranny, the larger diameter springs are on top, and smaller diameter springs are on bottom. Why the two sets of springs? Won't they offset each other for the most part? one set of springs is for upshift, and the other set is for downshift correct? Which is which and why? If I were to just shim the downshift side, wouldn't that speed up the downshift?

Good info about the feeds. That's what I was thinking about doing. I just didn't know by how much. Why not drill the exhaust too? From what I was told, the shimming forces fluid at higher volume and psi to the clutches, making the upshift faster and firmer. Allowing the fluid back out of the clutches faster makes for a faster downshift. Correct?

When I make these mods, I will go conservatively. I have shims, springs, drilling, and line pressure to play with. I figure if I do a little here and there, I can fine tune with line psi.

Thanks Trannyman. Your info is what I'm looking for. I need to shrink my pix big time so I can show you some other stuff as well.
