I thought the wrong spring might have had something to do with some trans issues I was having, but turned out to be a band that was adjusted whaaaay to tight.
So I agree the directions (replace stock spring) and spring with different dimensions are probably what was intended by superior.
I put the bias spring from the superior HP kit back in since I didn't think it had anything to do with my original trans issues. But I think things look good so far, seems to shift through all gears and pressures are:
P - 90/220
R - 150/250
D4 - 90/220
D3- 90/220
D2 - 190/190
D1 -...
I think I finally got somewhere, I removed the servo pin and pistons to see if my D1 Full TV loading would disappear and it did. Then I started looking more closely at the pin adjustment and it was way way too tight, band was essentially applied from the cover pressure. Back in march when I...
I'm not sure of the rev boost size (it's stock monte SS), but I will measure it next time it's out, I'm sure it will happen soon.
Will the .296 Rev Valve give boost to about the 200 psi mark so things are essentially equal between WOT D3,D4 and manual D1, D2, any preffered source/brand...
When you say it just coasts, do you mean, that there's no engine braking (car slows with engine revs), what about engine braking in first and second.
Can you get it into 3rd by downshifting from 4th into 3rd?
Sounds like it is probably a high milage car, so if your not considering a...
If you temporarily disconnect the TCC cable connector altogether you could see if your questionable 4th shift in D3 range is lockup since it should disappear with no power to the solenoid.
I had a tough time removing one too. In the end I was able to start rotating it with a pair of vise-grips, which worked it loose and let more pentrant in, but it did some damage to the speedo cable threads. If I had the end of an old speedo cable to thread on first I probably wouldn't have...
(If someone had a link to the 200-4r OIL circuit that would make this more understandable to those less familiar)
In trying to determine what the pressures I was seeing meant, I wanted to understant how the Pressure Regulator (PR) worked and was controlled, but I found mostly bits and pieces...
The "Line Bias" Spring included with the 200-4r-HP kit seems a lot different that the stock...
Original Spring: .275" OD, 1.4" Long
Superior 200-4r HP Kit (green spring): 0.231" OD, 1.1" Long (much stiffer)
Does this sound right and should it replace the existing (as per instructions) or...
Thanks for you comments bison, it made me did deeper into why the pressure numbers were like they were in my manual. Hopefully, I'm coming to some correct conclusions though...
After some thought about what is shown in the GM principles book, I don't believe the main boost valve will have...
I agree, that the pressure shouldn't drop in D1 with FULL TV, I need to make sure this isn't due to the drop in RPM when the engine loads down because of the tranny problem. I would also think D2 should be 190, 190 based on the others (again maybe rpms were too low, will test again).
What...
After removing the VB and checking every valve, sleeve and spring, nothing looked bound or improperly located. I was suspicious of the "Line Bias Valve" so I went back with the original one and also removed the TV exhaust check ball. After it was back together, the line pressure started...
I just compared the Line Bias Spring that was installed from the superior 200-4r HP kit and it seems very different than the original one:
Original Spring: .275" OD, 1.4" Long
Superior 200-4r HP Kit (green spring): 0.231" OD, 1.1" Long (much stiffer)
I read another post refering to an...
I decided to remove the rev boost valve and boost valve, leaving the valve sleeves in place. The result is that the line pressure dropped to about 60-70 psi cold, so I think this means the pump and regulator are working and that the problem is that either the boost or rev boost signal at the...
