Rich you have to have a spring on the small wt. or it probably won't shift> with the spring off of the big wt. it brings the light throttle 1-2 & some what 2-3 from what I've found.
I have the same symptom, "shifts early after 20 mins of driving." How did you fix this?...On my trans, it would shift out early when the car warmed up because of the stuck TCC solenoid...

Yeah sure.Have you tried re torquing the VB?
Spring is stiffer than original.all quality pieces. did you get a spring to go in there with the boost valves?
No! It doesn't downshift right.AFTER YOU SHIFT INTO SECOND ( LIGHT THROTTLE ) AND FLOOR THE THROTTLE,DOES IT DOWNSHIFT INTO FIRST?
Besides the weights,and governor spring,the spring pressure in the TV limit valve will effect your shift points especially at WOT. More spring pressure,higher WOT shift points and higher MPH downshifts. You must have a way to measure spring pressure and you need to measure the pressure at the installed spring height. A kitchen scale works well for this. A difference of 2 ounces of pressure can make a big difference. You can also install a lighter spring in the governor but you must know the springs pressure or else you're just guessing. I suggest you start with a change of the TV limit spring pressure of 2 ounces higher pressure and see what you get from that.Spring is stiffer than original.

It's possible the TV limit could be stuck too.Besides the weights,and governor spring,the spring pressure in the TV limit valve will effect your shift points especially at WOT.

To see how it will effect your shift points to get from where you are now to where you want to be or you could purchase a valve body/governor combo.Tv limit valve is not stuck. I wonder why should I change the spring on tv limit valve, when it doesn't say me to do so in shiftkit
Yes. No.When some one pushes the accelerator pedal to the floor inside the car,do the throttle blades of your carb move to their full open position?
If so,when the throttle is wide open,can you pull any more TV cable out of the trans? You shouldn't be able to as the throttle valve should be at the limit of it's travel.
I don't know the color but I do have the dimensions. Wire diameter: 0.033" Spring O.D.: 0.371" Free Length: 1.765" Number of coils: 14Yes. No.
Changed the tv valve by Sonnax. Didn't really effect that much.
Can anyone tell me what color is the tv limit valve spring? I mean the stock spring.
It was that kind of spring! So that is correct.I don't know the color but I do have the dimensions. Wire diameter: 0.033" Spring O.D.: 0.371" Free Length: 1.765" Number of coils: 14
