Default Is a working PWM solenoid needed when eliminating PWM function

Hi guys. I'm currently rebuilding my 4L60e myself. What I thought would be $200 in parts is about $1400 in parts so far. I am installing the Sonnax Performance pack (HP-4L60E-01). I am currently working on the valve body. I took it apart and noticed that the PWM solenoid is damaged at the connector. The connector is cracked and attempting to separate from the solenoid body. I ordered what should have been a replacement solenoid, but instead of a PWM solenoid, I accidentally ordered a 3-2 solenoid. I can order a PWM solenoid, but that means waiting a few days each time I place an order (I'm tired of the delays).

My question is as follows: In the sonnanx valve body section, it mentions that this is the only kit that gets rid of the PWM function. Since the kit is designed to eliminate PWM function mechanically, will I be wasting my time by ordering a working PWM solenoid? Can I simply break off the connector portion and use my broken PWM solenoid as a dummy plug, or must I have a PWM solenoid plugged in (for electrical purposes)?

Oh, and I have HP tuners for any mods to be done on the programming side.

The computer will still recognize the solenoid. If it is not working, it will send a code as far as I know. The computer does not know that you made an internal change.

Thanks for the response.

Question 1: Can I get away with using the cracked solenoid? I mean if hardware changes are made and PWM function is eliminated, is there stress on the solenoid from it being activated, that may cause it to eventually break off?

Question 2: Since I have this second 3-2 solenoid, and it is identical, can it be used in place of the PWM solenoid? I figure that the computer will sense something plugged in. Should that be enough?

It may sound like I'm being cheap, but $1400 later, little things like these are really aggravating when I have to wait days to get each item.

The only year that uses the same solenoid for both is the 1995. There is no real pressure on the switch that should cause it to break when activated. You can try it and see what happens.
