well thats going to be hard to do dont have a camra... but ill see if i can surf the web and find one and stick on here.. but ya, its a plastic valve with a metal rod going through it.. weird ive never seen one.. do you know what type shift kits are used in these? what im doing is building a transmission for a spare for my company trucks and i bought this core.. it had some cool shit in it,, the beast sun-shell, this little valve,, i have not been in the v/b yet to see if it has been molested or not.. but i need a stock trans here and i think im in trouble..

Are you sure that the main valve is plastic? I have seen superior kits use something very similar to what you are talking about but the main valve is a composite metal. If the trans had a pink 1-2 accumulator spring and a blue pr spring I would say it is a superior kit. Vince

those kits are for re-routing the fluid path into the converter for a non lock-up converter application.

IF you install a lockup converter into a trans with those non lockup kits installed... Soon as the engine is started , the converter clutch is applied.... it is all about oil flow paths

No the lock up still works. If I remember correctly it helps reduce or eliminate the pwm function of the lockup clutch. Basically removes the pulsing of the oil and makes into an on/off system.
