I am in the same boat I have a 95 pwm that is going in my 94 hopefully this week.I looked on the internet and found that you do the stake mod for the tcc regulator valve and that will change the 95 back to a on/off tcc instead of a pwm tcc.I cut a spring for the regulator valve to keep it open instead of staking it,then when I got my gasket set for the trans I saw a spring the box and the instructions show to put that in the regulator valve bore,so I could have saved myself some time if I would waited till I got the gasket set.
I think this will work in my 94 so I will let you know when mine goes in or if you try it first let me know.
