Need Help With 700R4 Valve Body Pressure Switches?
87 El Camino had a 2004R and a 305 with a 4bbl.
Now has a 350 TPI 90-92 speed density 1227730 with a 700R4.
The code for the 700R4 is 3Yp, NO Aux valve body, Type 1 valve body.
My question is do i replace the valve body pressure switches with the ones for a 3YP?
There are 2 pressure switches, according to the factory manual they should be Normally Closed.
From what can tell the 3YP is from a 1983 Monte of Caprice.
trying to get the lock-up to work properly so i can use the TPI to control it.
Any help would be great.
Thanks,
