4l60-E transmission circuit ?

[mdmilburn]

my 97 blazer has codes P0740 tcc solenoid malfunction ,P0753 1-2 shift sol. A malfunction, P0758 2-3 shift sol. B malfunction............now is it likely that all three solenoids can go out at the same time? ,and do you have to remove the valve body to get to any of these .right now the truck does not always set these codes but youll shure feel it when it does

had the tcc solenoid replaced yesterday (AAMCO Warranty), yes the valve body has to be removed for that one.


i'd definitely make sure all the connections to the tranny are good; if all those share a common ground, it may be loose and intermittant. I'd check that.
