Replacing Shift Solenoids Diy

[Berry]

4L60-E tranny threw a DTC PO753 code: 1-2 shift solenoid elec malfunction. Want to change this out myself, Is this a simple R&R solenoid or are there more technical aspects to it?

It can be time consuming, (lots and lots of labor) but should be straight forward, however you are going to have to get to the part in order to change it out, may require removing other parts.

Looks like a piece of cake...

[Norseman]

That might just be worth just paying someone (that knows what there doing) to do it.

First diagrahm might be do able, the second one is a little scary

Thanks for that diagram Mike.
