Shift A solenoid location in 4L60E transmission
Roy
the pan is dropped. My question is, where is it located and how do I
tell it from the Shift B solenoid? I have a 96 Suburban K1500 5.7L
with 4L60E tranny.
TIA!

Since everyone said they are easy to replace I tried it. The P0753
code I was getting indicates Shift A Solenoid (electrical). This one
shifts from 1 to 2, or 3 to 4, depending on the state of Shift B
solenoid. The dealer has 3 shift solenoids indicated, all with the
same part number, but there are only 2 solenoids for basic gear
shifting. The dealer asked if I needed the 1-2, 2-3, or 3-4 solenoid.
1-2 and 3-4 are the same thing, and the one that I needed. I still
don't know how to tell which is which, so I replaced both. They are
inside the pan. I put a drain plug in the pan the last time I replace
the fluid, so it was a very quick job. The shift solenoids are at the
front of the transmission valve block, which is almost as big as the
pan and is what you mainly see when you remove the pan. Remove the 2-
wire connector to the solenoid. Then there is a wire clip holding each
solenoid in. Pull the clip down toward the ground to remove it, and
the solenoid spring pushes itself out. Be aware that more fluid will
drain when the solenoid pops out. Replacement is just the reverse.
Make sure the solenoid is pushed *all* the way in, flush with the
valve block.
