Vehicle make/model 2004 chevy impala
Mileage = 170,000
Engine size = 3.4L
dash lights = check engine light
codes = shift solenoid A
work done prior = not available
work done to repair = not available
tech = SF
question = I got this code out of the OBD2 and it says shift solenoid
A. I assume this is the on/off soleniods located in the valve body?
Which one is A when looking at the valve body. I have not pulled the pan
yet. Is it hard to get off? I have a lot of experience swapping engines
and transmissions, just don't know for sure if this will fix the issue
or not. The fluid is a little dark like the tranny has been slipping and
it does not shift quite right(slips sometimes). Did I catch it early
enough or am I going to have to replace the whole tranny? Thanks for
your help and will give donations when possible.
SF:
Assuming no debre in the pan, and no other codes, then 1-2 shift solenoid should fix condition,
although this car has a lot of miles on it.
In order to get to solenoids, the trans. side cover will have to come off. This entails supporting
the engine/trans. assembly with support fixtures on top.
Lowering the left side frame per manual instruction. IE- disconnect ball joint, steering shaft, axle,
trans. side mount, shields, brackets, harnesses, etc.
The 1-2 shift solenoid is on the left side of the valve body, middle way up.
