Ascender 2WD V8-5.3L (2004)
1.
Using the exploded views shown inspect each bore for freedom of valve(s) movement and evidence of debris. Pay particular attention to those
valves related to the customers concern.
2.
Verify movement of the valves in their normal installed position. Valves may become restricted during removal or installation. This is normal due
to small tolerances between the valves and bores.
3.
If a valve is restricted and cannot be corrected by cleaning the valve and bore then replace the valve body. Describe the restricted valve on the
repair order.
NOTICE:
Be sure all solenoids are installed with the electrical connectors facing the non-machined (cast) side of the valve body; otherwise the solenoids
will bind against the transmission case as the valve body bolts are tightened and damage may occur.
Disassembly/Reassembly
1.
If a valve is restricted by a metal burr from machining that bore remove the valve and burr, then inspect movement in the valve's normal position.
If no other debris or restrictions are found then reassemble the valve body and install in the transmission.
