WARNING: This part only fits PWM units, and mismatching PWM and non-PWM valves will cause rapid converter failure:
Identifying PWM vs. Non-PWM Units If the OE valve features one spool at the location indicated here, you are working on a PWM unit. If the OE valve features double spools, you are
working on a non-PWM unit and must use Sonnax TCC Apply Valve Kit 77805E-K. Do not rely on the OE valve material (steel vs. aluminum) to determine
for whether the unit is PWM, as some early PWM pumps used steel TCC valves like the non-PWM pumps.
