shift point for an auto fc
 

What are the shift points on an auto fc underload and wot

well. depends .. as s4 is vac modulated .. s5 is electronic shift

S4 for sure n/a

86-88 FSM.. section 7.. page 24

Thank you

After trying faq , all links for s4 fsm are down . the hard drive on my computer is fried where I had the FSM , so now I can't look at it anyone got a dig copy ?

After replacing vac modulator , still shifting first to second at 4600 rpm

No 4th shift either . What is the electronic device next to the modulatoe valve ?

Kickdown Solenoid.

Anyone have in depth experience with autos for the s4 ? I have a complete T2 with 5 speed , I dont have the time for the 5speed conversion yet however . Dailying the s4 na until my a4 doesnt cost me 180+ a week to drive

after unplugging the solenoid at shift at the proper ranges . how the solenoid affect shifting other than the kickdown on full throttle

sounds like the kickdown valve inside the trans valve body is stuck partially open. This can cause the issue you are having.
