Sonnax 34994-02K Transmission 1-2 & 3-4 Shift Valve Spring Kit 4L80E 91-18

Description: 4L80-E, 4L85-E Transmission 1-2 & 2-3 Shift Valve Spring KitPart No. 34994-02KIn 4th Gear, signal A oil force must overpower the 1-2 shift valve spring and opposing signal B pressure in GM 4L80-E and 4L85-E transmissions. If the 1-2 shift valve does not remain fully stroked, drive oil to second and direct will be cut off or go to exhaust. The reaction area of A is greater than that of B, so the spring is the stroking factor. Complaints of 2nd Gear starts, Neutral after 2-3 shift or no 4th Gear are compounded by worn AFL limit bores, leaking O-rings and solenoids. When AFL oil drops, and signal A becomes less than 58 psi, the 1-2 valve will stall or float. This 3-1 or complaint of 3rd Neutral will occur in OD or D with scanner indication of 4th commanded.
