My A/T (700r4) shifted late and mushy. TV cable adjusted properly (self adjusting style with ratchet thing at carb). Fist thing I did was get a governor spring and weight kit, put it light springs and weights. Helped the shift timing but still mushy. Then I bought a Corvette servo, that really firmed up the shifts but the 1-2 shift now comes in late under light to normal acceleration. Thinking I need to play with the governor again but I don't understand the relationship between the weights and springs. Is it somewhat like a distributor, where the springs control the rpm and the weights control the curve?
You can also tailor individual shift points by changing 1-2, 2-3, 3-4 shift valve springs in the valve body. I found this, might help. https://www.thirdgen.org/forums/transmissions-drivetrain/267954-700r4-governor-weights-springs.html Sent from my SM-G973U using The H.A.M.B. mobile app
