Can the valve body (main control) be removed and replaced/rebuilt without removing the transaxle?
1999 Mercury Sable 3.0L 24V engine 135,000 miles Harsh 1-2 shift Other shifts are smooth No leaks. Runs fine Have changed fluid and filter No slippingI have researched this problem and it seems common. "Simple" fixes appear to be to replace valves and springs in the valve body. There is also a 1-2 Sonnax accumulator upgrade. All designed to fix harsh
1-2 shift. I bought the ATSG manual.My question is, has anyone tried this before? Do these fixes improve anything? Can they be made without removing the transaxle for the car? I am researching only at this stage.
Thanks!
