Wear at the inboard/balance circuit causes high throttle pressure and late upshifts. Wear of the OE valve or the bore at the V metering groove circuitcauses sensitive 2-3, 3-2 shift timing. Wear at the sleeve area reduces throttlepressure and causes early shifts.
The Sonnax oversized valve and plunger restore proper clearances to prevent cross leaking and throttle buzz.
Common complaints with Chrysler FWD 3-speed units are shift timing concerns, throttle buzz, poor kickdown and/or early upshifts caused by throttle valve and bore wear. These complaints are caused by bore wear and the valve body typically has to be scrapped. Sonnax offers an oversized TV repair kit, 32229-01K, to salvage the valve body and restore throttle valve control by oversizing the bore and replacing the valve with an oversized version that restores proper clearances.
