I think my TCC solenoid is failing, but I want to get opinions on it before I rule out other possibilities.
First, there are no codes set - history or current.
I was driving along on Saturday at about 45 MPH, with steady throttle I began climbing a hill and the car began 'jerking'. It felt like it was switching between 3rd and 4th gear, but after some experimentation I'm pretty sure it's the torque converter locking and unlocking. It only happens above 35 MPH and only in 4th gear. If I drop it to 3rd the 'jerking' stops. If I let off the throttle (thus letting the converter lock) it stops. If I give it some more gas (thus unlocking the converter) it stops, too.
I read the TSB and it seems to address a situation where the TCC soleniod has stuck shut, thus locking the converter as soon as the fluid path permits (4th gear?) causing harsh up and down shifts. Mine is acting like it's failing, not stuck.
Could this behavior be anything else? I'm thinking not, but you never know.
If it is the soleniod I'm going to limp it along until spring. It's getting too cold to take the engine/trans out of it.
