Well, so far I've replaced the fuel pump, the battery and alternator, changed the oil, replaced all 4 tires and wipers, the exhaust resonator and now it runs well, but chunks in and out of gear when you get on or off the accelerator when it gets warm. So far, i've bought a couple of jugs of 3309 and some SeaFoam TransTune and I'm replacing both the upper engine mount and lower torque mount, ( both completely gone) and expecting to have to replace the linear solenoids.
Car has 139K on it and it was parked ( not "stored", but parked) 5 years ago. This is NOT a good thing.
Here's my question: Do you think my tranny problems might be due to sitting so long with dirty transmission fluid ?

 

That could easily be why it was "parked" 5 years ago.
