Seafoam transtune miracle
Been experiencing hard shifts from 2nd to 1st, and especially in the cold. Feared the worst, and I had planned to replace the 13 pin conductor and maybe even the (complicated) conductor plate.
But then I remembered reading some very positive reviews about seafoam transtune. So I went to advance auto and purchased $10 bottle. Siphoned out a bit of aft to avoid overfilling and poured entire bottle into dipstick.
Day 1. Immediately I noticed smoother shifting but didn't know if it was just in my head. Later in the evening I drove the car again and still no hard shifting.
Day 2. The real test would be whether the hard shift would occur in the morning as it has done all winter. To my pleasant surprise, there was no hard shift at all. So far so good and guardedly calling this product a small "miracle". Will follow up on subsequent days with a longer term review. Fingers crossed! Planning to drive the car a few hundred miles and then drop the pan for a full fluid and filter change as well..

I had a radiator internal leak so causing transmission fluid and coolant to mix.
After replacing the radiator and flushing the transmission and replacing filter several times, it sometimes jerky when slow down to 20 mph and speed up again. Only once in a while not all the time.
I put in a bottle of Seafoam and it's normal now.
