At first I was gonna ask if you got it done at Cottman Transmissions in Olathe, KS. I had the exact same issues, drove it off the lot after dropping $2500, slipped off the lot. Brought it back.... yadda yadda yadda.... got it back 2 days later same cold slip. Brought it back and they "fixed" it. 11 months and 13k miles later, tranny goes. Sucks for me I only had a 12month/12k mile warranty. I bought a Certified Transmission and have had good luck. They had to warranty it once, their was issues with the TCC.
