Certified Transmission 7203538252 Failed to Deliver as Promised Commerce City Colorado!!. I ordered a transmission from a listing on craig’s list. This character I believe his name is Jeff agreed to sell me a remanufactured transmission and told me he would be in Cheyenne WY between 5 and 6 pm that night. He asked me to bring the old transmission as he needed the core. I live in Casper Wyoming I offered to pay $600 for the reman 700R4 and the offer was accepted. I drove to from Casper to Cheyenne to complete the deal. Called Certified Transmission when I got to town and was told that they didn’t load the 700R4 and only delivered to shops. I asked where I could go to pick up the transmission. I got a text back from 7203538252 telling me that they were going to pass. I strongly suggest that you pass on dealing with this company/individual.
