I bought my 2005 Chevy Express 3500 Van (Cargo) last May with 104k miles. I had the Transmission flushed last November, at the advise of my trustworthy mechanic. He has done me well in the past. This past Thursday with 108k i get a check engine light and the code is P0894 Transmission component slipping. In Jan of 2015 I blew the transmission on my 99 Chevy Silverado. now down 2 vehicle. I use the Van in the evenings and on Weekends for my Electrical business. Any help or advise would be greatly appreciated. I am think i need a new 4L80E tranny and Transmission Cooler.
Thank you. Eric
