After a five week ordeal of wrong parts at the company, two and a half weeks to get transmission, and two and a half weeks for right installation parts, I finally got my transmission in by a professional shop. During this time I had to rent a duramax diesel to move a fifth wheel. Daryl, the owner assured me a 250.00 dollar refund for the truck rental. After mantrans received the core and I asked for a refund, Daryl accused me of lieing about renting the truck. Also the tranny that was supposedly rebuilt and dynoed slips out of all fwd gears under load. The shop that installed say. The shifter forks inside are worn! Terrible customer service! Liars! And thieves. This is a family run scam! I think they are taking junkyard tranny's and painting them, and selling for 1175.00. Please stay away from this company!!!!!
