hi, i recently picked up a m 1070 het and i am having issues with transmission. we found this out when trying to move it to get it loaded after purchase. it has the allison CLT754 . the transmission moves good in forward but reverse it barely will move. the transmission looks like the rear section of trans has gotten so hot the tan paint turned pink. anyone have any experience working on the allison of this size. i am in the process of removing trans now. thank-you for any info.
