ok everyone i need help
last nite i was drivein down the road and was in high gear. i was just cruzeing and the truck just started to shake. so i stop and started back up the road again. and when i got into high gear it did it again. it feels like tourqe converter shutter but ive never seen any proplems with the converters in the allison before. yawl have any ideas????? and if it is a converter what would be the best to put in it ive been thinking about puttin a new one in it anyways, i wana be able to turn the progammer up "ppe standerd" to lvl 5 and not break anything. because ive heard the trans will hold it but the converter wont.

thanks,
craig
