has anyone heard of this company 'man-trans l.l.c.'? i'm looking to do the t-19 swap to a zf5. this company gave me a price of 2000.00 to my door, for a zf5 remanufactured with no core. what do you think? one other thing, i called luk, they were no help. the tech guy didn't seem to understand the swap. and just told me that they didn't have anything for that swap. whats that about? this is for my signature truck.
