Given the cost of rebuilding an Allison, I would be very leary of having the TCM replaced by anybody other than an Allison ASC. If you are being told the "junk yard" TCM will need to be "reprogrammed" anyway, why not just go to Allison dealer and hold them responsible to do the job right the first time?

OBTW, there are Allison specific and Workhorse specific forums also here on iRV2.com

Something broke in the Allison in my 3500 GMC. Nobody could touch it as Allison seems to have a strangle hold on the transmissions. I got a Allison reman for $3500 installed at the GM dealership. You may be able to find a whole unit at a salvage yard, but the price would probably make a reman more attractive. At that time, we were planning on a big honkin 5er so the best solution for durability was the best solution for us. A 36K / 36 month warranty was given. The 36 months have long passed, and the truck will probably never see the 36K miles.
