This GMC 5500 has a 351 V6 with man. 5 speed
Once owned by Divers Institute of Technology in Seattle Wa.
I am currently restoring with plans to repaint with the DIT colors
Thinking about the possibility installing a BBC 454
At this point the trany id is questionable, on the side if it below and to the right of the New Process logo casted in the case is CS5871 with AE below the numbers. above that is 099 stamped
The service manual calls out a 435GL as standard with 435GD,540GD or a 540GL as options
Have not found info on a NP CS5871 yet, but I have read that the NP transmissions that should be in this rig have reverse to the right and down, this one is to the right and up
any info will help
