Job of truck and how it relates to TCM

[Bigleb33]

So whats the difference with the Jobs 1,2, and 3s is it the TCM's? My truck was built in Aug of 07. So what does that mean.

Thanks

It could be a Job 1 and it could be a Job 2 I believe. I think Job 2 starts after July of 2007, but I can't remember for sure. There are Job 1 trucks with November and December of 2007 build dates. Basically the issue is that if you have a Job 1 TCM, you really need to have the Spartan TCM on your truck if you plan on running the 310 tune.

If you pm me your vin number then I can tell you what job your truck is. There are a few differences between the job 1, 2, and 3 but as far as tuning goes the TCM is the biggest thing. Job 1 trucks just don't hold up as well with the higher tunes and the shifting is a lot harder. Need more information on it just pm me!

They aren't as good for tuning.

the Job 2/3 trucks have upgraded hardware(wiring) that allow more current to get to the shift solenoids for more possitive engagement under higher hp applications.
