Already saw it, wont work for me; I am all 24x

 

Oh well free bumps for OP GLWS

 

@arthursc2 needs the SIM version for gen3/24x.

 

I have the Zero Gravity TCM-2650, I should be set! I am not familiar with the SIM version of this product, but I am willing to hear about, I have other vehicles that might need 6spds

 

What about those of us that have a 03-07 24x truck? Is there an option for us?

 

Yes, read the post above yours
