I have a 2003 1500 express and. It has a 5.3 with a 4L60. I have a 2010 1500 Silverado z71 that has a 6.2 and the 6L80. I want to know if I can take all of the drive train from the truck and put it in the van and put the drive train from the van into the truck and what it will take to do it.

 

I'll say this first, it's not worth your time or effort to even do a swap like this.


The 2003 VAN is a 24x system running a P59 controller with no CAN-BUS. The 2010 trucks runs a 58x system using a E38 with CAN-BUS.

The VAN computer can never run the 6.2 and 6L80e combo nor can the truck computer control the 24x 5.3 and 4L60e that came in that year van.


You would have to swap the complete drivetrain, harness and computer from the truck and stick it in the VAN, then tune it and make it run. A custom gauge setup would be required because the E38 uses can-bus with the BCM to control the inside electronics.

The van engine/transmission would be a cluster **** of random parts you'd have to buy to even make it work in a GEN 4 applications. Lots of wasted money spent to even get it to run.

 

Or steal components from a newer van

 

I helped a friend swap a newer model engine into a Blazer once. I think it was the pre 99 to post 99 style. It required a lot of rewiring, pcm swap, cluster swap, and random ****. In the end it was NOT worth it to get about the same performance as before.
