Decided to put a 4l80 in with new engine. Its a 5.3 bored out to 5.7 with a triple 12 cam Magnum 7675. What stall would you recommend?

Think I am going with performabuilt. They are a sponsor and I liked there email response. I can find negative things on all builders so just going with my gut. If you have a strong opinion not to go with them please share P.M. or post it.

I am switching from a 6l80 and the only thing I know I will need for sure is a harness from pcm of nc. If you know of anything else I will need for the swap please share. Truck is 09 ccsb 4x4. Thanks for any help.

Why give up on 6L80?

I’m not sure you will want to check into the drive shaft length and mount.

I think I byrdman11 did this swap over on his truck.

I am planning on 700whp maybe more and dont think the 6l80 is up for the job. Reliable.

Thanks I'll check into this.

I'll blow mine to bits before I give up. There are aftermarket parts trickling in for them and shops are getting braver. I will give my builder a shot if mine goes boom. My truck is light though, so I know it helps it live...
