Need help on my trans

[Dean jones]

Hey y'all new to this forum but I’m looking for some help, I have a 2006 Chevy Silverado 1500 4x4. I have a ls1 swap with big cam ported heads/intake, performance plugs, wires and coils, 32lb injectors and 1&7/8ths long tubes ran to a 3in true dual, so I blew the trans again was a “stage 3” trans about 2 months ago 1-2 and 3-4 bands and clutches where destroyed. I just had had the trans rebuilt again lmao (4l60e) swapped it back In and for some odd reason it won’t drive. The truck will just stall out after going into gear. Another note is the torque converter is a brand new circle D 2800-3000 stall. Now what I’ve done to narrow things down some, I replaced the TCC solenoid as-well check all the wiring. No codes pop up when I scan other than a MAF code. I honestly don’t know what else to check trans shop said it could be the converter so I pulled it and had it checked out nothing wrong internally. so any help/advice would be greatly appreciated. Thank you in advance

Welcome to the forum from Oregon.

My one and only guess would have been the converter or what it locks in to. Nick at Nickstransmissions is very good with these transmissions.
