Brand new here and have been enjoying reading all the informative posts. I have a 02 Tahoe with a 5.3. Engine is modded; cam, valve train, pistons, rods and I just blew up my 4L60. I'm thinking about a Stage 2 4L80e from Jakes. Long term, I was planning on putting a 7875 .96 A/R turbo on it at some point but my conversation with Jakes last night has me second guessing. They helped me realize that the converter for a N/A vs forced will be different and I have to let them know which direction I want to go when I place my order. So I'm thinking about doing the turbo now and my question is, what should I start with? 4L80e will take 4 weeks to get here and the turbo kit can be here in half the time. I've swapped tranny's before but have never installed a turbo. Should I install the turbo before or after the 4L80?
You don't even need to have a "stage" anything transmission either. A stock 4L80e would handle a turbo no problem, so sourcing a local unit from a wrecker or a dealer/rebuilder could be much faster.
Besides you are limited to around 500-550whp in that truck if it's running the stock bottom end.

Hello,
I have a few questions about the swap:
I have a 07 NNBS, which year 4L80 will work in my truck?
speed engineering is the crossmember I used. I had to cut and reweld mine 1” further back.
email them to make sure it’s the NNBS one.
PM me, I can send the pin out to do yourself on the TCM and round plug. Then buy a new VSS connector and splice in.
mom an electrician. Took me about an hour. Average guy can probably do the same.
I never asked compatibility in years. Just told the builder what year truck I had.
mall in all, a case of beer and a days worth of work.
