I'm close to swapping my 4.3 for a pure-stock LQ9 I've bought, so I just spent my evening researching transmission options, can anyone confirm the FLT level 3 will live with a stock LQ9 towing up to 6500 pounds, but no racing, nitrous, or other abuse? Until tonight, I was a Bowtie Overdrives believer, but it seems the FLT is now the right company for me. It's going in an '06 RCLB 2WD WT 1500 with few options, and 4.10:1 gears, and 245/70R17 tires
Penny for penny, you're better off swapping to an 80e. Especially towing and such. It is a very straight forward swap for you. I really don't know anyone who just goes for a level 3. Normally people get the 5 or 7.

Thank you for being willing to type what you felt would be helpful, but it doesn't really directly answer what I'm hoping to find out.
To all future responders, a 4L80E is NOT happening. The TCI 6X is too costly, plus would require another axle ratio change, this time going back to a 3.73:1 gear.
does anyone from FLT ever log in here? I'm looking at a combined weight of around 11,000 pounds dry. Not very much. In fact, adding the GVWR of pickup and trailer comes to only 14,000. Not a serious load. Stock 4L60Es are rated to do that with a 5.3L.
Call them they are always willing to help to get you where you need to be Andy is who will probably answer and his customer service is second to none,all the builders there know there shit. I personally have a 4L65 lvl 5 and I love it ,every part they say there putting in is there and I know that for a fact .they go above and beyond where others won't if you go FLT I can promise youll be happy and I'm not affiliated with them in any way I'm just a very happy customer
If you honestly don't mind dropping the dough on one, then go for it. I have a FLT 4L65E and I have been driving mine for 2+ years with no issues.

I sent a PM earlier this morning, and already I have a reply. It basically says that since GM chose the 65 over the 60 for the 6.0, that's why I should go level 5. It occurrs to me that the elevation I live and drive at affects engine output, so I researched that. It seems I lose 4% per thousand feet. I live at 4500 feet, so I'm losing 18%. So, 380 ft-lbs times 0.82 is 311.6. That's right between a 4.8 and a 5.3. A level 3 should do. But I want to tow to the Olympic mountains, ( among other places, ) and the base of those is near sea level.
Looking at FLT's info, compared to level 4, the level 5 adds a billet 4th gear servo, but I don't tow in fourth, ever. It also adds 5-pinion carriers, which aren't needed below 450 ft-lbs.
Anyone comment on a level 4 with an LQ9?
