Would anyone have the inside scoop on gear availability and torque converter lockup with the 6L80 transmission. Specifically --

* In tow/haul mode, which gears are available?

4th at 1.15 ratio

5th at 0.85 ratio

6th at 0.67 ratio

* In tow/haul mode, which gears does the torque converter lock up on?

* In normal mode, which gears does the torque converter lock up on?

Thanks!

  You are correct - I was mistaken. I'll have to see on my neighbors truck. You're probably right, but it does look rather short.

  I haven’t gotten the engine broken down yet to determine exactly but I do know the cam is done and there was misfire in 2 cylinders. While driving; check engine light blinking, stabilitrak flashing on and off and the oil PSI jumped to around 55-60 PSI. This of course after I had to deal with the 8L90 shudder that the dealer couldn’t figure out so I fixed that. If I keep the truck a built L8T is replacing the L86. The DoD/AFM kills these engines.

  I have the later version of this where it bypasses the radiator and only goes to the AC Condenser. I also have Speed Engineering true dual exhaust with their long tube headers. My trans got to 220 today as the 3" crossover pipe that runs directly under the trans pan is about 1mm away from it. I also have the Sure cool mod done. Had anyone installed a tru-cool 40k or mishimoto trans cooler? IF so, did you bypass the factory cooler or just run it inline after the factory cooler? I need to get these temps under control.

  There's also this one if your truck is like mine and started having really hard upshifts from 7th to 8th gear. https://static.nhtsa.gov/odi/tsbs/2024/MC-11010466-0001.pdf
