It happened on my H2, it turned out the wiring harness fell a bit and was laying on the tranny and wire got hot and melted. That was one time, the other time it happened to me it was the clutches in my tranny 4, 6. Yes, its happened 2x to me, I rebuilt my 6l80e to a stage 3 tranny now its...

Just put this on my 2009 H2 bcuz I put in 4.88 gears so I upgraded a lot of other things

Hi everyone, I'm new too but have been upgrading my H2 to 2022 this year lol. Put in a new l9h motor, re-did the l680 tranny & xfer case, driveshafts etc, put in all that kryptonite had to offer, and just put in a magnuson supercharger and 4.88 gears and had RCL in Pennsylvania make custom axles...

I have 37x13.50x22 and there's a smidge of rubbing at full lock. I've got my keys set for 2" higher to level it out and its rides great. I also put in custom axles from RCV in Pennsylvania and Kryptonite front end everything they make and put in 4.88 gears

Hi Everyone, I've got a H2 that has 37's so I'm going to install 4.88 gears in about a week and get it re-tuned / programmed for the gears. I'll post a picture of it shortly
