  1. General TBSS Questions
    Hey guys, I live in Honolulu and I am looking to get some work done on my TBSS soon. I can feel the shift between first and second is really slow, almost like I'm hitting neutral for 2 seconds between gears. I have also got the intermittent lifter tick I mentioned on my other post. I would be...
  2. 4L80E/4L85E
    I’ve completed the swap but something ain’t right. The wheels don’t spin freely in neutral. While installing the drive shaft I noticed It takes a lot of force to spin. They spin fine without drive shaft so I kno it’s nothing in the rear in. Also tried to turn the trans multiple ways without...

  6. 4L80E/4L85E
    RWD 06 LTSS, after eating MANY "LVL VII" transmissions I have decided it was time to take the plunge. Using the guide from the sloppy wiki, re-pinned at the TCM and the transmission plug. Getting codes: U0100 and U0101. Gear indicator stuck in first, in VCM scanner; PRNDL goes through all...
