Can't seem to keep the clutch engaged for some reason. I can go into HPTuners and engage it under the scanner with no issues at all and the truck idles great. Without the scanner override, the clutch engages and disengages every 5 seconds driving down the road. In park, there are no idle issues either, the A/C stays engaged. Pressures are well within operating limits 35/180. I wonder if something in my tune is disengaging it. Any thoughts? Maybe a faulty pressure switch? I know the clutch is good.
