Silverado P59 TR6060 swap cruise control

[Snobody]

Hello all,

I have a 2006 silverado 1500 factory 4.8/nv3500 truck. 4.8 has replaced with a lq4 6.0 and swapped to a tr6060 from a 2011 camaro ss. Precision 7675 and 2 bar OS conversion. My issue is that cruise only works in gears 1-4, not 5th or 6th. Speedo is accurate, truck has 4.10 gears and 31.5" tires. Ive calculated the vss pulses per mile and output pulses multiple times to no avail. The cruise did work great up until the 6 speed swap, even after the 2 bar os conversion. Anybody had this problem before? dfco adjustments failure.hplDfco, tire change 61825.hpt

Computer is looking for rpm vs mph according to the gearset in the transmission segment you used. Unfortunately the gear ratios in the trans are not adjustable in hptuners. I've heard there are other ways but not sure how it works. I just used the pull down menu and changed mine back to 4l60e to get cruise to work. However, it did introduce some startup flare and rolling idle issues I haven't solved yet.

Changed it to 4l60e and no prndl equipped. Cruise works now but dosent recognize clutch switch. Did you have to jump some wires or change something else in the tune?
