Hello,
On my 1996 GMC with 5.7L Vortec, 4L60E and 3.73:1 rear gear. I attempted to conduct a crankshaft relearn more than once, I still get a 1336 DTC code. These are the steps I took to do a crankshaft relearn; E brake, foot brake, start engine, accelerate to fuel cut off, let the RPM's fall and cycled the switch. Did I miss a step?
Thanks in advance.
