Hi- New to Truck Stop. Have a 1994 GMC C1500 2WD 5.7 whose 4L60E is acting up.
Fairly sure it's a grounding issue, or no power to trans due to ignition switch (common anomaly). DTC 66, 67, 81, 82 all at once. Extremely hard to believe all solenoids would fail at same time.
Need ground locations for this vehicle- have been poking around with multi meter and somethings not right.
Please, if there's a sticky on these matters, let me know.
Thanks a bunch!... see ya in the forum.
