I have a strange problem where this vehicle periodically begins shifting hard but levels out after a couple of days. Approximately 103,000 miles.
Some mods as follows: 3" RT downpipe with high flow cat, 2-1/2" catback, Flowmaster super 40's, CAI, L26 UIM, Intense Polyurethane upper motor mounts (front & rear).
I am not setting any codes and have verified this with two different scanners.
Any ideas would be appreciated.
It'll hammer the planetary gears while doing this too, so watch out, pretty soon you'll be replacing the tranny.
