Tranny failing? Torque converter?
Hi all, hoping to get some info on my tranny symptoms.
Stock for the most part
half ton - NO TRANNY COOLER
Tranny fluid level good
No tranny odor
Metal shavings on trans input speed sensor magnet when removed
Recent Work Done (tranny related):
Tranny flush + filter (2 yrs)
Trans input speed sensor (code 74)
New flex plate and starter
Wastegate solenoid (no idea if intermittent loss of boost messes things up)
Regularly - lose torque converter lockup, no cruise, need to re-start vehicle and back to normal
Previously - torque converter locks, unlocks, locks, unlocks, etc. Solved (I think) by trans input speed sensor/WG solenoid
Previously - the first torque lockup of the day on the highway would sound like I'm going over highway rumble strips for 2-3 seconds (the ones that wake you up)
Rarely - hard shift 1-2, vehicle needs re-start and shifts OK
Rarely - vehicle chatters/shutters when taking off from a stop (high heat)
I hope this is clear. Lots of things going on, tough to explain over the internet but let me know if you guys have any insight.
