I have an issue with my ignition hanging and I have to tilt the steering wheel to get in the off position. I have used a great key lock spray and it doesn't help resolve the issue. Is this an ignition assembly issue or something else. If anyone has a past experience with this please advise.
Thanks

This is a terrible GM warranty experience, two months waiting for a covered engine swap with no loaner or timeline is not allowed under GM’s courtesy transport policy.Escalate straight past regular support to a GM executive case manager, document every closed service ticket and dealer repair paperwork. File a complaint with NHTSA to force faster action, and ask for daily rental reimbursement while your truck is down. If it’s been out of service over 30 days, your state lemon law may let you pursue a full vehicle buyback.
198°F isn't unusually hot for an 8L90, so I don't think temperature alone caused the issue.
Since everything returned to normal after the truck sat for several days, I'd be looking at an intermittent electronic or hydraulic control problem before assuming the transmission itself has failed.
The first thing I'd do is scan the Transmission Control Module (TCM), not just the ECM. GM transmissions can store manufacturer-specific or history codes that won't trigger a check engine light.
I'd check:
TCM history and pending DTCs
Commanded vs. actual gear
Line pressure
Shift solenoid status
Torque converter clutch (TCC) slip
Transmission fluid temperature
If it happens again, try to capture the data before cycling the ignition, since some intermittent faults disappear after a restart.
A professional scan tool that supports full GM transmission diagnostics makes this much easier. For example, the Foxwell NT809BT can access the TCM, read manufacturer-specific transmission codes, and display live transmission data that's not available on a basic OBD-II reader:

Hopefully it's just an intermittent control issue, but I'd definitely pull the TCM data before replacing any parts.
The 92-95 SCPI spider injectors are notoriously problematic and hard to source new replacements. I’d pull the intake manifold first to inspect cracked lines and brittle plastic legs before dropping $350 on a rebuild. The 1.5 OBD system only offers limited data, no misfire tracking, which is normal for this 1995 model. Enjoy the project!
