When I get the shudder it is usually in 2nd gear with the TQ converter locked and the TC showing a value of 5. Whatever that is??

Torque Control Mode 5 = Spark Cut for Tip-In Shock Control

Here's the full TC Mode definition list:

00: No Torque Control Requested
01: Fuel Cut for Low Line Pressure
02: Fuel and/or Spark Cut for Traction Control
03: Fuel Cut for Speed Control
04: Fuel Cut for Rev Control
05: Spark Cut for Tip-In Shock Control
06: Fuel Cut for Decel
07: Spark Cut for Transmission Shift Contol
08: Fuel and Spark Cut for Excessive Engine Oil Temp
09: Fuel Cut for Excessive Engine Coolant Temp
10: Disable Current Torque Mode to Prevent Stalling
11: Fuel Cut for Turbo Control
12: Fuel Cut for Anti-Theft
13: Spark Cut for Tip-In Engine Lugging
14: ETC - Electronic Throttle Control only

Keep in mind that only highest priority (lowest number) TC mode takes precedence.

My guess is that what you're feeling might be related to a timing issue. This may also have something to do with the backfiring issue. Let me know which tunes this is occurring on and I'll make some changes to the timing tables which I think should resolve the problem.

Take care.
