Thanks for the heads-up Neil. I actually received an e-mail from "ChevyMatt396" from the same message board. He sent me the full info on the fix earlier in the week before it was made a TSB. I guess I'll take it to the dealership. <img border="0" title="" alt="[Sad]" src="gr_sad.gif" />

<strong>What do you mean by shutter?</strong></font><hr /></blockquote><font size="2" face="Verdana, Helvetica, sans-serif">With my truck under part-throttle, I feel a shudder/shake on the 1-2 shift. I always wondered about the line pressure because the 1-2 shift is always harder than the 2-3. Under WOT or even 1/2 throttle, the shudder doesn't happen.

 

is this something i should add to my list of **** to get done to the truck THIS weekend? is it urgent or if i let it go for a while will everything be ok? this should be covered under warranty too right?

 

That is soooo last month! <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" /> Some of these connectors the average person cannot get ahold of. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

Correction:

Install an external sense lead to the generator assembly. This is accomplished by adding a wire from the generator four wire connector to the generator output BAT terminal.

Disconnect the negative battery cable from the battery/batteries.
Slide the protective boot on the generator BAT terminal aside and remove the retainer and wire cable from the BAT terminal.
Unplug the generator 4-cavity terminal from the top of the generator.
Remove and save the orange weatherpack seal and CPA from the 4-way connector.
Using the proper terminal removal tool, remove the two wires from the 4-way connector.
Install a red cavity plug, P/N 12059168, into cavity "A" of the new 4-way connector, P/N 12186568.
Install the brown (Circuit 25) wire of the vehicle wiring harness into cavity "B" of the new 4-way connector.
Install the gray (Circuit 23) wire of the vehicle wiring harness into cavity "C" of the new 4-way connector.
Obtain a piece of 0.80 mm/18GA black wire, 254 mm (8 in) long.
Install a red terminal seal, P/N 12048086, and terminal, P/N 12048074, (crimp and solder) on one end of the new black wire.
Install the new black wire into cavity "D" of the new 4-way connector.
Reinstall the connector seal and CPA, from the original connector, to the new connector.
Plug the 4-way connector into the generator.
Route the black wire to the generator BAT terminal, sliding the wire into the small end to the output terminal boot, along side the generator output wire.
Crimp and solder the ring terminal, P/N 02977821, on the open end of the new black wire.
Place the generator output wire and the new black wire onto the generator BAT terminal and install the retainer. Tighten
Tighten to the BAT terminal retainer to 9 N·m (80 lb in).

Connect the negative battery cable. Tighten
Tighten the battery cable retainer to 17 N·m (13 lb ft).
