Man ill limp your truck to AZ for you if you want to just have the code ran.
Posted on 5/12/13 at 5:54 am to DownshiftAndFloorIt
I certainly appreciate it, but I have to think that they ran a scanner on it at the mechanic shop that did the water pump and it didn't show anything? 
I've seen the local talent at our AZ and I'm not sure they could run it and figure it out either. I could be wrong. Besides, i wouldn't want you spending your Mother's Day messing with my truck today, especially after messing with yours all day yesterday. And regardless of what the code says, I really need to get it towed to TNT tomorrow.
If you had a trailer to tow it to TNT today, i might take you up on that but again, I dont want to trouble anybody, especially on Mother's Day.

Yea the AZ ain't much that's for sure.
Not sure if you're paying to get it towed or anything but I could limp it to TnT for you tomorrow if you want. Drug test at 1 so I'm off.
I can't do it today because I have to finish putting mine back together and figure out what else is wrong with it

I wonder how far you can run one in limp mode without tearing it up? I guess I could try and limp it up there today since traffic would be minimal.
And yes, I am paying to have it towed up there on Monday. $125 I think.
I just figured with me having a feeding tube in my nose and being weak, I didn't need to chance it and have it really break down and not be able to push it out of the road or something.
This shite just all comes at a bad damn time.

How far can I drive it in limp mode?
Will it stay in limp mode or eventually say this is a stubborn bastard and just cut off and leave me on the side of the road?
I'm thinking of saving the hassle of towing it to shop and limping it to TNT today and taking advantage if the light Mother's Day Sunday traffic.
It really just shudders when I first give it the has and then it tops out at about 25-30 mph.

Does the truck just go to 3rd gear and stay?
reason to get mad at shop that fixed water pump"
The TCM may not have been plugged in and or re-mounted properly... the TCM has to be disconnected from the fan shroud to do the water pump if it was not plugged/snapped in properly to the fan shroud, it will(and has happened to many people)fall into the fan blades and cut wires and possibly destroy the TCM...this is a dealer only fix if that has happened...now if it is only the wires messed up, then a shop that knows how to solder can fix the wires...
Next thing I found out, and this is where you may also get pissed at your other mechanic...
(the truck ran fine before getting the water pump fixed right?)
If the cam sensor and crank sensor are crossed the truck will not run, but if the cam sensor is not plugged in it will idle but run like crap when you try to drive it...the cam sensor runs behind the idler pulley that some shops remove as a short cut to make the water pump job easier...he could have unplugged it and not realized it after he put the idler pulley bracket back on...thereby hiding the fact it is unplugged...but seeing as you got a trans code...I don't think it is the cam sensor...
I think the TCM is going to be the problem
Just in case...It would really help if you could tell me if you have a plastic fuel filter or not..
one slim possibility on early LMM's is the drivers door pillar leaks and water runs down the wires inside to the Accelerator position sensor and shorts it out...
But the Trans code is what really is the issue here...I think your first mechanic may have made a costly mistake...

either way...It seems like your original mechanic may be responsible for this...In any case, if any restitution is to be expected, you have to give him the opportunity to correct the issue first...

the TCM mounts to the radiator shroud on the drivers side so it should be easily seen...if it's not there, or has fallen into the fan area, it will be obvious...also after he started it without you there, he may it may have fallen and messed things up and he just mounted it back to the shroud like nothing happened...you may have to trace the wires coming from it(easy) and look for cut wires or fresh electrical tape or wire loom trying to hide the problem...that is if that is the problem...
before you make that call...I would look to see if the hunch is correct...it should be something your wife can do...
one more question that may be relevant...did he replace the belt with a an other than OEM Belt?
Aftermarket belts have been known to mess with the TCM resulting in eventual failure...
sometimes corrected with just going back to an OEM belt...
GM Technical service bulletin in next post...

Here is the GM TSB regarding aftermarket belts...
I hope this could be this simple fix

#PI0310B: Loss of Communication with Allison TCM, Intermittent Transmission Hesitation, Reduced Torque, Range Inhibit, Clunk, Stuck in Gear or Neutral, Wont Shift, DTC P0880 and/or U0101 Set - (Dec 2, 2011)
Report this image
Subject:Loss of Communication with Allison Transmission Control Module (TCM), Intermittent Transmission Hesitation, Reduced Torque, Range Inhibit, Clunk, Stuck in Gear or in Neutral, Won't Shift, DTC P0880 and/or U0101 Set (Inspect for Electrostatic Discharge (ESD) From Aftermarket Serpentine Belts and/or Added Equipment, Install OEM Belt, Relocate TCM)
Models:2007-2012 Chevrolet Silverado
2007-2012 GMC Sierra
Equipped with Allison® A1000 Automatic Transmission RPO MW7
Attention:Please review the latest version of Corporate Bulletin Number 04-06-04-054B: Info - Non-GM Parts and Accessories (Aftermarket), for information regarding GM's policy on the use and installation of aftermarket components.
This PI is being revised to add G102 information to the Condition/Concern and Recommendation/Instructions. Please discard PI0310A. The following information may be helpful if the vehicle exhibits the symptoms described in this PI.
Condition/Concern
Some customers may comment that the transmission will intermittently hesitate, clunk, gets stuck in gear or in neutral, won't shift, or experience reduced torque or range inhibit.
The technician may observe on a scan tool DTC P0880 and/or DTC U0101 set as Current or in History.
This condition may be caused by:
• Resistance in the G102 ground connection on the side of the engine block.
• During normal servicing, the OEM General Motors serpentine belt was replaced by an aftermarket serpentine belt.
• An aftermarket serpentine belt was intentionally installed, due to dimension changes from added aftermarket equipment such as a second alternator or clutch pump installed by an upfitter.
Certain brands of replacement aftermarket serpentine belts are made of compounds that will reduce the opportunity for audible belt noise, however these compounds can generate significant amounts of electrostatic charge on their surface. This electrostatic charge can discharge and cause DTC P0880 and/or DTC U0101 to set and be accompanied by any of the above symptoms.
Recommendation/Instructions
Important: DO NOT replace the transmission control module (TCM) until the root cause of the problem has been properly resolved. The TCM ONLY NEEDS to be replaced if it has incurred permanent damage, such as hard failed codes, complete loss of communication or other erratic behavior that continues to exist AFTER completing the following steps.
1. Perform the Diagnostic System Check - Vehicle.
?If DTC P0880 and/or U0101 are set as Current or in History, and/or the above symptoms are observed, proceed to Step 2.
?If DTC P0880 and/or U0101 are not set as Current or in History, and/or the above symptoms are not observed, refer to > Transmission > Automatic Transmission - Allison > Diagnostic Information and Procedures in SI.
2. Turn OFF the ignition.
3. Disconnect and inspect the G102 wire terminal and connection for looseness and corrosion. Clean any corrosion from the wire terminal and the surface of the engine block with a wire brush.
4. Apply dielectric grease to the wire terminal and engine block surface. Connect the G102 wire terminal and secure properly.
5. Inspect the engine for an aftermarket serpentine belt due to service replacement or added aftermarket equipment from an upfitter.
?If an aftermarket serpentine belt is installed on the original serpentine system, without added aftermarket equipment installed on the engine, replace the serpentine belt with an OEM General Motors serpentine belt. Refer to Drive Belt Replacement in SI.
?If an aftermarket serpentine belt is installed because of added aftermarket equipment installed on the engine, proceed to Step 6.
