Ok I went to Autel 

https://www.autel.com/mk1/3262

I do not believe your code reader is capable of reading any codes but Powertrain-P codes.  I trust that the transmission control module falls under P codes.  But Body and Chassis codes are not pulled have you seen body or chassis codes?   I don't think it is pertinent in this instance, but just be aware that without the B and C codes you don't have an entire picture going forward.

An example of C codes, these can cause Traction Control issues.  

ABS
C1217 Pump Motor Shorted to Ground
C1248 EBCM Turned the Red Brake Warning Indicator On
C1298 PCM Class 2 Serial Data Link Malfunction

i am still trying to figure out why your engine torque is negative and what that means.

Not related.  I think its related to retarding the ignition and or dropping cylinders to lessen engine torque.  

Here is a good description

I clicked on caddy forum link I read it all.  It was so much to try to think abt all at once so can you tell me what that forum could mean Is it possibly any of those? The pcm on my car doesnt shut any of the cyclinders off though. It idles fine. Forgot to mention my air fuel ratio is off to says obd

That wasn't to overwhelm you, it was to understand negative engine torque and what might cause it. Are you getting the wheel speed sensor code from the Autel?  

Send me the screen shots.

Ok, I received the screen shots.  The P codes or anything that states NOT RUN, are not an issue yet because the PCM test was not completed.

The thing that REALLY concerns me is this code U0101 lost communication with TCM (transmission control module) see photo.  

I did a search, now I KNOW, this is a totally different year, engine and model BUT, look at his symptoms...  it sounds very similar "It was trans slip city!! I tried to avoid as much slipping as possible and managed to reach about 30 mph eventually. Work was only about 1 mile away."

See this link

https://www.cadillacforums.com/threads/dtc-u0101-lost-communication-with-transmission-control-module-2008-sts-3-6di-at.702001/

We need to find out why you have the U0101.

Lets rest on this, charge your battery with a charger, many codes can be caused by a weak battery.  

Many of these tests can not be run because the car isn't moving, but you have a ton of codes that need looking at if they persist.  The wheel sensor and O2 sensor comes to mind.  

Where are you located?, has this car passed the state inspection?

Good night, I think we made progress

If and when I did clear those codes they didnt come back besides the trans fluid life the wheel speed sensor cpl more but I'll run obd tmrw with cleared codes n send you what I get.  Tennessee and I bought it off a old cpl when it had 85,000 miles on it. Never had no test . As far as 02 and wheel sensor I can replace those tmrw

Don't do anything.  The U0101 must be researched and diagnosed.  Codes are KING, codes lead you to the problem.  Parts replacing i.e. replacing the shift sensors and VSS was unnecessary and you are speaking about replacing the pump, no, don't do anything.  We made progress, the U0101 is a key here given the experience of the fellow at the above link who described SLIPPING, exactly what you have.  Shaun, I am beat here, lets rest on this.  I responded to your PM also.  Mike

Then lets do that.  But make sure the battery is 100%, and monitor the alternator output for stable voltage and its not ranging high and low.

Aight . I have to do cpl things first I gotta poor trans fluid in, put fuse box back in, hook air intake back up, speakin of fuse box when this all first started I checked my fuses right all of em more than once couple weeks ago I stumbled upon a blown trans ign 3 fuse so I replace it but nothin happened

This situation keeps developing. 

"stumbled upon a blown trans ign 3 fuse"

If I didnt know better I would think I am on candid camera or someone is jerking my chain.  

My advice, take a mortgage on your house and find a local technician that knows this car well.  A tranny rebuild is $2800 if you need it.  

Think about us as BLIND MEN on this side of keyboard and we are dependent upon you to give us ALL information in order for us to help you.  The way this has developed in a piece meal dripping out of sequence way is not a productive use of my time or your time and it makes diagnosis near impossible.

You have a complex car there with complex problems and to google negative engine torque last night made me realize that you don't understand the way this system and I say SYSTEM, works.  

You discounted the U0101 lost communication with the transmission control module, that caused another vehicle to slip, which is your symptom, whilst having a weak battery that acts funny according to you (a bad battery can cause fits) and you just decide to throw in that you found a blown trans ign3 fuse, that might be related to the TCM!  You sent me 12 pages of codes last night friday with many failed tests and codes after saying  >>>AGAIN<<< NO P CODES on Tuesday, see photo below.  Again? 

The OBD system isn't event ready at this point to know what codes are set plus you can't drive it to do a drive cycle. See photo for an example of tests not run because the drive cycle isn't completed.  Many codes won't set without the vehicle moving like the VSS or ABS systems and you can't move the vehicle.

It is necessary to be receptive and open to ideas with something this complicated.  You have replaced parts you didn't need to replace, messed with the manual shift cable, pulled out the fuse box, and are looking to replace a pump that is an extremely advanced job for anyone without having done pressure testing with a guage.   Parts replacing is the worst thing to do, diagnostics requires a methodical thoughtful laid out process with ALL information, not a willy nilly constantly developing careless process.  You don't even have the factory service manual a must for this level of complexity.  

You drop in that your air/fuel ratio is off, with a current O2 sensor code 😀 , no kidding.  But you have no codes?, do you understand how important DTC codes are?, they are there to help you and guide you to fix the car.

You need a technician, sorry I couldn't help, i would need to be standing next to this car to help given the multitude of problems that continue to expand.  You can not filter out or hold back information you don't think is important.  

Maybe someone will chime in here that sees a way to help, this is WAY over my head and I have been working on cars since the 50s haha.  

I am waving the white flag

What I said above was not meant to be harsh in any way, nor was it to refuse to help, with 17,000 plus posts here, my primary aim is to help.

We here are dependent upon receiving accurate and timely answers to questions we ask you.    When you say "AGAIN, no p codes" , it sends our diagnosis off into the wrong direction and we waste time.    Given that your battery has been disconnected, fuses have been pulled and the battery is weak ANY CODE you extract with your code reader is suspect, that is why I said FULLY CHARGE battery.   Your situation is further complicated as the PCM can not complete a drive cycle to permit the PCM to run all tests.    A typical drive cycle is shown in the photo below.  So, you may have problems that would normally set a trouble code that can't be tested for.   

After going back and forth for days we find out, that yes, there are P codes, U0101-the TCM (transmission control module) lost communication, the ABS sensor wire is ripped out, the fuse box is ripped out, the manual shift cable is disturbed and the TRANS-IGN3 fuse that appears to be related to the TCM was blown at some point.      

DO NOT ACT on this thread, I am only posting it here for informational purposes ONLY.   But here is a person who is having Trans-IGN3 fuses blow, it was related to the TCM, so your U0101 Network code for TCM lost communication appears related to that fuse blowing.   I posted above, a link to a U0101 causing a transmission to SLIP.   Your transmission is slipping.

I would check codes again, to see if you still have a current U0101 lost communication TCM and make sure that fuse didn't blow again.

Your transmission is capable of setting the following P or powertrain codes, that is the reason we look at P codes. You will see there is even a code for slipping.

You should, fully charge battery, check the FUSE, reassemble the manual cable correctly, clear all codes, get the car on a lift again, and let the transmission run through the gears a few times and move the manual selector to each position.   Then look for all codes.

Ill get back when I can, I am working on a Holley carburetor right now and wiring a house for CAT6 and digital coax.  Ill pop back when I can. 

Stay organized.  Post facts.  I dont have a manual for your year without going to the library and using alldata.  You might check to see what your local library has for online data like Alldata.  It is VERY good.  

Maybe someone else will pop in and be able to scan the info for your year. I only have 91, 93, 94, 96 and 98.  

You really should get a factory service manual.
