"Thunking" is often a suspension issue. Possibly worn bushes, linkages or ball joints. Is it a single thunk as you first pull away or several thunks as you start to roll forwards?
The squealing brakes could be a separate issue. Ask a good mechanic to look at it and they can tell you what the problems are in more detail.
you dont need to and an 01 caddy is not a mandatory dealership for key most locksmiths dont have the equipment to cut and program automotive keys ---you have a transponder chip key some hardware and big box stores can cut new keys from an old one ---if no keys then needs to be cut by a dealer or an automotive authorized locksmith because need to cut by vin and key not $304 + also dont need to tow vehicle -----------
the word sensor , missing?
all cars in USA 1996 up for sure have CKP sensor
and 99%^ of them changed out is not cure.
not scanning the PCM first is why you miss out on causes
the crank sensor is in 3 places all
front ,middle or rear of the crank shaft.
the 3.6 L the tone wheel is on the REAR
service manual shows at #8
OP you did that all wrong.
the parts are NOT PNP
not plug and play at all and even by LAW.
those parts must be reprogrammed and remarried or IMMO will be dead.
WON'T SHIFT OUT OF 1ST IN DRIVE YOU MEANT.
IT DOES SHIFT TO PARK, NEUTRAL AND REVERES OK. RIGHT/
3.6L engine? not the bigger turbo.?6.2L
RWD OR AWD CAR?
it needs service, "obvious"?
scan the PCM yet? why skip this??? what if it shows TRANNY ERRORS max.
and check all fuses. FIRST ,SCAN SECOND.
check levels yet, on box. not guessing, do it like the book states.
check levels and tip of stick smells burnt, or looks like tar.?
or looks like metal dust in the AFT fluid there/?
shift linkage works ( per the service manual)
miles on car are? 250k miles?
check tranny pump pressure per the service manual in all gears PRNDL.
??????? at the tranny pump test ports?
6L45E TO 6L80E GM TRANSMISSION HERE
YOUR CARS VIN AND RPO LIST SHOWS WHAT BOX IS THERE, FOR SURE.
IF A SPEED SENSOR FAILS HOW CAN IT UP SHIFT, IT CAN NOT.
DO THE ON CAR TESTS IN THE SERVICE MANUAL
OR GET CAR SERVICED
54,engine bay fuse blows
only a service manual shows what all fuses connect to , in total.
only
so I read that now to you.
hummm all fuses in the SM have names not numbers.
the lid to fuse box usually has name. of the fuse.
ok only the users guide shows fuse # and 54 is clearly named
there as, POWER MODING.
AND IN FACT IS ONLY A TINY 2AMP FUSE.
THIS FUSE GOES 2 PLACES
1: IGNITION SWITCH PIN2
2: TDM THEFT DETERRENT MODULE. PIN 1.
YES GOES TO BCM PIN X1-14 , KEY ON, ONLY.
YOU WILL HAVE TO PULL MODULES, TO SEE IF MODING FUSE
HOLDS AND NOT BLOW.
I'D PULL TDM FIRST
Here's a wiring guide for the fuel pump on a 2000 Cadillac Deville:
1. Remove the fuel tank and access the fuel pump module.
2. Disconnect the electrical connector from the top of the fuel pump module.
3. Locate the wiring harness that runs from the fuel pump module to the car's electrical system.
4. Cut the wires on the old fuel pump module connector, leaving enough wire to splice the new connector onto.
5. Connect the black wire from the new fuel pump module connector to the black wire in the car's wiring harness.
6. Connect the purple wire from the new fuel pump module connector to the purple wire in the car's wiring harness.
7. Connect the gray wire from the new fuel pump module connector to the gray wire in the car's wiring harness.
8. Connect the black/white wire from the new fuel pump module connector to the black/white wire in the car's wiring harness.
9. Connect the new fuel pump module electrical connector to the car's wiring harness connector.
10. Reinstall the fuel tank.
Note that it is important to follow the wiring guide carefully to ensure proper installation and avoid damaging the fuel pump or electrical system. If you are unsure about any step of the process, it is recommended to seek assistance from a professional mechanic or refer to the vehicle's service manual.
There are two easy tests for the catalytic converters. One, use a infrared pyrometer and measure the temperature of both catalytic converters and compair the readings. There should not be much difference between the two if both are flowing correctly. Another easy test is to drill a 1/4" hole before each cat and check for excessive back pressure.
The 2007 Cadillac DTS does not have an inertia fuel reset switch. Instead, it has a fuel pump relay located in the rear fuse block under the back seat. If you are experiencing a fuel system issue, you may want to check the fuel pump relay and fuse first. If these components are functioning properly, you may need to have the fuel system diagnosed by a qualified mechanic.
the Northstar engines/4T80E transmissions there is a hidden drain plug for the transmission side cover that requires that the bottom pan be removed to drain the side cover oil storage area. The idea of flushing a 4T80E is even more ludicrous than a 4T60 transmission for this reason.

blower fan located where. dash heater blower fails
or radiator fans of some odd kind added later.
coolant fan or dash? there are 2 coolant fans and 3 relays to run them and all 3 relays, can fail and coolant fans blow for ever and ever. fuse 6 kills the relay coils. only, so if relay is welded fans blow endlessly. even if bcm is removed from the car.
on the other and the heater blower is 100% controlled by the BCM
so car engine starts and runs and drives ok right.
when did car last run perfectly> , or seen ever ?
service manuals for 88 cars are not easy to find

facts: 1988
here is proof
If your 2005 Cadillac STS is displaying "TheftLock" on the navigation and radio screen after replacing the battery, it means that the anti-theft system has been activated. Here are the steps you can take to unlock the system:
1. Turn the ignition key to the "On" position. Don't start the car, just turn the key to "On" position.
2. Wait for the "TheftLock" message to disappear from the navigation and radio screen. This may take up to 10 minutes.
3. Press and hold the "1" and "4" buttons on the radio simultaneously for several seconds until "000" appears on the screen.
4. Use the "TUNE" knob to enter the code that was provided with the vehicle's owner's manual. If you don't have the code, you will need to contact a Cadillac dealership or a certified mechanic to retrieve it for you.
5. Once you entered the correct code, press the "AM/FM" button to unlock the radio and navigation system.
If all doesn't work, it's time to contact a Cadillac dealership or a certified mechanic to help you sort it out.
Is there anything else to check before changing the motors ? Yeah , hook up a factory or some other type of professional scanner an check for DTC'S - diagnostic trouble codes,also to see if the scanner will communicate with the modules. Changing batterys without a alternate power supply can cause modules to go to sleep permanently.

Power Sunroof System Components
The Power Sunroof and Sunshade System consists of the following components:
• Sunroof control module
• Sunshade control module
• Sunroof switch
• Sunshade switch
• Rail and track assembly upon which the sunroof and sunshade glass rides
• S/ROOF/SUNSHADE Fuse 30 A
• Body control module (BCM)
Don't be a parts changer, learn how to diagnose! So before you go wasting your money on parts not needed see if a professional scanner can communicate with all the modules on the vehicle.
The Power Sunroof System will operate only with the ignition turned to the RUN or Accessory positions, this allows for retained accessory power (RAP) control of the sunroof and sunshade through the body control module (BCM). With the ignition in the run or accessory positions, the BCM supplies the sunroof and sunshade control modules with ignition voltage which allows sunroof and sunshade operation. Once the ignition switch is turned to OFF the sunroof will continue to operate until any door is opened or when the RAP timer reaches its shut-off limit. For a description and operation of the RAP operation, refer to Retained Accessory Power (RAP) Description and Operation.
Circuit/System Description
The sunroof and sunroof shade modules supply each of the switch signal circuits with a 12-volt reference. When a switch is pressed the signal circuit is pulled low signaling the sunroof or sunroof shade open or close request. The modules determine the motor direction based on inputs received from the sunroof switches. When the modules reverse the polarity of the applied voltage, the motors reverse direction. The sunroof shade module contains the logic for opening and closing the sunshade based on Serial Data from the sunroof control module. Ignition voltage is supplied to the sunroof and sunroof shade modules by the BCM. B+ is applied to the sunroof and sunroof shade modules via the S/ROOF fuse.
The sunroof shade module contains the logic for opening and closing the sunshade based on Serial Data from the sunroof control module. The sunroof shade module internally applies voltage and ground to the appropriate circuits of the reversible sunshade motor in order to move the sunshade panel to the open or closed positions.
