Cadillac Repair/Transmission


Hi I was wondering how hard it is to remove and install a 1992 Cadillac Deville Transmission. It is the 4t60-E transmission. I had replaced the radiator and the transmission cooler broke and contaminated the transmission fluid. So I was told a new transmission would be needed. I am most likely going to pull a used one because I am not looking for something long term since it rarely gets driven. I am wondering what you have to do to install it and remove it. I was told you have to lift the engine and then remove the subframe to get the transmisson out. Thanks for any advice.

Well, since there is nothing to lose here other than the flush, I would suggest getting the car towed to a place capable of flushing the transmission fluid and see if that will fix you up.
This car is far too old to put a new transmission in.
Your question about replacement is very wise since it appears that you have never partaken on this type of adventure and you ask questions first.
Since I am not at the vehicle to access the damage to the transmission from coolant, I will only offer another suggestion on the flush. Instead of replacing with Dexron III consider installing Ford type F fluid. Ford fluid causes the transmission clutches to grip better in this type of situation. This is not a guaranteed fix, but if you could get extra mileage out of the transmission, why not try it?
I attempt to assist people to save money and repair their own vehicles. In this case however it appears that you are not familiar with what is entailed. What you were told about the cradle is correct. The front suspension has to come apart and more. A very labor intensive job. Not only that, but you need the brace to support the engine. This is a massive job for a novice without the required equipment and tools. That is why I suggest trying to see if a transmission fluid flush works. Its not an everyday car.
If you end up with a used trans, many junk yards do installation. Call around as well as transmission rebuilders.
Now, if you go the flush route first, keep in mind that the cost for fluid will not be cheap because the lines, the trans and the converter will need replacement fluid which could be higher than 15 quarts.
The use of Ford fluid we have used as a bandaid in situations like this and when the trans was slipping and by no means is recommended, but it worked for us in a situation like yours and it totally depends on how much coolant residue will be left on the clutches.
Let me know what you end up doing.
Good Luck!

Good luck!


On occasion, I address our business and what we have to offer insureds. Such is one of these occasions, and unfortunately people just assume if their car is stolen, the carrier will expedite the process and honor the claim. Unfortunately, this has not been true for a very long time. If a vehicle is stolen, and the claim goes to the SIU (Special Investigation Unit)chances are 99 out of a hundred that the ultimate goal is to link the insured to the theft, for the purpose of denying the claim. In criminal investigations, one is given Miranda rights, where everything said can be held against the suspect. In civil investigations, the difference is that they are not required to give Miranda rights, although everything you say to your insurance company can and will be held against you.
No one ever considers the fact that if their vehicle is stolen, not only will they not be paid, but have their name tarnished for life.  (many plaintiff attorneys are not even aware of this)
In fact, we are even considering offering defense insurance against insurers similar to an extended warranty if you will.

We are the leaders even over many attorneys assisting our clients through the SIU investigation process in reported stolen vehicle claims. Many attorneys will state that auto theft claims investigation and denial are the first case of its type they have been involved in. In contrast, we have worked with, trained with the SIUs for over 20 years as it relates to auto theft claims and how the vehicle was last driven. The courts have been hoodwinked by the carrier's use of certified forensic locksmiths, forensic examiners, mechanics and engineers qualifying as experts capable of determining what methods of theft a thief would use. We know all the national insurance "forensic" experts out there as well as knowing the difference between blatant speculation they testify to as fact, in which they will state that the reported stolen vehicle, even if totally destroyed by fire or never recovered was last driven with a key of the proper type or correct key.
One needs t understand, the insurance company has no intention of paying a theft claim. They cannot just deny a claim. They need what they refer to as an "independent" source operating under a  self-appointed title of "forensic" to give credence to their opinions. Once a report is written inferring the insured was involved with the theft of their car, this gives the investigator the green light to manufacture a financial motive. These investigations are a house of cards and we are more than capable of taking the expert out, by causing him to self impeach with our system. Once the expert's conclusions are deemed irrelevant, the question then is; If you can't determine if the vehicle was stolen or if a fraud, the only recourse is for the carrier to honor the claim.
I have served as an expert witness across the nation for 17 years, qualifying in 18 states as well as federal court numerous times in both civil and criminal arenas. I know the other side's defense and how to attack it successfully before it becomes an issue.
We offer insured's exciting controversial non -conventional approaches to these situations.
I have retired after 17 long years of being a rebuttal expert witness after 17 years of un-based personal and professional attacks by unethical opposing insurance defense teams. One knows they are desperate when I am in a deposition being asked about my personal romantic life, where my ex-wife is located and if I blame a carrier for my divorce. Or a subpoena trying to link me to the business ownership, full inventory including cost of our tools and equipment or my military discharge papers from over 40 years ago in which I was released under honorable conditions. All this and more as it relates to stolen car claims. One knows I am to be feared when the time and expense was employed after 16 years to compile a book on me to be unsuccessfully used by opposing defense attorneys, and strangely, I am the only one in the field that has such a book compiled on them.
Services now offered--We have expert witnesses trained by me if the situation so demands .

We offer non-disclosed consulting to attorneys in order to supply them with the much needed information to cause these experts to self-impeach their own testimony either in deposition or during cross examination.

One additional service we have been offering for about 3 years with a great amount of success is representing clients under Power of Attorney, which gives us many of the same rights as lawyers are afforded, because we are not arguing the law which can be a detriment in these cases, but we supply fact. We advise our clients every step of the way as to how to truthfully answering the questions, without having to defend one's self. We prepare our clients for investigation interviews as well as for the dreaded examination under oath (EUO).

The only answer you as the insured needs to consider when asking themselves if they should get an attorney for the investigation if they are not guilty of what they are being accused of. Do I want an attorney, no matter how good they are in personal injury, malpractice etc.that has never defended an auto theft case, or do I want someone that has exclusively defended these claims and cases for two decades?

Alarm system questions cannot be answered on this forum. These systems are not what I can answer. Without being physically at the vehicle and not knowing what kind of electrical service has been done on the vehicle, there is no possible way to give an accurate answer over the internet. My expertise is in Ignition/key based anti-theft systems. These issues include GM VATS (resistor chip in key blade) PASSLOCK (MRD)-ignition lock rotation based, no special ignition key and the PKIII Transponder (computer chip in key) systems. These systems are not alarm based and are integral with the starting of the engine. This is why I cannot diagnose alarm problems without physically looking at the vehicle: Alarm systems are a completely different annimal than ignition key/lock based anti-theft system. Many alarm questions come from vehicles 10 years old, and since older, many hands that had been involved over the years.I am an expert in all GM factory (ignition/key based)systems. Alarm system questions pose to many situations beyond my knowledge as to what has been done to the vehicle over the years. Some guy may have actually wired the stereo into the alarm system. Who knows? Over my past 30 years in vehicle wiring repair, I have seen unbelievable wiring disaters done by guys that consider themselves "mechanics." I have seen stereos and alarms intalled using surgical tape. I have seen modules burn up, un-fused circuits, wiring jambed between the doors and even lamp cord used for a starter kill. To answer alarm questions over the internet without examining the vehicle is like asking; What does it take to remove a dent?
