BodybyFisher Posted February 23, 2020 Report Share Posted February 23, 2020 There is no need to use RTV anywhere.

BodybyFisher Posted February 23, 2020 Report Share Posted February 23, 2020 You can't do anything until you get the proper size and length all threads, nuts and an assortment of washers. Review my ISS thread and see if the size is mentioned. You need jack stands on a solid surface A come-a-long or ratcheting tie-down to pull the muffler system back Disconnect the steering shaft, one bolt about a foot from the firewall, tie the steering wheel straight ahead. It is important not to bend any suspension components, and to disconnect as needed. Personally I would disconnect both lower control arms and pull the axles. It is very difficult to give specific instructions, I sort of developed it as I went along. It is important to make sure no components are strained, AC pipes, cooler lines, heater pipes, wire harnesses, etc When I did mine, I had the crossover that houses the water pump off. Haynes is general information at best and will not be helpful for in-depth work. This is no easy job, the problem is, if you find a problem, just fixing it and putting it back together is risky, because debris, can be distributed around the tranny. Mechanical failures usually require a rebuild. You might consider buying a known good tranny from a scrap yard and putting it in.

BodybyFisher Posted February 23, 2020 Report Share Posted February 23, 2020 Look at my photos above where you see the all threads and jack stands. You support the engine/tranny carriage and remove the bolt and replace the bolts with all threads on each corner (4) with all threads and slowly let the carriage down. The left side is let down more than the right side (from the perspective of the driver). The all thread length needs to be 14 to 18 inches, Ill measure mine later Quote Pre-1995 - DTC codes OBD1 >> 1996 and newer - DTC codes OBD2 >> https://www.obd-codes.com/trouble_codes/gm/obd_codes.htm How to check for codes Caddyinfo How To Technical Archive >> http://www.caddyinfo.com/wordpress/cadillac-how-to-faq/ Cadillac History & Specifications Year by Year http://www.motorera.com/cadillac/index.htm Link to comment Share on other sites More sharing options...
BodybyFisher Posted February 23, 2020 Report Share Posted February 23, 2020 You need to determine what size your carriage bolts are, Logan's were 14mm and mine were 12mm. Remove a carriage bolt where they are doubled up and take it to lowes and home depot or whereever and match them up for size.

Logan Posted February 24, 2020 Report Share Posted February 24, 2020 The rod system works great for lowering the cradle in a controlled manner. You need rods on both L and R sides......go around and lower each nut a little bit each time.....it will lower the cradle down. 2001 Deville shown.

BodybyFisher Posted February 24, 2020 Report Share Posted February 24, 2020 I might add that @Logan developed this method of lowering the carriage. ^^^^ After you decide what size you need, you will need to order threaded rods. I am quite sure I ordered mine from MSC Direct.

Four bottle jacks, a lift where you could drop the carriage on a table, take the hood off and wrap a chain fall over a beam, floor jacks...but the bolt method isnt dangerous, it's easy, allows control, doesnt risk you pulling the car off the jack stands. You may need to free up the electrical conduit that runs along the crossover. This is potentially a highly complicated job. A few years ago I dropped the entire engine/tranny carriage on a dolly with wheels that I built (see dolly in photo below) and pulled it out from under the car, replaced the engine, and rolled it back under and lifted it back into position with the threaded rod method described above, it works.

BodybyFisher Posted February 24, 2020 Report Share Posted February 24, 2020 These are long threaded rods, you can see them in my photos and Logans photos screwed into the location where the 6 carriage bolts are. They are called THREADED RODS, I gave you a link to where to buy threaded rod above, it is called MSC DIRECT. I bought mine there. I said YOU need to determine whether you need 12MM or 14MM, no one can tell you what you need Logan above said he used 6, on in each carriage bolt hole I used 4, and only used 1 on each corner of the carriage Here is a link to a 14mm-2.0 oiled steel threaded rod in a 1 meter lengths (if that is what you need). 1 meter is about 39 inches long, and will allow you to get two 19.5 inch pieces, probably too long working on the ground, but I will give you the length I used to drop the carriage on a dolly, my guess is 16 inches long. Be sure to order bolts and washers at the same time. I would call them on the phone. You screw on the nut, cut the rod to the desired length and unscrew the nut, and the threads are restored. https://www.mscdirect.com/product/details/04355046 Quote Pre-1995 - DTC codes OBD1 >> 1996 and newer - DTC codes OBD2 >> https://www.obd-codes.com/trouble_codes/gm/obd_codes.htm How to check for codes Caddyinfo How To Technical Archive >> http://www.caddyinfo.com/wordpress/cadillac-how-to-faq/ Cadillac History & Specifications Year by Year http://www.motorera.com/cadillac/index.htm Link to comment Share on other sites More sharing options...

Cadillac Jim Posted February 24, 2020 Report Share Posted February 24, 2020 From memory from my 1997 Eldorado, the battery ground cable is double. One full-size black cable goes to the body or frame, the other goes to the engine block somewhere. This means that you don't need an engine ground strap. This is important because the starter motor and solenoid is in the "lifter valley" which is available in DOHC V8 engines, and one of three battery positive cables goes directly to the starter solenoid. This puts solid connections of both battery cables right to the starter motor. I can get my 1997 FSM from the garage if needed, but BBF has a 1996 FSM that will be identical here. NOTE: I had a good mechanic do a Northstar engine swap some years ago, and he stretched the wiring harness where it connects to the ABS and ruined the connector. He patched it and didn't tell me. Some time later it started giving trouble and it took months to find it. BBF helped me find the parts to fix the connector. A dealer found a wire pulled out of a connector and just pushed back in an fixed that to end the problem. This is a big argument to support what BBF says about being very careful about cables and wires when you drop the cradle. Another might take this incident as an argument for DIY. I had it done because I needed the car every day and didn't have time for a project.

BodybyFisher Posted February 24, 2020 Report Share Posted February 24, 2020 Hi Jim, thanks, I hope all is well. I have been reluctant to opine on specifics as this is an 06 DTS, and my 96 manual would most likely confuse the matter. Case in point neither the 96 or 97 have a TCM, so I needed to research it on Alldata at the library. I have learned to limit my responses on years I am unfamiliar with, to the point of going to the library three times searching Alldata to educate myself and to be sure information I provide is relevant or at least correct on this thread (thanks Logan 😉). There is no substitution for actual hands on experience though, of which I have none on the 06. This level of work requires a service manual Quote Pre-1995 - DTC codes OBD1 >> 1996 and newer - DTC codes OBD2 >> https://www.obd-codes.com/trouble_codes/gm/obd_codes.htm How to check for codes Caddyinfo How To Technical Archive >> http://www.caddyinfo.com/wordpress/cadillac-how-to-faq/ Cadillac History & Specifications Year by Year http://www.motorera.com/cadillac/index.htm Link to comment Share on other sites More sharing options...
Cadillac Jim Posted February 26, 2020 Report Share Posted February 26, 2020 I have the 06 DTS service manual on DVD. I believe that the question is where the battery grounds are. From the FSM, the main battery ground cable is G303, "Battery negative cable ground, under the rear seat on the right floor pan" while there is another ground cable wire, if a smaller gauge. The FSM schematic from starting circuits is attached. My IE has updated to the point that the GM SI TIFF viewer isn't there anymore. I'm trying to re-install it...OK. The smaller battery ground wire goes to the BCM, apparently as a BCM ground. It seems that there is an engine ground strap, between G110 "In the engine compartment, right side ground strap to the right frame rail below underhood - fuse block", and G111 "In the engine compartment, right side ground strap to the right frame rail below underhood - fuse block". Since they say "right side" there may be another ground strap.

Cadillac Jim Posted February 26, 2020 Report Share Posted February 26, 2020 BBF, next time you get in a tight spot and need an FSM for 2002-2012, send me a PM (I'll get an email). KingCadillac: The 4T80E has its own FSM separate from the one for the rest of the car. If you're doing significant internal work on a 4T80E, you need this manual. Anytime I take one down beyond the solenoids and such, I recommend a rebuild. That way you get seals, thrust washers, clutches, etc. and end up with essentially a new transmission. On an old transmission, anything less is really just a patch. The torque converter is not part of most rebuild kits and is purchased separately. You should change it too because the parts involving the electronically controlled torque converter clutch wear out too, and in fact that is a common failure in old 4T80Es. Note that the TCC vicious clutch "was replaced with EC3 (electronically controlled converter clutch) in 2004." (Wikipedia) If you want to cut your losses, a used 4T80E from a recycling yard is an option. Be sure and get the right one for your year. Otherwise the connectors may not match up. BBF will have more insight on that.
