is this by any chance the shift solenoid C? Please i need an answer quickly im stuck on my 95 cadillac sts
It took around 5-7 hours total, if you don´t count the day in between I waited for the new solenoid to arrive. The clip for the solenoid is THE only big problem you will encounter in this job.. At least when you do it the first time. It takes patience and time but it will eventually go in. You have only around 1.5 in. room to work so flexible hands/ slim fingers are really helpful.
Thanks, I wish it would have been possible to record the actual disassembly/assembly but I only had my Iphone as camera (no tripod) and I was alone so that was the best I could do.
Can’t understand you. You need sub titles. Lol
P1577 is BBV Sensor Circ Lo Voltage / Brake Boost Vacuum Sensor
P1860 is TCC PWM Solenoid Circ Electrical, which relates to the torque converter but should not interfere with reverse gear.
Those codes should not have anything in common with a no reverse condition. Any other codes?
Best regards

hello eaglevision993 i am from saudia arabia .i have 2000 cadillac dts which not go to reverse but it run forward very good when i check it with scanner it give code po1860 po 1577 ,please help me love from arabia
Uh… Yeeahh.. 🙂 Great video.
Other than CV axles I could only imagine a bearing making that noise. How are your wheel bearings? Very ahrd to guess without hearing it. But if it is more of a groaning noise I would say wheel bearing if it changes with speed. If it changes with speed it must be on the output side of the transmission. If it chnages with RPMs then on the engine/input side. Did you ask in the CadillacForums? Best regards
could use your expertise plse.!…2001 Cadillac sts Seville ..thought my roaring noise was coming from my cv axles ..replaced them both ..no such luck .noise starts at about 20 mph ..and gets worse ..the noise sounds like its coming from the center of the trans at the bottom of the pan .would a bad tcc make this noise ?
ya i do have same codes. and hes right is has to be the tcc solenoid, and the next is the circuit solenoid which is in the bottom. the second 1 is easy when you do the trans. oil u can see it there.
wonder how many hours toke you to removed all the parts. and to remove the clip that comes with tcc solenoid how did you do that.
If I remember it right, I supported the transmission at the transmission pan. I placed a piece of wood on a jack and just put enough pressure on the jack to firmly secure the trans. Not too tight! The wood should be big enough to reach at least 2 edges of the trans pan.
Just about to tackle the TCC solenoid, thanks to your video. Before removing the motor mount, where exactly did you support the transmission? Please
Hey blackshit. Did yu get it fixed. Looks very do-able
thanks appreciate it ima have replace soon I got some to do for 600 just wanted to make sure before I paid
Under normal conditions with the engine at operating temperature the transmission shifts 1st, 2nd, 3rd, 4th (overdrive). Additionally, it can lock up the torque converter to minimize slip. This may feel like an additional shift as the RPMs drop another 2-300 when the torque converter clutch engages, aka “locks up”. If you have both codes, chances are high you have the same problem as I had, a bad TCC switch. For the other lights, you have to check the codes to find the sources.
yea I have both codes and wat you mean buy locking up you mean wen trany shifts I notice a lil more jerk at times but just a lil but at times it shifts smooth I also have the service stability sustem abs and traction light that come on at times 2
The method shown is in no shop manual or such, it is a unique method used by DIY repair guys. Check the Cadillac Forums.com to see if other Deville owners did it. I bet they did.
The 4t80e is the exact same transmission. Only the space around the trans matters. You may have a look yourself. If the space between the frame/fender and the side cover is around an inch or so I´d say it is the same. There is not much space, 1-2 inches at most iirc.
That is the EXACT model year and transmission/ powertrain on which this video was shot. I doubt that the Deville, which should have more space around the engine as it is a bigger car, would be different.
Regular shops will most likely not do it this way. Dropping the cradle will get them way more money. Cheating shops may tell you ” Uh it was a hell of a job with dropping the engine and such…” while doing it the easy way. Only use a shop with good reputation if you have to.
just called my transmission shop to have this done and they said they cant do it on the 4t80e (2000 deville) does that sound right??
Let us know how it went! And remember, take your time when you remove and reinstall the solenoid. It is somewhat tricky as the view is very restricted. If you encounter any problems you may send me mail anytime.
I am in the middle of this now, eaglevision..Thanks for the video…i have one bolt on the tranny cover to remove before I get in. Hoping to finish tonight!
If I remember correctly, one of the bolt does not need to get all the way out. You remove the nut on the stud that holds the bracket. Behind it is another nut holding the transmission case. Just loosen this bolt until the case has enough room to swing open. The transmission case will not come all the way out.
How did you do it piecefarm?
I am having the same issue not being able to get that mount bracket out. I see that you dont actually need to take it completly out but how do you then get the bolt/nut out in order to take the transaxle case out.
Do you only have the P1860 or also the P0741 code? Both together are 99% the solenoid itself. It is normal for the code to reset after some time. The car tries to lock up a number of times before it sets the code and it depends on how fast and constant you drive how often the lockup is actually requested.
Did you lose the lockup at all times ot does it work after you reset the codes?
i have the p1860 code so i know it somthing to do wit the tcc solenoid but when i reset the codes it dont come on till like a few hours later so could it be the wire going to the tcc splenoid
Glad I could help. As for the job, yeah a magnet and lots of patience are the most essential tools.
Thanks to eaglevision993 and both videos, I was able to replace my tcc solenoid in my 2001 Cadillac Deville DHS. I could not have done it without this video and the personal emails and tips from eaglevision993. It is possible to change it out but it is a test of patience. Reinserting the little U shaped clip is the most difficult part of the entire procedure. GET A MAGNET and tie a string to the clip if you attempt to do this. It works!
It won’t let me send you a photo. My email is drbenpierce@yahoo.com the bottom two bolts on the bracket came off but the one you can’t remove only back out is the one i am having issues with
I will send you a PM with my mail!
Do I need to jack up the transmission to back out that bolt? If you send me your email i will send you a picture for clarification. I have a few more questions if you don’t mind. Thanks again.
Thanks for the reply. It’s the one that will not come out that i am talking about. It has a nut between the frame and the arm of the motor mount then it is a threaded bolt with another nut against the side plate. I will figure out the size but its bigger than 18 mm. The main issue for me is backing it out with almost no space to work with. I can only access it from underneath because it is so tight a space.
The bracket you see at 3:50 is the one that will not come out. The lower 2 bolts will come out, the upper one will not. It can only be loosened because of clearance issues. The nut on the trans mount itself, going through the frame sideways may have been a 18mm nut but I really can´t tell you for sure.
Or do you mean the bolt that goes through the frame and holds the mount to the frame itself? The one with the locking tab?
