BodybyFisher Posted September 8, 2006 Author Report Share Posted September 8, 2006 Just wondering about any updates on your tranny sensor. My car seems to have caught that cold right now. (current topic) It has gotten worse. It used to immediately go to HISTORY and after three starts it was gone. NOW it stays CURRENT and eventually goes to history and then the light goes off. A step in the wrong direction. When it happens she drops out of OD (TCC) and my RPMs rise. I don't exceed 55 at that point. With all the rain we have had, I have not gotten a chance to look over the connection to see if its corroded or if it has tranny fluid in it. I have checked the ISS price and found prices from $27 (on line) to $65 at the dealer. I found a local rental shop that will rent me the (1,500 pound capacity) engine hoist for $75 a day or $200 for the week. I think I will have it for 2 to 3 days is my guess. It might make sense to buy it. I will also buy two more heavy duty jack stands. I plan to do my lower control arm bushings, the HVAC shroud and the heater pipes at the same time. I am hoping that I did not cause this problem. My tranny leaks badly and is usually about a quart low (at least). The sensor is in the side pan and I understand it sits in fluid. I hope that I didnt cause this by allowing the fluid to run low...

Seems like a LOT of extra work vs. using Ray's procedure in the FAQ section. When I did the Timesert job on my '97, I borrowed a hoist and engine stand from a co-worker who is also a car nut. You might ask around - maybe someone you know has a hoist. If not, I would just buy one - you will always need it longer than you think and you can always sell it after the job is done and recoup your money. My Dad's '79 Collectors' Series Town Car is leaking trans fluid like a sieve - the torque converter seal is shot. The car only has 60,000 miles on it but it is the age and inactivity that caused it to go bad. The local rental places want $30 per day to rent a transmission jack and we figured we'd need the jack for at least two days. He bought a transmission jack for $75...

BodybyFisher Posted September 8, 2006 Author Report Share Posted September 8, 2006 Oh no Kevin, I am going to drop the carriage, exactly like Ray did.. He used an engine hoist and floor jack. I will probably buy one and have it delivered, rather than worrying about carting it around, I was told I needed a truck or SUV to move it, as it would not fit in my Deville broken down. UPS ground will work just fine. I have been staring at my engine bay looking at what will need to be moved, removed and cast over my shoulder, my neighbor walked over yesterday and said, what are you looking at? Those tranny jacks make the job so much easier, it makes the job a piece of cake.. Yes, low mileage is great, but age comes into play I have come to find..

I don't expect the trans seal job to be too bad of a job. I'm sure the seal just dried up over the years due to the lack of use.

BodybyFisher Posted September 8, 2006 Author Report Share Posted September 8, 2006 The launch of Atlantis was scrubbed today due to a problem with one of the vehicle's fuel system sensors! And I should be upset that a speed sensor in my transmission is acting up after 10 years of heat, magnetic sediment and vibration?

Ed Hall Posted September 8, 2006 Report Share Posted September 8, 2006 Mike, I don't want to discourage you from fixing your car, but it sounds like a lot of work to change out the input sensor so that the torque converter will lock up. This is just an idea, but if I had this problem, I would find a way to bypass the PCM and control the lock up function with a manual switch. All that it would take would be a toggle switch and hooking up the wire to the right pin in the transmission plug. I had this setup on my diesel Suburban and had no problems with the transmission. Many people have problems with their transmission heating up while towing but mine would stay cool since I could lock up the torque converter while towing in 2nd gear up a steep grade.

Many people have problems with their transmission heating up while towing but mine would stay cool since I could lock up the torque converter while towing in 2nd gear up a steep grade. Ed, its more complicated than that. Its not just OD, there is a list of about ten items that are disabled. The PCM reads the sensor voltage that ranges from 0.5 volts at 100 RPM to more than 100 volts at 8000 RPM, in addition the ISS has a Resistance of 1300 to 1950 ohms. I will post what is affected by this code, its scary stuff... The worst?, when this code hits, the PCM commands DEFAULT Line Pressure, that is what causes the rough shifts. Also the shifts are erratic and poorly timed if you ask me. I am looking forward to doing this. My habit is to, study the job for a period of time, and do the job visually and mentally. I will accumulate the information, tools, parts and equipment I need, and do the job a month from now.. This is a challenge. Thanks for the thought however, I agree, I would have a toggle on my dash if it was simple... PS, I am selling this car also, it will be harder to sell with this code. I want it MINT, so its easy to sell and so I can get a reasonable price, I have replaced a laundry list of things, she runs great.

It seems as if you could use the floor jack on the drver's side of the cradle and leave the passenger side bolts tight. Use the floor jack to lower/support the cradle and you wouldn't need the engine hoist. Just a thought - maybe I need to read Ray's procedure.

BodybyFisher Posted September 8, 2006 Author Report Share Posted September 8, 2006 Even if I just loosen the carriage bolts on the pass side. Rays method scares me a bit as the pass bolts are out and we are effectively tilting the carriage. I think that is the reason for the engine crane, as support I will look this weekend and see how much I have to drop to clear the top of the side pan. There is a hell of a lot of stuff to detach, including the steering shaft, I guess I will get an opportinity to grease the intermediate steering shaft...

Ed Hall Posted September 8, 2006 Report Share Posted September 8, 2006 OK, Now I understand. Looks like both of us will be doing some major work on our cars at the same time. I'm planning on doing some top end work on the engine as well as rebuild the transmission. I'll describe in more detail in a new post. Just for grins, here's a picture that I took when I removed the tranny from my Allante for rebuild. See those yellow rachet tie downs. I used them to lower and raise the tranny back into the engine compartment. It actually worked very well and I was able to do the job all myself.

BodybyFisher Posted September 8, 2006 Author Report Share Posted September 8, 2006 Good thinking, there are a lot of ways to accomplish a task, huh? I have rebuild a few THM's and I can say that I enjoyed it. I think the hardest part on my job will be dropping the carriage, the sensor will be easy at that point, 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 September 27, 2006 Author Report Share Posted September 27, 2006 Ok, I am getting ready to do this job. I am a little nervous about whether or not I can do this job physically...ie, knees, back etc.. I'm not 22. Hopefully all will go fine. I found out my neighbor has an engine crane so I won't need to go for that expense.. My friend has four 6-ton jack stands which I will borrow. So it looks like I have the equipment I need. I am not thrilled about tilting the engine carriage and I would like you guys to comment on whether or not I should tilt it or just drop it straight down. I plan to remove the lower control arms, take them to my local machine shop and have the bushings replaced.. I plan to replace the axle seals and need to either borrow or buy a seal installer. I plan to replace the heater pipes and green hoses, hopefully dropping the carriage will make that job easier, with the coolant drained, its a good time to get into it. I will price the HVAC plastic housing and see how much that costs.. I am replacing the tranny filters (2), the side pan gasket and the bottom gasket. What do you think about me replacing the shift solenoids while I have the bottom pan off? I am sort of reluctant to do work in the side pan replacing the ISS (input speed sensor) and then replace the shift solenoids.. too much work at one time for someone who never did it before, in case something goes wrong, I have gone in too many directions. Any suggestions would be appreciated...

Ed Hall Posted September 27, 2006 Report Share Posted September 27, 2006 The axle seals can be installed using a large socket that's about the same diameter as the seal. That's how I installed them on the Allante transmission. One tool that made the job much easier were the rachet tie downs. I used 2 of them and was able to lower the transmission in a controlled manner. Put a piece of plywood under the transmission so that you can slide it out easier. The rachet tie downs also were also very useful in raising the transmission during installation. With the transmission suspended, it was free to move any direction and this made it a whole lot easier to get everything lined up than using a jack from underneath.

BodybyFisher Posted October 20, 2006 Author Report Share Posted October 20, 2006 Going to sit down tonight and make a list of the required parts. Hope to start this job in about a week. I get the code now on extended trips of about an hour. Otherwise I don't get the code. Called the dealer yesterday and they said they will walk me through what parts I will need, but I plan to do that myself.

clarkz71 Posted October 20, 2006 Report Share Posted October 20, 2006 Yeah, I've been putting off doing mine, not because I can't (I'm a semi-retired Mercedes tech) but because my transmission still shifts well and the TCC still works as does OD. The only changes are a slightly firmer 1-2 shift and 3-OD. 2-3 shift for some reason is the same as before. I should tell you that the shifting improved after switching to the new Dexron VI fluid. But that darn SES light drives me crazy. LOL Link to comment Share on other sites More sharing options...
BodybyFisher Posted October 20, 2006 Author Report Share Posted October 20, 2006 Thanks for the tip, I'll try the new Dextron fluid. I'll let you know how it goes.

rmac-etc Posted December 6, 2006 Report Share Posted December 6, 2006 hey bbf! Just stumbled on this thread. I have had this code for ~4 years (95 etc 156k). It would randomly shift hard (I mean Hard!!, and I posted about it at the time) but that behavior gradually stopped happening. It rarely does so now. If you haven't done the job yet, just wanted to tell you not to worry over the shift solenoids. Its intimidating but actually rather simple, esp compared to the job you are planning. You just need to know where the 4 steel balls go when you put it back together. From my experience doing that job and assuming that your newer tranny is fundamentally the same as mine, three of them are obvious, one isn't. There is a diagram somewhere that shows the locations. Oh, the reason I 'stumbled' on this thread was that I was wondering why I haven't seen Scotty around like the old days. Been busy for a while and missed some going's on.... anyway now I know! There's another mystery yet, but will keep digging before I come out and ask ... ) Link to comment Share on other sites More sharing options...

franey Posted December 7, 2006 Report Share Posted December 7, 2006 Remember when you get a hoist involved in this project if it is one of those rent a hoist, the two feet have to be extenced out under the car, which makes it real hard to place a floor jack and two bottle jacks under their with the feet.
