I've never liked anything but factory service manuals. I would bet a Haynes will say 'Transmission service is beyond the scope of this manual. See an experienced service person for this area.'
Look on ebay for a set (2 books) of service manuals. Probably should go for about $50. A new set can be bought at www.helmsinc.com . Factory manuals will cover tranny dis-assembly.
P.S. It's a Cadillac. You could spend LOTS of money on it!
P.P.S. If you don't know the service history on the car, I would change the coolant. Look at the belts, there is a small one that drives the water pump off the rear of the left cam.

Well I went and took a look at it yesterday and I didn't like what I seen. I have been working on cars for about 12 years and if I have to take the tranny apart in the engine compartment, I ain't gettin it. Other besides that the car was in great shape and it had 154000mi in it. New water pump and belt. Thanks for the input on this car. I think that I am going to stick with my Neon. Thank you Bolivar.

I have a 96 deville.One of the sensors inside the trans is messin up... It has been diagnosed as the speed input sensor.I was checking this sight to see if anyone else had sim prob...Some I read was from 2006....sooooooo. I need to replace it. I also know there are 2 diff in trans,, I plan to do both,,, tokeep from haveing to repeat a expensive repair. I hope not to mess with the rest of the trans. Car has over 165,000,,,All else seems to work well...Does anyone have experence with this repair? and have advise..rebeccat

Well, I think this is the dreaded '$40 part buried $2,000 deep in the transmission'. The error code is something like a 720 or 721 or something like this.
The transmission (and ususally they pull the motor and tranny together) has to be pulled to get to this solonid. This solonid locks up the torque converter. So, the car usually can be driven, your milage will just suffer because it is not locking the converter up after 45mph or so.
The other two solonids, shift solonids, known at the A and B solonids, are easier to get to and do not require the removal of the tranny. And yes, if you do go into the tranny to get the VSS/speed sensor one, you should also replace the A and B shift ones.
#2363 of 2635 Need Expert Advice on Comparing 2000 Deville and Eldorado
Aug 20, 2007 (9:16 am)
Looking for some sage advice from experienced Cadillac type. Decided to buy a used Cadillac, wanted a Northstar engine. Decided on 2000 because they made improvements to the motor. Regular gas, redesign etc. Assuming it makes sense to get 2000 vs. earlier due to motor advances?
Can get equally good deal on a Deville DTC or Eldorado ETC. I prefer the classic body style of the Eldorado and would have to get use to the look of the new style Deville. Like the taillights on the Deville but the front end is different. Also, age 46, only me and the wife and a small dog, no kids.
Is it just a question of looks and desired style or is the redesigned body on the Deville model for 2000 significant enough that I would notice the difference in quality, ride, or performance?
Bottom line is I could learn to like the looks of the Deville body style if the drive experience was significantly different over the traditional chassis on the Eldorado. I prefer the looks of the Eldorado but do not want to give up too much for that style preference. Hence lies the dilemma.
Thanks in Advance.

Hey, you are asking questions that only your personal preference can answer.
Go test drive both and decide.
One thing about 2000 model Northstar - Crank sensors. There are two of them. And many of them fail. Failure will cause a total engine stop, and it could be at speed. If your car does just die suddenly, this is probably the problem, and I would repair it quickly before you have a flameout at 75mph in the left lane of a busy highway.

Thanks, sounds like what I have heard so far. But the dealer and the independent shop hasn't mentioned pulling the engine too. Hope not, sounds like a way to start a never ending chain of failures. Can't pay that bill!
Curious question.. The other guy that was talking about a 2000 ,,, you said something about it cutting off with him...Does my 96 have the same thing that can do that??? Because it has been (as you say..Flamed out!) At different times. mostly while slowing or accelerating, BUT.. has done it sitting still in driveway?? Thought it could be a lose wire( had a turn signal module fixed not long before it started).... or thought maybe the Computor...So am I on the wrong track there? thanks rebeccat

Well, from what I've read, the 2000 and maybe up into the 2001 models seemed to have an especially bad batch of crank sensors, with lots of failures.
But, I am pretty sure earlier models of Northstars also had 2 crank sensors. 1995 and earlier had a totally different 'computer' system (ODBC I), and I'm not sure about these.
Your 1996 is an ODBC II, and probably has 2.
If a Northstar just 'drops dead', a crank sensor problem would be the first thing I would consider. Especially if NO error code was set. It seems these things shut stuff down so fast, it does not even get to set an error code.
They are not especially expensive, and not too much problem to reach. They are both just above the oil filter adapter. I think oil needs drained, filter and adapter removed, and there they are.
