2nd Update oct 22nd 7:30p.m.
Conditions up to this point...
Car in limp home mode, 2nd gear (I stand corrected! It just seems like 1st !)
No Speedometer, odometer, cruise control function.
All lights on transmission are lit up on the indicator are green, except for reverse which is red.
Check engine light is on.
Replaced both speed sensors, mostly because of minimum rack time, OBDI II indication of input sensor, speedometer not working, relative cost of the sensors, and that every Shuck's has them in stock and sell a bunch of them, the need of balanced voltage between input and output speed sensors (some say that they can become imbalanced with metal filings if the trans is giving off shavings & some say that they need to be cleaned when you change fluid- I say just cheap insurance)
Took the car to a transmission shop and had the cars engine, body and transmission computers scanned. Transmission computer was not communicating.
Checked voltage between the standing battery voltage and the input to every input voltage to the fuse block and found them at a maximum of less than .4 volts .
Followed the shops recommendations and tried to buy a TCM yesterday, but they didn't have one.
ACCORDING TO WHAT I HAVE FOUND-
A 1996 Intrepid Is a one year TCM and there are 2 of them in this year, one is Autostick (which mine is not !)
A mini van, K car, diesel pickup or what ever won't work-
1996 New Yorker
with a 3.5 are the ONLY replacements for this TCM.
Went to the local Pull and Save and purchased these parts.
Washer pump with sensor and wiring harness, Ash tray w/ receiver and 3 lighters, like new Goodyear Gator serpentine belt, all fuses and relays in the passenger and engine compartment, new battery cables, ignition switch w/ connector, owners manual, cup holders in the arm rests and the CORRECT TCM.
Total cost $20.85
After about a hour and a half there I was beat. Went down the road a little and realized that the TCM did not have a ground thru the body mounts, Gained the energy and pulled in to the the local grocery store and pulled the connector off and installed the new TCM......
And SUCCESS !!!!
The transmission indicator only indicated the gear that I was in!!! The check engine indicator light was still on- but I had all gears!!!
Drove it to Shuck's and cleared the codes and drove it and the lights were still off!! No engine, body, or transmission codes!!! Drove it up the highway @ 70- shifted like a dream....
As for throwing parts at it.
It was indicating an input speed sensor Suffix "a". Logic tells me that when EVERY Shuck's in town stocks both of them, logic tells me the cost is there, and logic tells me the install is the same- Logic tells me to do it, and if not I am still some what of a gambler... total gain was I eliminated the under car sensor problems and and gained 3 friends at that shop. They also gave me sound advise and told me to install a used TCM from Spalding's.
Confidence shaken, logic told me to take it to a place that had the latest diagnostic tools and they gave me their best guess at wiring or TCM
Yes, I have a library card and I use it- they have the same source as Auto Zoner. I also looked at other forums and data bases. For other people that are not as lucky as I, the next step is to reground the wiring harness and clean the connector to the computers.
Logic tells me to approach people that know more that me or have had the same experience that I am having.
The connection between the ignition switch and the operation of the window regulator is that it took me about three times to encounter the failure of the window operation to figure out that 1) the ignition switch might have been bad, not providing enough voltage to operate the lift motor, and therefore might be the root problem of my transmission problems 2) the lift motor might be going out, 3) the switch or body wiring may be bad.... Ultimately it is probably a bad window regulator- which is just by my previous MN 12 Ford experience... window regulator or transmission is bad and it pushes out the arm rest... Just a product of knowing the symptoms, just what I was asking for in this forum...
