Question about 1995 Cadillac DeVille

1996 Seville won't shift & other issues that started all at once

Rebuilt transmission 2 mths ago
Everything was fine until died while driving a few weeks ago.
Ended up replacing Fuel Pump, Fuel Filter, and Ignition module.
Battery drains overnight but tested good.
Transmission won't shift into higher gear.
Codes cleared that reappear as soon as ignition turns over are:
p0102, p0603, po753, p0758, p1645, and p1860 and RS0038

I know 102 is the MAF sensor so I replaced it with another but code still appears.

It is strange to me that all this happened at one time without it being a PCM problem and not the individual parts. That would be really coincidental, right?

    My hunch was that this problem was a short somewhere and that all these codes had something in common that could at least narrow the search down to a singular circuit. I was right. The ECS fuse circuit is for the Shift Solenoids (codes 0753, 0758, 1860) the MAF (0102), Purge Solenoid (1645). When I found that, I checked the fuse and it was blown. Replaced the fuse, reset the codes, and all is good. At least so far. There still may be an issue with a bad battery and the cause of the blown fuse is unknown and may reappear; but, at least I know which circuit to diagnose and will not be changing out parts needlessly. Sometimes, common sense prevails. I hope this helps someone else.

Dont know what exactly is the problem but all those codes are not the problem the best way is to have some tranny shop to scan it they have the chips to go inside those codes and see which one is broken , i had simular problem all the codes came up i changed parts that i did not need to change but after i found a tranny specialist i paid for my 99 sts $250 changed couple speed sensors one lose wire and done , so be careful try some other mechanic.

Intermitente starting problems & transmission seemed to go out the other day while driving it

sounds more like an engine issue off the top of my head. The transmission runs off the vacuum from the engine. If the engine timing chain is stretched it will run then not run, have problems idling and shifting and won't charge the battery properly. anyone who has done one before could probably tell you just by the sound of the engine running.

I hate to tell you but it sounds like your transmission was rebuilt incorrectly and need to be corrected or tossed and start anew, new transmissions for your truck are roughly $1,600. I'm sorry to hear about your problem.

Transmission problem

Sounds like an issue when fluid gets hot, I'd start with a filter/fluid change.

I personally shy away from tranny additives, use only as a last resort to get a vehicle drivable to trade in (on a cash for clunkers program. (((SMILE))). )

1996 Cadillac Seville started shifting hard all of a sudden

Sounds like an internal problem. To be sure you will have to drop the transmission pan and check the color o fthe fluid. It should be pink. If it is white then you are going to have to get the transmission rebuilt.

1996 Cadillac Seville started shifting hard all of a sudden

The pressure control solenoid needs to be replaced. It"s under the side cover on the transmission on drivers side. Not a simple fix at home. You will also need a side cover gasket. The transmission does not need to be rebuilt.
