abad95 Posted March 25, 2008 Report Share Posted March 25, 2008 Hi guys, Any of you guys know what this code actually is. I get the "Service Engine Soon" Message,and the tranny goes straight in 2nd as soon as you roll,and stays in 2nd. Could it be the Shift Solenoids,or the valve Body? Any input is appreciated,and Thanks in Advance... Florin Link to comment Share on other sites More sharing options...
Cadillac Jim Posted March 25, 2008 Report Share Posted March 25, 2008 P094 (E094) Transaxle Shift "A" Solenoid Problem (Vehicle Speed Sensor) My database entry is ambiguous. The VSS is NOT the transaxle shift A solenoid. What is your driveability problem? If the speedometer is acting funny and you have an occasional hard shift, it's likely the VSS. If the transmission doesn't want to move the car in low or reverse, or if the shift to second is delayed, it's the transmission solenoid. Either way, the wiring and connectors are more likely at fault than the VSS or solenoid. -- Click Here for CaddyInfo page on "How To" Read Your OBD Codes-- Click Here for my personal page to download my OBD code list as an Excel file, plus other Cadillac data -- See my CaddyInfo car blogs: 2011 CTS-V, 1997 ETC Yes, I was Jims_97_ETC before I changed cars.

fivepointohman Posted March 25, 2008 Report Share Posted March 25, 2008 I replaced my shift solenoids on my 96 SLS, and it has been mint since.. Same deal, stuck in 2nd then stuck in 1st. Its about 25 bucks in parts from GM and there re worked to be stronger than stock. Just dont forget the hold down plate that comes with the kit, As i did and ended up taking out the valve body 3 times trying to figure out what the hell was going on. The valve body replacement is easy, you can get that thing out in 20 mins. Send it! Good luck let me know if you have any questions. Link to comment Share on other sites More sharing options...

The VSS is NOT the transaxle shift A solenoid. What is your driveability problem? If the speedometer is acting funny and you have an occasional hard shift, it's likely the VSS. Since the transmission doesn't want to come out of second gear, it's the transmission solenoid. Either way, the wiring and connectors are more likely at fault than the VSS or solenoid. On the other hand, changing the solenoid is not a big deal. -- Click Here for CaddyInfo page on "How To" Read Your OBD Codes-- Click Here for my personal page to download my OBD code list as an Excel file, plus other Cadillac data -- See my CaddyInfo car blogs: 2011 CTS-V, 1997 ETC Yes, I was Jims_97_ETC before I changed cars.

fivepointohman Posted March 25, 2008 Report Share Posted March 25, 2008 Agreed with the above statement. GM ecm's are really stupid in my opinion. The solenoids are a quick change out. If you drop the pan, you can see if one of them is cracked, or pushed out sideways. Its a known issue with this tranny which is why they redesigned the solenoid in 99.

It just stays in second.It takes off in first and switches in second and then the "service engine soon" message comes on, and it drops it and keeps it in second.(Each time you start the car).Otherwise when I stop at the light and take off,It seems like It starts in second.Can't go more than 40 miles per hour(3000 RPM's). I do have reverse too,so I don't know. My brother-in-law had the same symptoms on his '95 Aurora with the same tranny,and it turned out that it was Valve Body. Thanks for your reply...

fivepointohman Posted March 25, 2008 Report Share Posted March 25, 2008 It is totally the shift solenoids..... I wouldnt worry about it, just replace them.. Link to comment Share on other sites More sharing options...
PAUL T Posted March 25, 2008 Report Share Posted March 25, 2008 I had my solenoids changed out at a local REPUTABLE tranny shop for $80.00. Dealer will want $250-350 only after they pressure you that the whole tranny needs rebuilt. It is about an hour project and is very messy. Watch out for flying springs.

You are very lucky to have a reputable tranny shop near you. Most, but not all tranny shops and dealers will try to do what your dealer did & tell you that the whole transmission needs rebuilt. I am an aircraft mechanic with Inspection Authorization privileges. I know that if it wasn't for this site, I would have thought that the transmission had lost a sprag & needed to be torn down. Instead of a couple of thousand dollars and a couple of weeks of down time, I replaced the solenoids myself for less that $100.00 including parts & fluid! I know that there are reputable transmission shops out there, but I have yet to find one. This is a great site. It has saved me many headaches and more than a few thousand dollars.

It was my understanding that they were redesigned in 96 with a bracket to stop them from cracking. I know that because I have a 96 and felt good that mine were redesigned, are you sure about your statement that they were redesigned in 99?

Here is a photo of my shift solenoids from when I did the ISS speed sensor last summer I was told by a mechanic and a dealer rep that it was redesigned in 99. The picture you have shown does not have the updated bracket. It is an " L " shaped bracket that bolts on to a exsisting valve body bolt which the kit gives you a longer bolt to replace the bolt already on the valve body. The bracket holds prefilter to the solenoids inplace where as the old prefilter does not have this bracket. Without the bracket the filter will pop out instantly causing no pressure to the valvebody.
