milansky Posted April 25, 2018 Author Report Share Posted April 25, 2018 Here is update on 1996 Seville stuck in second gear: If your transmission is stuck in second gear make sure that O-ring on small screen/filter in between 2 shift solenoids in lower valve body holds that small screen in place all the way in. After transmission overhaul car was suffering in second gear only conditions over and over. No codes present. All solenoids replaced including screens and main filter. Will post a picture of what Im talking about after figuring out how to get a photo in here. Link to comment Share on other sites More sharing options...

Did it have to do with the bracket? @milansky 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...

Did it have to do with the bracket? @milansky No. Bracket intended for solenoids were not the case. There are small click-on pins that hold solenoids in place. It was all about that small screen and probably small original Oring on screen that simple popped out. We drilled very small and short hole (about 2milimiters) for miniature screw to hold it in. The screen im talking about. Link to comment Share on other sites More sharing options...
BodybyFisher Posted April 26, 2018 Report Share Posted April 26, 2018 @milansky maybe I wasn't clear. I know you are speaking about the screen. It was unclear why the screen kept popping out. It seems odd that you needed to devise a system to hold it in.

Have u ever assisted anyone on this forum with rough idle after engine start problem during cold weather? I get P 0101code awhile after start when engine shakes as crazy but it disappears as soon as engine warms up and rough idle settles. No other codes or vacuum leaks. No fuel related leaks. If IAC valve is responsible for proper air+fuel mixture during cold start with air temperatures around 32 up to 60F, could that be a problem?

BodybyFisher Posted April 30, 2018 Report Share Posted April 30, 2018 In the manual on P0101 under intermittant code have you seen this? Have you looked at possible causes? I will look into the snapshot and see if we can retrieve the data 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...
milansky Posted April 30, 2018 Author Report Share Posted April 30, 2018 Yes that was checked. It's gotta be something that deals with temperature monitoring and mixing wrong air with fuel when it is called outside. As soon as engine warms up all goes back to normal. No oxygen sensor codes either. Im wondering whether faulty ECT sensor could be responsible for it. Link to comment Share on other sites More sharing options...
BodybyFisher Posted April 30, 2018 Report Share Posted April 30, 2018 It is very easy to figure out but you must retrieve the snapshot data to know what set it. When the P0101 sets it saves a snap shot of what went wrong. By comparing that data to norms you will see what set it. Do you have access to a tech2? I will look later to see if there is a way to access the snapshot data through the dash.

But, in reality, I learn from you, while trying to help you, so we both benefit here. Thanks See this thread. I know that prior to 96, snapshots could be retrieved through the dash, I am not sure that is true after 95. When your P0101 sets, it stores a snapshot to be able to see what went wrong, it should be stored in your PCM as long as the battery hasn't been disconnected. I will continue to research this. The fellow in this thread has a 2000, and he got a message that a snapshot was taken.

BodybyFisher Posted May 4, 2018 Report Share Posted May 4, 2018 This is good also, it shows clearly how the strainer/filter popping out blocks fluid flow. Thank you.
