BodybyFisher Posted June 29, 2007 Report Share Posted June 29, 2007 One other thing. Be sure that the gasket(s)? (don't remember if it was only one or more) look fine. It's like a big sheet with some coating on both sides on it. If it peels of, then you must have a new gasket or you'll propably have an internal leak witch you don't wan't. If you're careful then this propably won't be a problem. I agree with this totally having just pulled my pump and upper control valve assembly from the side pan, the gaskets are brittle from the heat and age, and they stick and crack. You should definately have a gasket on hand that goes between the control valve and the spacer plate. Hello, please give me the part # from these gasket... Now, I thnik the most problem are the 4 balls, because I don´t know where there are... Frank Frank, let me know if you need help with the lower control valve gasket. I don't have the manual for your year, so it's difficult for me to see what you need. I can call the guys down in www.gmotors.com and see if it comes by itself. When I bought my gasket it was a three gasket set for the pump, lower control valve assembly and for between the spacer plate and the case. Let me know if you want me to call, I know the guys down there pretty good now. PM me your vin number and year that might help if you want to place an order. We can get a quote from them Friday. I have one more picture of the check ball valves for you, I will scan it and post it. By the way, you might have seen this ISS sensor thread but check out my statement regarding the gaskets again and look at the photos. Since I am only working on the car on the weekends, not having the gasket held me up a week.... Do you have the 2 lower filters and pan gasket? I am sorry you ordered from RockAuto so fast, we could have maybe saved you some money for shipping. http://caddyinfo.ipbhost.com/index.php?sho...13481&st=75 Best Wishes from the USA, Mike 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...
FSchuett Posted June 29, 2007 Author Report Share Posted June 29, 2007 Install the checkballs (5, 7, 8, 9) into the lower control valve body (903). Retain the checkballs in position with Transjel™. Hey Mike, thank you very very much for all your nice help... What do you mean with "Retain the checkballs in position with Transjel™" ? Must I reinstall the checkballs if I install the new solenoids ? What is Transjel ? With best wishes from Germany Frank Link to comment Share on other sites More sharing options...
Bruce Nunnally Posted June 29, 2007 Report Share Posted June 29, 2007 Transjel is the brand name of a grease that dissolves in transmission fluid. It can be use when rebuilding transmissions safely to hold parts such as gaskets or check balls in place until assembly is complete.

Jan Olsson Posted June 29, 2007 Report Share Posted June 29, 2007 Frank. Please don't get discouraged, this is really a simple job. When I did mine I had no experience of automatic transmissions at all. Just ordinary mechanical skill from other cars. 1) Drain the pan 2) Remove pan, filter screens (they can be reused if not clogged up, but that won't popably be a problem) 3) Disengage shifter linkage 4) Remove control valve assembly and put in on you workbench, be sure its clean and have some newspapers as protection under it 5) Split the assy in halfes, watch the balls, all 6 of them (4 metallic ones though) , be careful with the gasket. Remove shifter solenoids. Insert new ones. 6) The rest is backwards pos. 5 to 1 It always looks like "Hey I need a professional to it", but when youre working I can assure you that you'll fell like " Whas that all?" If you get stuck, let us know! Link to comment Share on other sites More sharing options...
BodybyFisher Posted June 29, 2007 Report Share Posted June 29, 2007 Yes Frank this is not a hard job at all, you don't need to uninstall all the valves shown above, I posted those photos for reference and to see the solenoids. Transgel can be replaced by vaseline, don't worry about it... This job is very easy.. Mike I will post more, another photo of the check balls and the torque specs 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...

fivepointohman Posted July 13, 2007 Report Share Posted July 13, 2007 I cannot stress enough, as i had to take off the valvebody twice, install the filter retaining rod that came in the kit, it will prevent that filter from popping out and causing the car to not shift. After that, shifts great!! Link to comment Share on other sites More sharing options...

BodybyFisher Posted July 7, 2009 Report Share Posted July 7, 2009 the lower control valve body bolts (10 of them) are torqued to 6 - 10 ft lbs, say 8 ft lbs, I would convert that to Inch Pounds and use an inch pound torque wrench, 8 foot pounds = 96 inch pounds 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...

opcow Posted September 10, 2013 Report Share Posted September 10, 2013 I'm in the middle of doing this repair (I'm waiting for the solenoid kit to arrive). I didn't see any mention of using Loctite or other thread adhesives on the 10mm bolts that hold the valve body in/together. Would it be a good/bad idea to use it?

Cadillac Jim Posted September 11, 2013 Report Share Posted September 11, 2013 I would follow the instructions in the kit to the letter regarding any and all threadlock, gasket cement, etc. -- 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.

opcow Posted September 11, 2013 Report Share Posted September 11, 2013 The instruction don't say, but I've heard it said not to use thread adhesive on internal parts unless explicitly specified, so I didn't use it. I've got some pics that may be helpful on flickr.com. I found the job to be very easy. Getting the check balls back in place is a breeze if you just do it with the upper half upside down and place the balls in their respective cups then slide the halves together.

winterset Posted September 17, 2013 Report Share Posted September 17, 2013 Congratulations on your successful diagnosis & repair! WOW - your picture showed the solenoid split apart. - did this happen on its own, or did that happen during removal? It's scary to think of these little plastic parts with coil windings controlling a transmission. - its amazing they last as long as they do.

opcow Posted September 18, 2013 Report Share Posted September 18, 2013 Yeah, the broken solenoid was the reason for the repair. Electrically, it still worked fine. The protrusion you can see sticking out from the solenoid body opposite the electrical connector is used to hold a small filter in place. This stress from this can eventually cause the solenoid to crack there. The solenoids in the replacement kit lack that protrusion. Instead, you get a metal bracket to hold the filter in place. Google "ACDelco 24211355" if you want to see what you get in the kit. Link to comment Share on other sites More sharing options...
