tomcad95 Posted September 10, 2009 Report Share Posted September 10, 2009 A couple of weeks ago I had my tranny fluid and filter changed on my 95 Deville 4.9. Yesterday when I checked the level of the fluid it was way over the full mark on the dip stick. I went back to the shop and they told me there is a Service Bulletin for that tranny and it is supposed to get more fluid then originally specified. I don't remember what the tranny number was that he rambled off. Has anyone heard of this Service Bulletin? Link to comment Share on other sites More sharing options...

adallak Posted September 10, 2009 Report Share Posted September 10, 2009 BS. Run the engine until it reaches 180-190 F. Siphon out the excess as BBF suggested. I would not bother to go to the stealer, but if you do, ask them to show the "service bulletin".

BodybyFisher Posted September 10, 2009 Report Share Posted September 10, 2009 Look at this article, see the statement on overfill and the bottom colored area http://www.aa1car.com/library/atf.htm You are looking for these statements If the fluid is full of bubbles or is foamy, the transmission is probably overfilled with ATF. It is important to remember to NEVER over-fill the transmission assembly and to ALWAYS use the recommended transmission fluid. To discourage over-filling, some vehicle manufacturers have eliminated the dipstick on the transmission. Unfortunately, this also makes it hard to tell if the fluid level is low 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...
winterset Posted September 10, 2009 Report Share Posted September 10, 2009 tomcad - I am curious if this is th first time you had your fluid changed. I have my '96, and I naver had it changed now @ 105000. the owners manual said lifetime fluid, but I am hearing 10years or 100k now. Undecided if I am up to doing it myself, and I know not to get a flush, and I kinda don't want to disturb the pan & filter. I was going to have a shop disconnect it at the radiator & fush it out in park that way. Link to comment Share on other sites More sharing options...
Ranger Posted September 11, 2009 Report Share Posted September 11, 2009 I don't remember what the tranny number was that he rambled off. You have a 4T60E. Winterset, If you don't go by the "lifetime" in the manual (I don't). 100K is about right. You would be better off doing both. Drop the pan. There is a magnet in there that is full of metallic muck from the clutches that needs to be cleaned. No filters to change in yours (4T80E), just reusable screens. Filters are buried deep in the trans and only get changed with a tear down. THEN have them pull the line and pump thge remainder out of the TC.

joeb Posted September 11, 2009 Report Share Posted September 11, 2009 i tried to use a small pump to suck out some trans fluid. won't work on the 4t80e. there is a metallic object in bottom of fill port. i always have been able to get at least 1 gallon from every other car i have owned. i replace 1 gallon at least once a year on my cars in additon to dropping the pans and filter changes. i am always surprised at the dull, opaque color of used tranny fluid.

I understood if you disconnect (I forget top or bottom tranny cooler line from the radiator), and keep the car in park, start it up, and it wll blow the fluid out of the line. I know you should NEVER put the car in drive while doing this, as something will get "crushed" internally. I plan to: 1) pump the tranny fluid out the radiator cooler 2) drop the pan & clean the magnet, pan & screen 3) I believe we have to always replace the gasket, but there is only one kind that works Sorry I need to research this by searching the forum for details.

Joe, I made a 3/8" adaptor, that I attach to the upper cooler line on the radiator, and I put a hose on it, and direct it into a 5 gallon bucket and pump it out in PARK, once it spits, I stop the engine immediately, then refill.

I change my fluid every couple of years this was I have a photo of my adaptor, Ill find it in my photobucket I second this method because I've done it this way a number of times. This method was originally suggested by the Guru. As the Guru said, as long as it's kept in park all should be fine. Of course don't run the engine beyond the point where the fluid is drained--there's no reason for it and why take a chance. Home Depot and/or Ace Hardware will have the right adapter along with clear plastic tubing. It's an inexpensive setup. Now that I have the '05 STS I have to see if I can drain the trans fluid through cooler lines. Link to comment Share on other sites More sharing options...
joeb Posted September 12, 2009 Report Share Posted September 12, 2009 i just pumped out my grand prix this week. got 5 quarts. makes me feel better. most stores sell trans fluid in gallon jugs. the caddy gasket is a metal/rubber sandwich. it is reusable if you don't beat on it. i stick the pump suction line down the fill tube and am done in minutes. pretty easy and mess free.

JimD Posted September 12, 2009 Report Share Posted September 12, 2009 This is the fitting I use. One caveat; my transmission plumbing uses quick-release fittings on the OEM plumbing and it is necessary for me to remove the adapter from the transmission cooler to install my brass adapter fitting. Still an easy and clean job. No transmission fluid dripping off your elbows. Jim Drive your car. Use your cell phone. CHOOSE ONE ! Link to comment Share on other sites More sharing options...
winterset Posted September 12, 2009 Report Share Posted September 12, 2009 so just to be clear. if drop the pan (first time ever removed). I do not need to replace the gasket. I'll just clean everything up (screens,pan,gasket) & put everything back. Is this how everyone does it? I am just concerned about the age of the gasket.

At that mileage and age, I would change it. winter, if you PM me your address, I will send you a new pan gasket, I have one hanging in my garage in the package, Ill mail it to you. Change the two filters however and any seals that are used in their attachment to the tranny.

Ranger Posted September 13, 2009 Report Share Posted September 13, 2009 Wait a minute Mike. There are no accessible filters. Are you talking about the reusable screens? They just get rinsed (if that) and reused. Mine (on my '97 at 100K) where clean. I'll just clean everything up (screens,pan,gasket) & put everything back. Is this how everyone does it? That is the least I would do. Add Jim & Mikes method of pumping out the TC to get the remainder of the fluid out if you want to. That would be the best of both worlds.

JimD Posted September 13, 2009 Report Share Posted September 13, 2009 Personal opinion follows! I would walk barefoot on whitehot coals rather than open the bottom of a transmission case for the purpose of a simple fluid change. Whatever metallic and other crud that has settled at the lowest point will NOT be recirculated throughout the transmission valves and seals. Jim Drive your car. Use your cell phone. CHOOSE ONE !
