My 1996 cadillac eldorado has shifting problem

Hello,my name is john and I am having a problem with my 96' eldorado shifting gears. When the car gets up to about 40 mph it seems to just drop out of gear,but if I press on the accelerator only the rpms jump up but the car does not move any faster. As soon as I let the car fall back down below 40 mph the gear comes back.I use my car for work all over and I hope that someone out there can help me with my problem. Thanks.

Wow. I am having the exact trouble with my 1996 Sedan Deville. Did you have any luck figuring out what the problem was? I have taken my vehicle to a transmission specialist and was told to have the electrical system checked? As a matter of the fact, now it's not changing gears at all. It seems to be stuck in 2nd gear even with acceleration being applied? Can anyone help answer this question?

It's the shift solenoids.. Chances are one is broken off.. I had the same problem and got TONS of help from the fellas on this board for it.. Suprisingly, it's a HUGE piece of cake to repair. seriously.. you can do the entire job for less than $100 which includes parts, a case of trans fluid ( only needed 6 quarts for mine), a bag of clean shop rags, BIG oil catch pan and whatever else you'll need. I can give you a complete step by step on this if you'd like. It sure as hell beats having the dealer tell you it takes 7 hours to do and charge you $500 to do it.. That's what Crest Cadillac's service department says the job costs. I guess when you're the ONLY cadillac dealership in the Syracuse NY area, you can rape people like that I suppose. I went back later and asked them what kind of crap a$$ mechanics they have there that takes them 7 hours to remove the trans pan and valve body. I've never even OWNED a cadillac before and I did the job using nothing but hand tools in 2.75 hours.

Anyways.. Don't be alarmed. Your car defaults to 2nd gear and stays there. It's like a "safe-mode" so you don't break anything else. If you drive around town, then worry not.. you can wait till a weekend to do this repair.. If you have to drive on the highway, then you're gonna want to do this quickly.

If you decide to do this, you can first verify this problem by simply removing the trans oil pan. You will see 2 electric solenoids side by side. one will either look bent, cracked, etc or completely broken off. you'll see it hanging. That would be your first and cheapest step.. but if you're going to do that, you may as well spend the $50 and go get the service kit from Cadillac. I can give you the part number if you want it. as long as you don't open it, you can take it back if it's not the case. Anyways.. reply to this if you'd like a detailed explaination on the solenoid issue and how to fix it. maybe I'll see about making a sticky..

I Just Saw Your Post On The Shift Problem. My 93 300 Hp Eldo Did The Same Thing 3 Days Ago. I Believe The Broken Solenoid May Be The Problem. I Also Saw Another Post That Mentioned A Kit For The Older 4t80e S But I Can't Find It Now Do You Know What It Was ?

Re: My 1996 cadillac eldorado has shifting problem

Depending on what codes the car is throwing, its probably the shift solenoids. I had the exact same problem in my car..and it was throwing the code for the input speed sensor. Got that replaced for $700 then it started throwing the shift solenoid codes. I got them replaced for $320 and now the car is running great. So, post what error codes are being put out and hopefully its your shift solenoid!

Just a late follow-up. It was the 1-2 shift solenoid broken. The factory kit includes a new filter, a retainer for it, and both solenoids. A note enclosed states that all 4T80 E's built before 12/96 should have this kit installed. I paid $48. for the kit, reused the old gasket and 8 qts fluid. It took me about five hours but I'm slow as hell.
Thanks for the help. It's great to find people who know what they're talking about. It's becoming a rare ocasion.
