90 Cadillac Brougham wont shift into 3rd gear

I have a 1990 Cadillac Brougham that has recently started giving me some problems. I have researched the web for a resolution with no luck. The other morning I was heading to work when I noticed it wouldn't shift into 3rd gear. Car goes into first gear fine, second gear fine but when time to slip into 3rd it revs up and loses power. I was told to disconnect the battery for 10 seconds to reset something BC it's digital. NO LUCK! I checked the trans fluid and was a pint low so I refilled and let it sit a while. Still wont shift into 3rd gear. HELP!!!!!!

SOURCE: E49 code on cadillac deville 1990


(Quote) I looked up code E49 and there is no such code.

The above quote is from my colleague named “txkjun”. With all due respect to him and his “Guru” status he is wrong. The code “E49” does exist, and it is an “AIR management system error".

At this time I would like to apologize for typing a word that didn’t belong in my response.

You see, when I said the code “E-49” “DOES NOT” exist I was responding to the answer that: “Txkjun” gave you.

I meant to say that the code “DOES” exist, but I simply typed in the word “NOT” by accident.

I'll get back to you with repair procedures in a few hours.

Thank You.

1990 Ford Bronco II manual transmission extremely hard to shift will not go into reverse

90 Ford Bronco II: You have to put it in whichever gear you want it in before you start it or it wont shift at all. Then once you are going its extremely hard to shift into the other gears. Reverse is the only gear that sounds like its grinding.

Don't shifts in 3rd gear on less you stop and go again

Dirty Valve Body in transaxle or internal wear

No easy fix there

The life of a taurus trans is about 65,000 avg from the
first one built thru whenever,late 90's
You can research that

I had a trans shop & caravans & taurus were 70% of the work
Just a lot of them out there I guess & when you don't change
the fluid everyone breaks down,that is 90% of any trans shop

Transmission won't shift into 3rd and 4th gear 90 toronado

If you can't fix this problem by adjusting the cable or the gear selector switch on top of the transaxle, then it's most likely an internal malfunction. You'll have to take it to a professional to have it diagnosed.
