Code EXP 47

Recommended Posts

On startup, the DIC reads EXP 47.

A search came up empty. Can someone explain this code for me?

Thanks in advance.

The EXP codes are programmed for folks that don't speak english. A search of my owners manual shows that the code 47 equates to Change Trans Fluid. At least it does for a 1996 Seville and I assume the 1997 Seville is the same. EXP stands for export.

Thanks for the quick response. I guess we Canadians speak a different language, eh? :D

The car shifts smooth as butter .... if it ain't broke, leave it alone? Or, would you take it the dealer for a tranny fluid change?

You can change the fluid if you want to just do not let anyone to flush it.

Well, the transmission fluid is supposed to be good for over 100,000 miles but the PCM will display that message if it determines that the fluid needs to be changed, maybe from being overheated during towing, or something like that. If it is shifting fine like you said and the fluid doesn't look burnt or smell burnt then reset the DIC (I don't remeber the correct button sequence).

If the DIC says to change the trans fluid, then have the trans fluid changed....THEN reset the transaxle oil life indicator. The code is set because the trans oil life is below 10%.

Just drain the fluid and refill - don't have someone flush the trans.

Lost of information in the archives...

Do NOT Flush!

Be sure the entire trans is drained correctly, as there is

a side cover inside the trans that needs to be drained/pulled

to get out all the fluid.

The indicator is quite sophisticated and should not be ignored.

How many miles/km do you read...?

Have you towed, etc.?

I don't know about previous owner, but I've never towed and I see no hitch.

Miles are 79k

I agree with all who urge you to refresh the fluid. Either the tranny temp sensor messed up or the oil has been "hot" for some period of time.

Easy enough to do without getting under the car. You can fabricate the plumbing adapter you need to break into the cooler return line at the top LH side of the radiator. Then use the tranny pump to push all the old fluid out into a bucket.

Thanks for the advice .... I trust my oil change guy, and I'll have him drain and replace the fluid on my next change.
