98 Intrepid won't shift

My wifes 98 Intrepid just started acting crazy, it shifts from first to
second almost instantly but won't go higher. The speedometer stays at 0,
it dies at stops, and the check engine light stays on. Can anyone tell
me what's up?
Thanks in advance
Tim

 

You need to replace the output speed sensor on the tranny. It's in
what's called "limp" or "limp home" mode be because the sensor is not
working - doesn't allow tranny to shift out of 2nd gear (just like the
'Friends' TV show song). Cost of part is $20-40 depending on dealer.
Takes about 15 to 20 minutes to replace for a first-time DIY'er, or pay
a dealer $70-$100.

So, since the check engine light is on, what codes are stored in the
computer?

 

Your transmission output speed sensor is probably toast. Easy fix.

 

The only code I get is P1864 I have had the battery out so that makes
sence. My manual (Chilton) dosn't mention an output speed control
sensor, can you tell me where to look?
Thanks a million

The output speed sensor can be serviced without having to remove the
transaxle from the vehicle.

CAUTION: When disconnecting speed sensor connector, be sure that the weather
seal does not fall off or remain in old sensor.

The output speed sensor is located on the left side of the transaxle case.
The sensor threads into the transaxle case. Tighten output speed sensor to
20-34 N·m (180-300 in. lbs.)

 

replace the output speed sensor on the trans it's in limp in mode

 

it has the tan plastic base there are 2 and the one you want is rearward

 

So's the input speed sensor. The output sensor is the one towards the rear.

Thanks guys, it was an easy fix, cheep too $19 for the sensor and $5 for
a deepwell socket to take it off. The check engine light is still on though.
Thanks again

No speedometer is almost always caused by a bad output speed sensor. Glad
to hear this fixed your trans problem. Did you remove the battery cable to
reset the computer? What is/are the engine diagnostic codes?

Codes were 0700 and 1684 (I had the starter out a while back) I'll go
out right now and reset the engine light. Thanks for your help.
